The place for everything bitcoin!

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no one in charge of bitcoin and it is made up of willing participants. Bitcoin gives you the option to be your own bank.

Meet Brock Pierce, the Presidential Candidate With Ties to Pedophiles Who Wants to End Human Trafficking

thedailybeast.com | Sep. 20, 2020.
The “Mighty Ducks” actor is running for president. He clears the air (sort of) to Tarpley Hitt about his ties to Jeffrey Epstein and more.
In the trailer for First Kid, the forgettable 1996 comedy about a Secret Service agent assigned to protect the president’s son, the title character, played by a teenage Brock Pierce, describes himself as “definitely the most powerful kid in the universe.” Now, the former child star is running to be the most powerful man in the world, as an Independent candidate for President of the United States.
Before First Kid, the Minnesota-born actor secured roles in a series of PG-rated comedies, playing a young Emilio Estevez in The Mighty Ducks, before graduating to smaller parts in movies like Problem Child 3: Junior in Love. When his screen time shrunk, Pierce retired from acting for a real executive role: co-founding the video production start-up Digital Entertainment Network (DEN) alongside businessman Marc Collins-Rector. At age 17, Pierce served as its vice president, taking in a base salary of $250,000.
DEN became “the poster child for dot-com excesses,” raising more than $60 million in seed investments and plotting a $75 million IPO. But it turned into a shorthand for something else when, in October of 1999, the three co-founders suddenly resigned. That month, a New Jersey man filed a lawsuit alleging Collins-Rector had molested him for three years beginning when he was 13 years old. The following summer, three teens filed a sexual-abuse lawsuit against Pierce, Collins-Rector, and their third co-founder, Chad Shackley. The plaintiffs later dropped their case against Pierce (he made a payment of $21,600 to one of their lawyers) and Shackley. But after a federal grand jury indicted Collins-Rector on criminal charges in 2000, the DEN founders left the country. When Interpol arrested them in 2002, they said they had confiscated “guns, machetes, and child pornography” from the trio’s beach villa in Spain.
While abroad, Pierce had pivoted to a new venture: Internet Gaming Entertainment, which sold virtual accessories in multiplayer online role-playing games to those desperate to pay, as one Wired reporter put it, “as much as $1,800 for an eight-piece suit of Skyshatter chain mail” rather than earn it in the games themselves. In 2005, a 25-year-old Pierce hired then-Goldman Sachs banker Steve Bannon—just before he would co-found Breitbart News. Two years later, after a World of Warcraft player sued the company for “diminishing” the fun of the game, Steve Bannon replaced Pierce as CEO.
Collins-Rector eventually pleaded guilty to eight charges of child enticement and registered as a sex offender. In the years that followed, Pierce waded into the gonzo economy of cryptocurrencies, where he overlapped more than once with Jeffrey Epstein, and counseled him on crypto. In that world, he founded Tether, a cryptocurrency that bills itself as a “stablecoin,” because its value is allegedly tied to the U.S. dollar, and the blockchain software company Block.one. Like his earlier businesses, Pierce’s crypto projects see-sawed between massive investments and curious deals. When Block.one announced a smart contract software called EOS.IO, the company raised $4 billion almost overnight, setting an all-time record before the product even launched. The Securities and Exchange Commission later fined the company $24 million for violating federal securities law. After John Oliver mocked the ordeal, calling Pierce a “sleepy, creepy cowboy,” Block.one fired him. Tether, meanwhile, is currently under investigation by the New York Attorney General for possible fraud.
On July 4, Pierce announced his candidacy for president. His campaign surrogates include a former Cambridge Analytica director and the singer Akon, who recently doubled down on developing an anonymously funded, $6 billion “Wakanda-like” metropolis in Senegal called Akon City. Pierce claims to be bipartisan, and from the 11 paragraphs on the “Policy” section of his website it can be hard to determine where he falls on the political spectrum. He supports legalizing marijuana and abolishing private prisons, but avoids the phrase “climate change.” He wants to end “human trafficking.” His proposal to end police brutality: body cams.
His political contributions tell a more one-sided story. Pierce’s sole Democratic contribution went to the short-lived congressional run of crypto candidate Brian Forde. The rest went to Republican campaigns like Marco Rubio, Rick Perry, John McCain, and the National Right to Life Political Action Committee. Last year alone, Pierce gave over $44,000 to the Republican National Committee and more than $55,000 to Trump’s re-election fund.
Pierce spoke to The Daily Beast from his tour bus and again over email. Those conversations have been combined and edited for clarity.
You’re announcing your presidential candidacy somewhat late, and historically, third-party candidates haven’t had the best luck with the executive office. If you don’t have a strong path to the White House, what do you want out of the race?
I announced on July 4, which I think is quite an auspicious date for an Independent candidate, hoping to bring independence to this country. There’s a lot of things that I can do. One is: I’m 39 years old. I turn 40 in November. So I’ve got time on my side. Whatever happens in this election cycle, I’m laying the groundwork for the future. The overall mission is to create a third major party—not another third party—a third major party in this country. I think that is what America needs most. George Washington in his closing address warned us about the threat of political parties. John Adams and the other founding fathers—their fear for our future was two political parties becoming dominant. And look at where we are. We were warned.
I believe, having studied systems, any time you have a system of two, what happens is those two things come together, like magnets. They come into collision, or they become polarized and become completely divided. I think we need to rise above partisan politics and find a path forward together. As Albert Einstein is quoted—I’m not sure the line came from him, but he’s quoted in many places—he said that the definition of insanity is making the same mistake or doing the same thing over and over and over again, expecting a different result. [Ed. note: Einstein never said this.] It feels like that’s what our election cycle is like. Half the country feels like they won, half the country feels like they lost, at least if they voted or participated.
Obviously, there’s another late-comer to the presidential race, and that’s Kanye West. He’s received a lot of flak for his candidacy, as he’s openly admitted to trying to siphon votes away from Joe Biden to ensure a Trump victory. Is that something you’re hoping to avoid or is that what you’re going for as well?
Oh no. This is a very serious campaign. Our campaign is very serious. You’ll notice I don’t say anything negative about either of the two major political candidates, because I think that’s one of the problems with our political system, instead of people getting on stage, talking about their visionary ideas, inspiring people, informing and educating, talking about problems, mentioning problems, talking about solutions, constructive criticism. That’s why I refuse to run a negative campaign. I am definitely not a spoiler. I’m into data, right? I’m a technologist. I’ve got digital DNA. So does most of our campaign team. We’ve got our finger on the pulse.
Most of my major Democratic contacts are really happy to see that we’re running in a red state like Wyoming. Kanye West’s home state is Wyoming. He’s not on the ballot in Wyoming I could say, in part, because he didn’t have Akon on his team. But I could also say that he probably didn’t want to be on the ballot in Wyoming because it’s a red state. He doesn’t want to take additional points in a state where he’s only running against Trump. But we’re on the ballot in Wyoming, and since we’re on the ballot in Wyoming I think it’s safe—more than safe, I think it’s evident—that we are not here to run as a spoiler for the benefit of Donald Trump.
In running for president, you’ve opened yourself up to be scrutinized from every angle going back to the beginning of your career. I wanted to ask you about your time at the Digital Entertainment Network. Can you tell me a little bit about how you started there? You became a vice president as a teenager. What were your qualifications and what was your job exactly?
Well, I was the co-founder. A lot of it was my idea. I had an idea that people would use the internet to watch videos, and we create content for the internet. The idea was basically YouTube and Hulu and Netflix. Anyone that was around in the ‘90s and has been around digital media since then, they all credit us as the creators of basically those ideas. I was just getting a message from the creator of The Vandals, the punk rock band, right before you called. He’s like, “Brock, looks like we’re going to get the Guinness Book of World Records for having created the first streaming television show.”
We did a lot of that stuff. We had 30 television shows. We had the top most prestigious institutions in the world as investors. The biggest names. High-net-worth investors like Terry Semel, who’s chairman and CEO of Warner Brothers, and became the CEO of Yahoo. I did all sorts of things. I helped sell $150,000 worth of advertising contracts to the CEOs of Pepsi and everything else. I was the face of the company, meeting all the major banks and everything else, selling the vision of what the future was.
You moved in with Marc Collins-Rector and Chad Shackley at a mansion in Encino. Was that the headquarters of the business?
All start-ups, they normally start out in your home. Because it’s just you. The company was first started out of Marc’s house, and it was probably there for the first two or three months, before the company got an office. That’s, like, how it is for all start-ups.
were later a co-defendant in the L.A. County case filed against Marc Collins-Rector for plying minors with alcohol and drugs, in order to facilitate sexual abuse. You were dropped from the case, but you settled with one of the men for $21,600. Can you explain that?
Okay, well, first of all, that’s not accurate. Two of the plaintiffs in that case asked me if I would be a plaintiff. Because I refused to be a part of the lawsuit, they chose to include me to discredit me, to make their case stronger. They also went and offered 50 percent of what they got to the house management—they went around and offered money to anyone to participate in this. They needed people to corroborate their story. Eventually, because I refused to participate in the lawsuit, they named me. Subsequently, all three of the plaintiffs apologized to me, in front of audiences, in front of many people, saying Brock never did anything. They dismissed their cases.
Remember, this is a civil thing. I’ve never been charged with a crime in my life. And the last plaintiff to have his case dismissed, he contacted his lawyer and said, “Dismiss this case against Brock. Brock never did anything. I just apologized. Dismiss his case.” And the lawyer said, “No. I won’t dismiss this case, I have all these out-of-pocket expenses, I refuse to file the paperwork unless you give me my out-of-pocket expenses.” And so the lawyer, I guess, had $21,000 in bills. So I paid his lawyer $21,000—not him, it was not a settlement. That was a payment to his lawyer for his out-of-pocket expenses. Out-of-pocket expenses so that he would file the paperwork to dismiss the case.
You’ve said the cases were unfounded, and the plaintiffs eventually apologized. But your boss, Marc Collins-Rector later pleaded guilty to eight charges of child enticement and registered as a sex offender. Were you aware of his behavior? How do you square the fact that later allegations proved to be true, but these ones were not?
Well, remember: I was 16 and 17 years old at the time? So, no. I don’t think Marc is the man they made him out to be. But Marc is not a person I would associate with today, and someone I haven’t associated with in a very long time. I was 16 and 17. I chose the wrong business partner. You live and you learn.
You’ve pointed out that you were underage when most of these allegations were said to take place. Did you ever feel like you were coerced or in over your head while working at DEN?
I mean, I was working 18 hours a day, doing things I’d never done before. It was business school. But I definitely learned a lot in building that company. We raised $88 million. We filed our [form] S-1 to go public. We were the hottest start-up in Los Angeles.
In 2000, you left the country with Marc Collins-Rector. Why did you leave? How did you spend those two years abroad?
I moved to Spain in 1999 for personal reasons. I spent those two years in Europe working on developing my businesses.
Interpol found you in 2002. The house where you were staying reportedly contained guns, machetes, and child pornography. Whose guns and child porn were those? Were you aware they were in the house, and how did those get there?
My lawyers have addressed this in 32 pages of documentation showing a complete absence of wrongdoing. Please refer to my webpage for more information.
[Ed. Note: The webpage does not mention guns, machetes, or child pornography. It does state:“It is true that when the local police arrested Collins-Rector in Spain in 2002 on an international warrant, Mr. Pierce was also taken into custody, but so was everyone at Collins-Rector’s house in Spain; and it is equally clear that Brock was promptly released, and no charges of any kind were ever filed against Brock concerning this matter.”]
What do you make of the allegations against Bryan Singer? [Ed. Note: Bryan Singer, a close friend of Collins-Rector, invested at least $50,000 in DEN. In an Atlantic article outlining Singer’s history of alleged sexual assault and statutory rape, one source claimed that at age 15, Collins-Rector abused him and introduced him to Singer, who then assaulted him in the DEN headquarters.]
I am aware of them and I support of all victims of sexual assault. I will let America’s justice system decide on Singer’s outcome.
In 2011, you spoke at the Mindshift conference supported by Jeffrey Epstein. At that point, he had already been convicted of soliciting prostitution from a minor. Why did you agree to speak?
I had never heard of Jeffrey Epstein. His name was not on the website. I was asked to speak at a conference alongside Nobel Prize winners. It was not a cryptocurrency conference, it was filled with Nobel Prize winners. I was asked to speak alongside Nobel Prize winners on the future of money. I speak at conferences historically, two to three times a week. I was like, “Nobel Prize winners? Sounds great. I’ll happily talk about the future of money with them.” I had no idea who Jeffrey Epstein was. His name was not listed anywhere on the website. Had I known what I know now? I clearly would have never spoken there. But I spoke at a conference that he cosponsored.
What’s your connection to the Clinton Global Initiative? Did you hear about it through Jeffrey Epstein?
I joined the Clinton Global Initiative as a philanthropist in 2006 and was a member for one year. My involvement with the Initiative had no connection to Jeffrey Epstein whatsoever.
You’ve launched your campaign in Minnesota, where George Floyd was killed by a police officer. How do you feel about the civil uprising against police brutality?
I’m from Minnesota. Born and raised. We just had a press conference there, announcing that we’re on the ballot. Former U.S. Senator Dean Barkley was there. So that tells you, when former U.S. Senators are endorsing the candidate, right?
[Ed. note: Barkley was never elected to the United States Senate. In November of 2002, he was appointed by then Minnesota Governor Jesse Venture to fill the seat after Sen. Paul Wellstone died in a plane crash. Barkley’s term ended on Jan. 3, 2003—two months later.]
Yes, George Floyd was murdered in Minneapolis. My vice-presidential running mate Karla Ballard and I, on our last trip to Minnesota together, went to visit the George Floyd Memorial. I believe in law and order. I believe that law and order is foundational to any functioning society. But there is no doubt in my mind that we need reform. These types of events—this is not an isolated incident. This has happened many times before. It’s time for change. We have a lot of detail around policy on this issue that we will be publishing next week. Not just high-level what we think, not just a summary, but detailed policy.
You said that you support “law and order.” What does that mean?
“Law and order” means creating a fair and just legal system where our number one priority is protecting the inalienable rights of “Life, Liberty and the pursuit of Happiness” for all people. This means reforming how our police intervene in emergency situations, abolishing private prisons that incentivize mass incarceration, and creating new educational and economic opportunities for our most vulnerable communities. I am dedicated to preventing crime by eliminating the socioeconomic conditions that encourage it.
I support accountability and transparency in government and law enforcement. Some of the key policies I support are requiring body-cams on all law enforcement officers who engage with the public, curtailing the 1033 program that provides local law enforcement agencies with access to military equipment, and abolishing private prisons. Rather than simply defund the police, my administration will take a holistic approach to heal and unite America by ending mass incarceration, police brutality, and racial injustice.
Did you attend any Black Lives Matter protests?
I support all movements aimed at ending racial injustice and inequality. I​ have not attended any Black Lives Matter protests.​ My running-mate, Karla Ballard, attended the March on Washington in support of racial justice and equality.
Your platform doesn’t mention the words “climate change.” Is there a reason for that?
I’m not sure what you mean. Our policy platform specifically references human-caused climate change and we have a plan to restabilize the climate, address environmental degradation, and ensure environmental sustainability.
[Ed. Note: As of writing the Pierce campaign’s policy platform does not specifically reference human-caused climate change.]
You’ve recently brought on Akon as a campaign surrogate. How did that happen? Tell me about that.
Akon and I have been friends for quite some time. I was one of the guys that taught him about Bitcoin. I helped make some videogames for him, I think in 2012. We were talking about Bitcoin, teaching him the ropes, back in 2013. And in 2014, we were both speaking at the Milken Global Conference, and I encouraged him to talk about how Bitcoin, Africa, changed the world. He became the biggest celebrity in the world, talking about Bitcoin at the time. I’m an adviser to his Akoin project, very interested in the work that he’s doing to build a city in Africa.
I think we need a government that’s of, for, and by the people. Akon has huge political aspirations. He obviously was a hugely successful artist. But he also discovered artists like Lady Gaga. So not only is he, himself, a great artist, but he’s also a great identifier and builder of other artists. And he’s been a great businessman, philanthropist. He’s pushing the limits of what can be done. We’re like-minded individuals in that regard. I think he’ll be running for political office one day, because he sees what I see: that we need real change, and we need a government that is of, for, and by the people.
You mentioned that you’re an adviser on Akoin. Do you have any financial investments in Akoin or Akon City?
I don’t believe so. I’d have to check. I have so much stuff. But I don’t believe that I have any economic interests in his stuff. I’d have to verify that. We’ll get back to you. I don’t believe that I have any economic interests. My interest is in helping him. He’s a visionary with big ideas that wants to help things in the world. If I can be of assistance in helping him make the world a better place, I’m all for it. I’m not motivated by money. I’m not running for office because I’m motivated by power. I’m running for office because I’m deeply, deeply concerned about our collective future.
You’ve said you’re running on a pro-technology platform. One week into your campaign last month, a New York appeals court approved the state Attorney General’s attempt to investigate the stablecoin Tether for potentially fraudulent activity. Do you think this will impact your ability to sell people on your tech entrepreneurship?
No, I think my role in Tether is as awesome as it gets. It was my idea. I put it together. But I’ve had no involvement in the company since 2015. I gave all of my equity to the other shareholders. I’ve had zero involvement in the company for almost six years. It was just my idea. I put the initial team together. But I think Tether is one of the most important innovations in the world, certainly. The idea is, I digitized the U.S. dollar. I used technology to digitize currency—existing currency. The U.S. dollar in particular. It’s doing $10 trillion a year. Ten trillion dollars a year of transactional volume. It’s probably the most important innovation in currency since the advent of fiat money. The people that took on the business and ran the business in years to come, they’ve done things I’m not proud of. I’m not sure they’ve done anything criminal. But they certainly did things differently than I would do. But it’s like, you have kids, they turn 18, they go out into the world, and sometimes you’re proud of the things they do, and sometimes you shake your head and go, “Ugh, why did you do that?” I have zero concerns as it relates to me personally. I wish they made better decisions.
What do you think the investigation will find?
I have no idea. The problem that was raised is that there was a $5 million loan between two entities and whether or not they had the right to do that, did they disclose it correctly. There’s been no accusations of, like, embezzlement or anything that bad.
[Ed. Note: The Attorney General’s press release on the investigation reads: “Our investigation has determined that the operators of the ‘Bitfinex’ trading platform, who also control the ‘tether’ virtual currency, have engaged in a cover-up to hide the apparent loss of $850 million dollars of co-mingled client and corporate funds.”]
But there’s been some disclosure things, that is the issue. No one is making any outrageous claims that these are people that have done a bunch of bad—well, on the internet, the media has said that the people behind the business may have been manipulating the price of Bitcoin, but I don’t think that has anything to do with the New York investigation. Again, I’m so not involved, and so not at risk, that I’m not even up to speed on the details.
[Ed note: A representative of the New York State Attorney General told Forbes that he “cannot confirm or deny that the investigation” includes Pierce.]
We’ve recently witnessed the rise of QAnon, the conspiracy theory that Hollywood is an evil cabal of Satanic pedophiles and Trump is the person waging war on them. You mentioned human trafficking, which has become a cause for them. What are your thoughts on that?
I’ve watched some of the content. I think it’s an interesting phenomenon. I’m an internet person, so Anonymous is obviously an organization that has been doing interesting stuff. It’s interesting. I don’t have a big—conspiracy theory stuff is—I guess I have a question for you: What do you think of all of it, since you’re the expert?
You know, I think it’s not true, but I’m not running for president. I do wonder what this politician [Georgia congressional candidate Marjorie Taylor Greene], who’s just won her primary, is going to do on day one, once she finds out there’s no satanic cabal room.
Wait, someone was running for office and won on a QAnon platform, saying that Hollywood did—say what? You’re the expert here.
She won a primary. But I want to push on if we only have a few minutes. In 2006, your gaming company IGE brought on Steve Bannon as an investor. Goldman later bought out most of your stock. Bannon eventually replaced you as CEO of Affinity. You’ve described him as your “right-hand man for, like, seven years.” How well did you know Bannon during that time?
Yes, so this is in my mid-twenties. He wasn’t an investor. He worked for me. He was my banker. He worked for me for three years as my yield guide. And then he was my CEO running the company for another four years. So I haven’t worked with Steve for a decade or so. We worked in videogame stuff and banking. He was at Goldman Sachs. He was not in the political area at the time. But he was a pretty successful banker. He set up Goldman Sachs Los Angeles. So for me, I’d say he did a pretty good job.
During your business relationship, Steve Bannon founded Breitbart News, which has pretty consistently published racist material. How do you feel about Breitbart?
I had no involvement with Breitbart News. As for how I feel about such material, I’m not pleased by any form of hate-mongering. I strongly support the equality of all Americans.
Did you have qualms about Bannon’s role in the 2016 election?
Bannon’s role in the Trump campaign got me to pay closer attention to what he was doing but that’s about it. Whenever you find out that one of your former employees has taken on a role like that, you pay attention.
Bannon served on the board of Cambridge Analytica. A staffer on your campaign, Brittany Kaiser, also served as a business director for them. What are your thoughts on their use of illicitly-obtained Facebook data for campaign promotional material?
Yes, so this will be the last question I can answer because I’ve got to be off for this 5:00 pm. But Brittany Kaiser is a friend of mine. She was the whistleblower of Cambridge Analytica. She came to me and said, “What do I do?” And I said, “Tell the truth. The truth will set you free.”
[Ed. Note: Investigations in Cambridge Analytica took place as early as Nov. 2017, when a U.K. reporter at Channel 4 News recorded their CEO boasting about using “beautiful Ukranian girls” and offers of bribes to discredit political officials. The first whistleblower was Christopher Wylie, who disclosed a cache of documents to The Guardian, published on Mar. 17, 2018. Kaiser’s confession ran five days later, after the scandal made national news. Her association with Cambridge Analytica is not mentioned anywhere on Pierce’s campaign website.]
So I’m glad that people—I’m a supporter of whistleblowers, people that see injustice in the world and something not right happening, and who put themselves in harm’s way to stand up for what they believe in. So I stand up for Brittany Kaiser.
Who do you think [anonymous inventor of Bitcoin] Satoshi Nakamoto is?
We all are Satoshi Nakamoto.
You got married at Burning Man. Have you been attending virtual Burning Man?
I’m running a presidential campaign. So, while I was there in spirit, unfortunately my schedule did not permit me to attend.

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

Pi Network! This golden project is an opportunity.

  1. What is Pi Network?
Pi Network is a virtual currency that can only be mined or mined on a phone, but does not consume device resources like other free mining applications. Previously Pi Network could include mining applications such as Electroneum (ETN), but this application consumes your device resources to decode the algorithm (Electroneum uses cryptonight algorithm). With Pi Network, when you dig coins will feel the device does not heat up. In addition, you can also turn off the application or turn off the network and still be able to mine coins every 24 hours.

Note:

Pi Network is still in BETA. The project is still in progress which means that there will still be errors and some details of the project are still changing. While many cryptocurrency projects start from pure theory, Pi Network seeks to balance theory with design and people-centered (or experiment with real people to best meet their needs). ). The project appreciates your patience and welcomes your input as we work together to develop products that best meet community needs. Pi does NOT give you free money. This is a long-term project whose success depends on the common contribution of its members. Pi helps people capture economic value, which is held by banks, technology giants (e.g. Facebook, Amazon) and other intermediaries. Pi depends on the contribution of the members. Therefore Pi NetWork is not suitable for those who want to make money quickly.

2. Is Pi Network scam?

Pi is not a hoax. This is an attempt by a group of Stanford University alumni to spread the cryptocurrency to more people. Pi Network's core team is led by two Stanford PhDs and one Stanford MBA, all of which help build the blockchain community at Stanford. There is no guarantee that the project will succeed. However, Pi Network will work hard to make common dreams a reality, while upholding the highest standards of transparency. You can learn more about Pi's core team on the app, or simply by typing these people 's names into the Google search page:
- Nicolas Kokkalis: Head of Technology
- Department Chengdiao Fan: Vincent
- McPhillip Product Manager: Community Manager

3. How to make money with Pi Network?

How to exploit Pi
Pi Network does not call you to invest or do anything. Your job is very simple, you just need to have a phone, download the Pi Network app and create an account, press the Start button daily and the PI digging will take place even if your computer is not connected to the internet . You also do not need to open the active application. Pi does not affect your phone performance, does not drain your battery or use your network data. To start earning Pi, check the app every 24 hours and press the lightning button to start mining. You can increase your hourly Pi rate by inviting friends and family to join the community. After 3 days of exploitation, you can increase your income even more by building your security circle, which contributes to the overall security of the network. And remember, veterans of the network have a higher rate of extraction than the members who come after them.
Why are veteran members exploiting more?
Pi's goal is to become a widely distributed and widely used electronic currency in the world. To achieve that goal, Pi encourages members to contribute early to ensure the success of the project (eg network protection and development). To reflect the importance of early contributions, the rate of extraction decreases as more people join the network. At this point, the base mining rate will be halved every time the number of active users increases by 10 times. This ratio will be reduced to zero when the network reaches a certain number of users (for example, 10 million or 100 million). At the time, like Bitcoin, miners would continue to receive rewards with transaction fees, rather than being rewarded with new coins.
What is the Pi Network security circle?
The security circle is a group of 3-5 trusted people built by each Pi member, to prevent fraudulent transactions. While cryptocurrencies like Bitcoin secure their ledgers by forcing mining companies to burn energy (proof of work), Pi still guarantees its ledger when members of the network prove trust with each other. Pi contributors guarantee each other by building up security groups of 3-5 members whom they deem reliable. The security circle should include people you trust not to make fraudulent transactions. The cyber security circles form a global trust chart to determine who can trust to conduct transactions on the Pi ledger.

4. What is the Pi price?

Pi is worth approximately 0 dollars / euro. Yes! If the price is $ 0, then we dig PI do? Also you wonder when PIs will be valuable? While everyone thinks that PIs are not valuable and do not participate, just like when BITCOIN 2008 had no value. If you are a PI holder PI holders have two options to convert PIs into cash:
- Buy goods and services directly with your Pi. Pi Network is building a peer-to-peer market where members can directly spend Pi to buy goods and services. Pi Network aims to start a bank transfer test in its application immediately after Q42019.
- Exchange Pi for cash on cryptocurrency exchanges. Pi will be able to be traded during Phase 3 of the project (such as when launching the Mainnet). At that time, exchanges may choose to list Pi. At this point, Pi's core team focuses on implementing the right technical roadmap to reach phase 3.
(I still remember in 2015, in MMO communities, competing to receive free coins called Raiblocks (XRB) by typing captcha, each type of such a lot of XRB, it can be said that the day that XRB has no price value, almost 0. Later in early 2018 when Raiblocks changed its name to NANO project, the peak of 1 NANO coin reached 34 USD, sweeping away the dream of millionaires of MMO people, because at XRB, they sell very cheaply for each other. You can refer to the NANO price chart below)

If the Pi application verifies that you have successfully verified your account.

7. How to draw Pi?

You cannot withdraw the Pi. You will be able to withdraw Pi or exchange Pi for other currencies during Phase 3 of the project, when Pi switches to a completely decentralized blockchain. Phase 1 of Project Pi is on March 14, 2019 (Pi Day). In Stage 1, your balance is being recorded to wait for the day Pi reaches the mainnet (Phase 3). The transfer or withdrawal of Pi is restricted until the mainnet launch, to prevent fraudulent actions, such as clone users to dig Pi, then transfer Pi to another account and legalize the process. verify your account and use that nefarious Pi number.

8. Should you dig Pi on multiple phones?

No, you SHOULD NOT dig PI on many devices. Pi Network adheres to a strict rule, meaning that only one account can be used per person. Pi Network uses a multi-pronged strategy to ensure that fake accounts cannot exploit Pi
First, the Pi network uses Google Recaptcha v3 to know which devices are operated by humans or robots. (This technology is completely invisible to most users, because they are real people, but robots can see the captcha if the google algorithm captures them.) Over time, Pi Network is developing a machine learning algorithm based on actual user exploitation behavior to predict bots.
Second, the Pi consensus algorithm (security circle) makes it easy to detect fake accounts. The fake account will not have enough real people to link to them through the security circle. Thus fake accounts will have less linkage with the rest of the network. This anomaly is easy to detect with computer algorithms.
Finally, when Pi enters Stage 3 and 4 - Mainnet, only authenticated accounts can exist. Buy

9. Where to buy and sell Pi?

Currently, there is only 1 exchange, AACoin listed PI (https://www.aacoin.com/trade/PI\_USDT) in the form of short purchase and sale, meaning that they buy and sell PI but do not actually own any PI. Because PIs have not been withdrawn until entering phase 3 (mainnet), all PI trading platforms are fraudulent. The Pi Core team also issued a warning. In addition, users should not buy and sell Pi transactions on the black market through the sale of accounts, because all of us have not been able to price Pi, so there are many potential risks.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.
