Welcome to the /Bitcoin Sticky FAQ
You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper
however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net
, the Princeton crypto series
and James D'Angelo's Bitcoin 101 Blackboard series
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute
Some Bitcoin statistics can be found here

Key properties of Bitcoin
- Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary. The halving countdown can be found here.
- Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
- Accountable - The public ledger is transparent, all transactions are seen by everyone.
- Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works. You can even run a node on a Raspberry Pi.
- Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
- Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
- Low fee scaling - On chain transaction fees depend on network demand and how much priority you wish to assign to the transaction. Most wallets calculate on chain fees automatically but you can view current fees here and mempool activity here. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, a second layer scaling solution currently rolling out on the Bitcoin mainnet.
- Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
- Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
- Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
- Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
- Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
- Nearly instant - From a few seconds to a few minutes depending on need for confirmations. Transactions are irreversible after one or more confirmations.
- Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
- Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply memorizing a string of words for wallet recovery (while cool this method is generally not recommended due to potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for new users due to ease of use and additional security).
- Scalable - While the protocol is still being optimized for increased transaction capacity, blockchains do not scale very well, so most transaction volume is expected to occur on Layer 2 networks built on top of Bitcoin.
- Divisible - Each bitcoin can be divided down to 8 decimals, which means you don't have to worry about buying an entire bitcoin.
- Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Where can I buy bitcoins? Bitcoin.org
are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources
for a larger list of options for purchases. Here
is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage
Bitcoins are valued at whatever market price
people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev
is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".
Securing your bitcoins
With bitcoin you can "Be your own bank"
and personally secure your bitcoins OR
you can use third party companies aka "Bitcoin banks"
which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
- If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor, Ledger or ColdCard is recommended. Alternatively there are many software wallet options to choose from here depending on your use case.
- If you prefer to let third party "Bitcoin banks" manage your coins, try Gemini but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Watch out for scams
As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

If you are interested in accepting bitcoin as a payment method, there are several options available;
Can I mine bitcoin?
Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home

The following is a short
list of ongoing projects that might be worth taking a look at if you are interested in current development in the bitcoin space.
One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
|Unit ||Symbol ||Value ||Info |
|bitcoin ||BTC ||1 bitcoin ||one bitcoin is equal to 100 million satoshis |
|millibitcoin ||mBTC ||1,000 per bitcoin ||used as default unit in recent Electrum wallet releases |
|bit ||bit ||1,000,000 per bitcoin ||colloquial "slang" term for microbitcoin (μBTC) |
|satoshi ||sat ||100,000,000 per bitcoin ||smallest unit in bitcoin, named after the inventor |
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:
- 0.001 BTC
- 1 mBTC
- 1,000 bits
- 100k sats

Welcome to the Bitcoin community and the new decentralized economy!
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/18.104.22.168 submitted by
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER
the v11 transition (around Oct 4th) and BEFORE
October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
- Network magnitude unit pinned to a static value of 0.25
- Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
- New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
- 500 GRC research reward limit for a CPID's first stake
- 6-month expiration for unclaimed rewards
- 10-block spacing requirement between research reward claims
- Rolling 5-day payment-per-day limit
- Legacy tolerances for floating-point error and time drift
- The need to include a valid copy of a CPID's magnitude in a claim
- 10-block emission adjustment interval for the magnitude unit
- One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
- Verification codes of pending beacons expire after 3 days
- Self-service beacon removal
- Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
- Rain addresses derived from beacon keys instead of a default wallet address
- Beacon expiration determined as of the current block instead of the previous block
- The ability for developers to remove beacons
- The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
- Beacons expire after 6 months pass (180 days)
- Beacons can be renewed after 5 months pass (150 days)
- Renewed beacons must be signed with the same key as the original beacon
- Magnitudes less than 1 include two fractional places
- Magnitudes greater than or equal to 1 but less than 10 include one fractional place
- A valid superblock must match a scraper convergence
- Superblock popularity election mechanics
- Yes/no/abstain and single-choice response types (no user-facing support yet)
- To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
- Burn fee for creating polls scaled by the number of UTXOs claimed
- 50 GRC for a poll contract
- 0.001 GRC per claimed UTXO
- Burn fee for casting votes scaled by the number of UTXOs claimed
- 0.01 GRC for a vote contract
- 0.01 GRC to claim magnitude
- 0.01 GRC per claimed address
- 0.001 GRC per claimed UTXO
- Maximum length of a poll title: 80 characters
- Maximum length of a poll question: 100 characters
- Maximum length of a poll discussion website URL: 100 characters
- Maximum number of poll choices: 20
- Maximum length of a poll choice label: 100 characters
- Magnitude, CPID count, and participant count poll weight types
- The ability for developers to remove polls and votes

As some of you know, I only make stupidly long posts and also like to
brag about being a software engineer with fairly decent experience in QA, automated testing and testing in general (6+ years a C# dev).
This is my personal list of things that either make no sense, are unpleasant, incoherent, or could be improved.
Please feel free to add to the list, I will come back and edit every day.
Numbers are also here to help you quote & provide your own criticism.
Note that is is done with the following optimization mindset, in order of importance :
- Remove redundancy / incoherence
- Reduce time spent in menus/inventory (out of raid)
- Reduce number of clicks / interactions
As you can see I worked under the assumption that the average player wants to spend more time in raid rather than in inventory ; obviously this falls apart if that is not the case. To do that I try to improve time spent on searching / arranging things without creating unecessary automation or remove important/immersive aspects of the game, even in inventory. I also try to improve time spent clicking through various windows as currently a lot of them are done to be fast & easy to for the devs, not for the players. I want to emphasize that I'm okay with that. I know the importance of having sub-optimal navigation to help you find out what your better navigation is. I also know a complete rework is not always possible, that is why I made my list without changing too much of the menus as well as keeping the vibe/current feel of those menus.
Keywords like should
are used as intended ; since this is not a professional report I'm emphasizing here, the meaning of the word is important. Should
means it is adding an improvement over an existing issue, could
means it's a possible improvement but requires further investigation. Would
means investigation was done and is just one possible outcome usually relevant within the context.
Please note that most of us now are very
used to the current UI/UX, which will generate two reactions:
- "It's fine as it is because I can do it quite fast."
- "I don't want it to change again, I'm used to it now."
I cannot emphasize how unefficient it is to let those emotions get the best of you. UI/UX is the study of common sense & ease of use in an interface. You should
never have to get used to anything, it should
be fluid and intuitive. If you think you're fast now, that means it's possible to be slow. This is extremely bad
for a UI/UX standpoint. Everybody should
be able to navigate/understand the menus just as fast the 1st time than the 100th time (ideally). Keep this in mind when you read everything down here, because some stuff you probably won't like at first glance, but you will
get used to it very fast, and you will
gain a lot of time in the future, as well as new players.
1. Autostacking of items
Money & Ammo. When a stackable item or stack of items enter an inventory, it should
autostack itself to an available non-full stack, then fill other available stacks until there aren't any. At that point, the item should
just go at the top of the inventory as it is doing now. Autostacking should
*not* browse for sublayers of inventory.
Items drag & dropped on an inventory slot should
not be auto-stacked either (drag & drop overrides autostacking).
autostack when control clicking, or using "Receive all" from another inventory, or when dropping into a sublayer without
selecting a specific slot.
only stack FiR items together and non FiR items together.
Drag & Dropping would not stack in the same inventory layer. Drag & dropping would override auto stacking.
Dragging over the money case would auto stack in the inventory of the case.
Using Ammo as example here. If you drag & drop directly on a slot (even in an inventory sublayer), you would override autostacking.
2. Highlighting of full stacks
Stacks at full capacity could
be highlighted for easier inventory management.
Many aspects could be used to highlight (either the name of the item, or the value, or the background of the cell)
Apology for the poor photoshop skills
This could be a highlighting method
This could be a highlighting method
3. Consistent item order in hideout craft list
Currently when in the workbench (and I think others? now I doubt), the list of craftable items appears to be random. The order should
always be the same for consistency. Does not provide meaningful gameplay experience to have to "look for the recipe" every time.
4. Collecting crafts
Hideout stations could
display the finished craft on top for easy collection of craft, or there could
be a "Get Items" or "Receive All" elsewhere to avoid unecessary scrolling. This is uncessary if ongoing crafts are moved on top of the list, or if the list is autoscrolled to the ongoing craft.
"Collect All" on station level is not the best idea. If you go in a station, it's probably better that you know what you're collecting. I suggest moving the relevant craft on top or auto scrolling and not adding "receive all" on station level, although it would
be a good help.
This should be investigated.
Receive All or Get Items could be moved or added at the top or bottom of the window.
5. "Receive All" could exist at hideout level
The same way we "receive all" from a trader, it would
be nice to "Receive all" from the hideout. Either in the form of a trader (in which we can receive all / pick manually from) or by instantly putting it in inventory. If there is enough space it just works. If there isn't, it displays an error like it already does.
This is not mutually exclusive with the previous suggestion.
6. Display crafts readyness/collection 6.1
The current behaviour is partially coherent. You get notified when an item is sold, and you get notified when a craft is finished.
You have a display notification "Attachment" style when a trader has something for you, and you should
get a display notification "attachment" style when the hideout has something for you.
Ideally, there should also be such notifications for currently unused station
Receive all on the right, Nutrition unit has finished crafting and Lavatory is currently NOT crafting
be a way of knowing if something is waiting in trader inventory on a global level (quest rewards, money, insurance, unsold market items returns), like the nofication. The "new item" notification could
be always visible as long as items are in the trader inventories, compared to now where it disappears as soon as you either click it or visit the messenger. In this hypothesis, there could
be a change of color in the notification to show that there are still item waiting including
some that haven't been seen yet (to still fulfill the current role of the notification)
Note : CTA = Call to Action, it's the button your user will press 99.3% of the time. Example, in the launcher, it's the "Start Game". Clearly visible, easily accessible, highlighted, much bigger, and at a very common CTA spot. That one is great.
Some others are not. 7.1
. "Receive All" should not
be displayed when there is nothing to receive. 7.2
"Get" in single transaction messages from Ragman could
be removed. There is no reason to take single items from the window when you can receive it all at once.
7.3 A "group collect" Receive all action could
be added when you click on the attachment notification, or as an extra action next to the notification (just like shown on the Hideout in figure 6.0) that would specifically collect all. it would
loop through all conversations and collect all and dump at the top of stash, either until its finished or there is not enough room, in which case it displays an error. It could
also work like the scav case and not pick up anything until you have room, and in that case you would
go in the window manually and/or make room (like we do now). 7.3
The "Receive all" is at the bottom when most CTAs in the game is at the top (dealer tabs, market tabs, character sheet tabs, settings...). Save in the settings is at the bottom too. It is incoherent. It would
make more sense to have all CTAs at the bottom and options/tabs/menus at the top. 7.4
The "DEAL" button in trader view is much smaller and less visible than the "Fill Item" checkbox. The CTA should
be getting more attention than a setting. New players pretty much *never* see it first and look around the "Fill Item" with eyes & mouse.
DEAL should be at the bottom in the current \"Fill Item\" box. Fill Items should be removed entirely. 7.5
be automatically accepted (no need for CTA). I don't see a reason why someone would not accept a quest. The only reason we're Accepting them now is to let the user know he has a new quest. There are other means of notifying players of new stuff : usually notifications. If not, that button should at least be more visible/highlighted. Every new player ( 100%! )
I coach does not see it at first and never
looks at the right spot the first time. 7.6
"Insure All" is the most commonly used button in the insurance screen and could
be emphasized more.
8. Remove "Fill Items"
The Fill Items to automatically fill the trader's requirements should be removed and set as the default behaviour. There is no need to fill items manually nor tell the game to do so.
9. Expire / Delete pending requests
Friend requests should
be cancellable and could
expire. Requests should not be stuck until another
user acts on them. Right clicking the request could
display a "Cancel" or "Delete" request button.
Ideally, the cell should
include a CTA on the right, as the only action I would ever do in a cell in this context is cancel. Opening a submenu with only 1 item means you should not be opening a submenu, but displaying a button where the user right clicked instead.
I can only re-send a friend request to someone that already denied me. This is incoherent.
10. Market Rows
From my somewhat small sample (about 60 players), nobody uses the expand button on the top right of a cell (see below). I think everybody uses the right click on item instead.
An expanded cell with context menu opened, and a collapsed cell
The extra information available on the right is the exact same as a right click, but is hidden behind a left click.
This is incoherent.
The only difference is the profile picture that I only get from expanding, but currently we all have the same one. This would need to be investigated.
This could be an improvement, displaying the CTA's immediately (although BUY is definitely way too small). Notice profile picture on the left 10.1
The expandable cell feature should
be removed altogether, as the other options are available on right click. 10.2
The whole row should
provide the same context menu (right click). 10.3
The "Send friend request" could
be included in the row's context menu, or could
be removed entirely, as right now most requests are missclicks. Adding the Send Friend Request at the bottom of the context menu on the row would
reduce the amount of missclicks. 10.4
Left clicking should not
open the context menu. This is mostly the reason behind missclick friend requests, people double clicking slightly off the item icon sending a friend request by mistake. Now I have 4 just because I was trying to make a screenshot. F's in the chat. This would
be resolved with 10.2 and 10.3. 10.5
Barter items have a "Barter" icon that is redundant, the first and second column are completely irrelevant to the player.
11. Filtering search 11.1
"Filter by Item" should not
filter the browse list. If you're writing a valid keyword in the search field it should
display the correct suggestions. Filtering content is good, filtering suggestions is incoherent. 11.2
be cleared as soon as you type text in the search field. This would
Example 11 11.3
"My Offers" could
not be affected by filters, or could
reset filters. It is more trouble to remove the filter manually every time rather than browsing through the offer list. Currently we never have more than ~10 offers at the same time for most players, which is okay to display without filter. 11.4
Filters should not
overlap with other UI elements, they could
be resized to fit or the expandable filter list could
include more elements so the visible ones fit.
Example 11.4 11.5
The Remember Selected Filter / Reset Filter is unclear. Looks great, feels weird, and should be investigated to be more useful.
12. Context Menu in player lobby
The current lobby with context menu open
All players in this list are looking for a group, there is no need to write a status "Looking for group", it's redundant. The exception is friends, which 99.633...% of the time is the group i'm about to play with. Those are displayed on top.
The only action we do on the list on this screen is the "Invite to group" context menu action. It's a CTA and should not
be hidden in a context menu, especially if the context menu only has one option
. Since recently it has two, but we'll come to that in a minute. 12.1
The invite CTA should
be on the player cell itself. 12.2
The report action should not
be the default one from the context menu 12.3
Since there could be
only one item in the context menu according to 12.1, the report action could
be on the cell as well.
A low quality suggestion for 12.x
13. Trader Buy/Sell
Trader screen needs to be reworked. I won't provide a solution that doesn't completely change how everything looks/works as I stated at the start of the post. That being said this should
Example 13.1 13.1
Buying UI should
When buying, the price of the item is already displayed on the item itself in the trader view.
The price is also displayed a second time in the tooltip of the item if you mouse-over.
The price is also displayed a third time
in the barter area on the right of the image (middle of the screen in game). This is redundant. I understand the item on the right is the physical item "Roubles" in a stack that is paid, like a barter, but it does not need to be displayed a third time. 13.2
Quantity limit (red box in the image) could be
shown in the tooltip ; most of the time people will hit "DEAL" until they get an error insted of actually reading the red box. 13.3
The red box looks like an error even when at 0/x, this is not intuitive. Limited items can be listed in different ways that are not so invasive. We could
add "out of X" at the right side of the quantity box. 13.4
Barter item prices (if we assume 13.1) would
need to also displayed differently. This needs to be investigated 13.5
Selling UI should
Currently selling an item still displays the full available items to BUY
, this is incoherent. Especially from the "Sell" tab. The whole left side of the screen is wasted, and cannot be used. 13.6
Items on the left are not greyed out (even though I can't buy them), but items on the right are greyed out (because I can't sell them). This is incoherent. 13.7
Trader sell space should
be infinite 13.8
be done in a single tab if the whole screen is reworked. There are different levels to this. An easy one I could think :
"Trade" Tab instead of "Buy". Displays the same as the current "BUY" tab. If you ctrl+click an item from your stash, it instantly sells without confirmation. The second tab would be a "Buyback" where you can see what you sold in the current trade session. If you leave the screen your buyback is reset and items cannot be recovered. Another way would be to keep buybacks for the last X items. You would need to pay what you received to get back. The item would not lose it's FiR status. This preleminary and simplistic rework has issues, notably that you have to know to right click to sell. One way to fix that would
be to make right click sell to trader instead of control click, but that would definitely make missclicks the first few days (and buyback would
be investigated. 13.9
Currency exchange rates should
be easily available in relevant areas (Peacekeeper, Therapist and flea market) for all currencies (Rouble, Euro, Dollar, Bitcoin)
be boxables and moved around. At least to be dropped in boxes, ideally to be moved around freely.
There is a limit of 20 images. 🤷♂ Example 14
15. Quest inventory
If you loot too many quest items in a raid, you can end up not being able to loot it.
I assume this is by design and it is why you have limited quest item space.
The quest inventory could
be infinite if it's not by design to be limited.
The quest inventory should
be manageable. In my case i had a 1 slot item blocking me from taking the suitcase, I should
have been allowed to move that 1 slot item to the top or to the right of my inventory, clearing a whole line and letting me take the case.
Quest items could
be stored in backpack (and resized) ; since you lose them on death it's not relevant to the players looting you or you dying and that issue would be gone. Storing it in your stash would
also prevent you from losing it by going in raid with it by mistake. Taking it in raid or giving it to trader would
be a volontary action. It also makes much more sense that way as other quest items (that are also usable items) work that way.
Alright this ended up taking more time than my lunchbreak, and there is *much* more to write but for the time being I'll leave it at that and come tomorrow to add your suggestions or mine. See you in 24 hours.
In the last days we have been experiencing a sharp rise in price, which is historically correlated with many people transacting over the Bitcoin network. Many people transacting over the Bitcoin network implies that the blockspace is in popular demand, meaning that when you send a transaction, it has to compete with other transactions for the inclusion in one of the blocks in the future. Miners are motivated by profits and transactions that pay more than other transactions are preferred when mining a new block. Although the network is working as intended (blockspace is a scarce good, subject to supply/demand dynamics, regulated purely by fees), people who are unfamiliar with it might feel worried that their transaction is “stuck” or otherwise somehow lost or “in limbo”. This post attempts to explain how the mempool works, how to optimize fees and that one does not need to worry about their funds.
TL;DR: Your funds are safe. Just be patient* and it'll be confirmed at some point. A transaction either will be confirmed or it never leaves your wallet, so there is nothing to worry about in regards to the safety of your coins.
You can see how the mempool "ebbs and flows", and lower fee tx's get confirmed in the "ebb" times (weekends, nights): https://jochen-hoenicke.de/queue/#0,30d
* if you are in hurry there are things like RBF (Replace By Fee)
and CPFC (Child Pays For Parent)
, which you can use to boost your transaction fees; you will need an advanced wallet like Bitcoin Core or Electrum for that though. Keep also in mind that this is not possible with any transaction (RBF requires opt in before sending, f.ex). If nothing else works and your transaction really needs a soon confirmation, you can try and contact a mining pool to ask them if they would include your transaction. Some mining pools even offer a web-interface for this: 1
Here’s how Andreas Antonopoulos describes it
In bitcoin there is no "in transit". Transactions are atomic meaning they either happen all at once or don't happen at all. There is no situation where they "leave" one wallet and are not simultaneously and instantaneously in the destination address. Either the transaction happened or it didn't. The only time you can't see the funds is if your wallet is hiding them because it is tracking a pending transaction and doesn't want you to try and spend funds that are already being spent in another transaction. It doesn't mean the money is in limbo, it's just your wallet waiting to see the outcome. If that is the case, you just wait. Eventually the transaction will either happen or will be deleted by the network.
tl;dr: your funds are safe
How is the speed of confirmations determined in bitcoin?
Open this site: https://jochen-hoenicke.de/queue/#0,2w
Here you see how many transactions are currently (and were historically) waiting to be confirmed, i.e how many transactions are currently competing with your transaction for blockspace (=confirmation).
You can see two important things: the differently coloured layers, each layer representing a different fee (higher layer = higher fees). You can point at a layer and see which fees (expressed in sat/byte) are represented in this layer. You can then deduct which layer your own transaction is currently at, and how far away from the top your position is (miners work through the mempool always from the top, simply because the tx's on top pay them more). You can estimate that each newly mined block removes roughly 1.xMB from the top (see the third graph which shows the mempool size in MB). On average, a new block is produced every ten minutes. But keep in mind that over time more transactions come into the mempool, so there can be periods where transactions are coming faster than transactions being “processed” by miners.
The second important observation is that the mempool "ebbs and flows", so even the lower paid transactions are periodically being confirmed at some point.
In short: what determines the speed of a confirmation is A) how high you set the fees (in sat/byte), B) how many other transactions with same or higher fees are currently competing with yours and C) how many transactions with higher paid fees will be broadcast after yours.
A) you can influence directly, B) you can observe in real time, but C) is difficult to predict. So it's always a little tricky to tell when the first confirmation happens if you set your fees low. But it's quite certain that at some point even the cheap transactions will come through.
So what happens if my transaction stays unconfirmed for days or even weeks?
Transactions are being broadcast by the full nodes on the network. Each node can adjust their settings for how long they keep unconfirmed transactions in their mempool. That’s why there is not a fixed amount of time after which a transaction is dropped from the mempool, but most nodes drop unconfirmed tx’s after two weeks [IS THIS CORRECT?]. This means that in the absolute worst case the unconfirmed transaction will simply disappear from the network, as if it never happened. Keep in mind that in those two weeks the coins never actually leave your wallet. It’s just that your wallet doesn’t show them as “available”, but you still have options like RBF and CPFP to get your transaction confirmed with higher fees, or to “cancel” your transaction by spending the same coins onto another address with a higher fee.
Helpful tools to estimate fees for future transactions:
Here are some resources that can help you estimate fees when sending a bitcoin transaction, so you don't end up overpaying (or underpaying) unnecessarily. Keep in mind that in order to take advantage of this, you need a proper bitcoin wallet which allows for custom fee setting. A selection of such wallets you can find here
The order here is roughly from advanced to easy.
Here you can see a visualization of how many unconfirmed transactions are currently on the network, as well as how many were there in the past. Each coloured layer represents a different fee amount. F.ex the deep blue (lowest layer) are the 1sat/byte transactions, slightly brighter level above are the 2sat/byte transactions and so on.
The most interesting graph is the third one, which shows you the size of the current mempool in MB and the amount of transactions with different fee levels, which would compete with your transaction if you were to send it right now. This should help you estimating how high you need to set the fee (in sat/byte) in order to have it confirmed "soon". But this also should help you to see that even the 1sat/byte transactions get confirmed very regularly, especially on weekends and in the night periods, and that the spikes in the mempool are always temporary. For that you can switch to higher timeframes in the upper right corner, f.ex here is a 30 days view: https://jochen-hoenicke.de/queue/#0,30d
. You clearly can see that the mempool is cyclical and you can set a very low fee if you are not in hurry.
This is also an overview of the current mempool status, although less visual than the previous one. It shows you some important stats, like the mempool size, some basic stats of the recent blocks (tx fees, size etc). Most importantly, it makes a projection of how large you need to set your fees in sat/byte if you want your transaction to be included in the next block, or within the next two/three/four blocks. You can see this projection in the left upper corner (the blocks coloured in brown).
This is a simple estimation tool. It shows you the likelihood (in %) of a particular fee size (in sat/byte) to be confirmed within a particular timeframe (measured in hours). It is very simple to use, but the disadvantage is that it shows you estimates only for the next 24 hours. You probably will overpay by this method if your transaction is less time sensitive than that.
This is a very simple bot that tweets out fees projections every hour or so. It tells you how you need to set the fees in order to be confirmed within 1hou6hours/12hours/1day/3days/1week. Very simple to use.
Hopefully one of these tools will help you save fees for your next bitcoin transaction. Or at least help you understand that even with a very low fee setting your transaction will be confirmed sooner or later. Furthermore, I hope it makes you understand how important it is to use a wallet that allows you to set your own fees.
