Title: How many BTC is in circulation?
Post by: RapTarX on February 10, 2019, 04:47:25 PM
From Coinmarketcap, there are 17,530,775 BTC available in circulation. But what is the actual amount excluding the lost BTC? How much BTC have been lost until now? Is there any reported/proofed list of lost BTC amount/addresses?

I managed to find this (https://fortunedotcom.files.wordpress.com/2017/11/lost_bitcoins.png) but I would say It's probably far from being accurate because losses are not always reported, and you can't really make the difference between a wallet not being touched in purpose (hodling) or a wallet that has funds that can be accessed anymore.

I've searched for the same articles and most of them says that it was around 4 million bitcoins.

This latest article said around 20%  of bitcoin's supply --> https://www.newsbtc.com/2019/01/10/bitcoin-supply-lost-forever/

We cannot know the exact number of bitcoins that have been lost or not in circulation, but we can estimate from the total supply and circulating in the coinmarketcap. Thank you.

The only ones we can be 100% certain of are those sent to burn addresses which is a few thousand. Beyond that we have to take everyone's word for the others.

I don't buy these figures of 20-25% of the supply being lost. I'm sure it's plenty. I'm also sure there are many coins that haven't moved for several years that are fully accessible. For some reason not moving for a while is enough for others to declare them lost.

It is impossible to know the exact figures of lost bitcoins, you would get estimates if you search it up, but they would be off and likely inaccurate.
Not all losses are reported. Some lost coins could be recovered in the future.
You can only go with the reported cases of lost bitcoins

i guess there's only so much analysis you can do on a public ledger. at some point, it becomes a guessing game.

20-25% definitely sound like an overstatement, but honestly it sounds possible a couple decades from now. we're still at a stage when users are largely not securing coins properly. after every bear cycle ends and a new bull cycle begins, i feel like lots of old investors come back to find their coins are lost. that's easy to do after a multi-year bear when you thought bitcoin was dead---forget a password, reformat a computer, chuck out that old hard drive that's on the fritz anyway. like this guy: https://www.independent.co.uk/life-style/gadgets-and-tech/news/bitcoin-value-james-howells-newport-landfill-hard-drive-campbell

Even if there wasn't any lost 21 million is a small amount considering the demand that is going to follow as it goes mainstream. 1 million is locked by satoshi, and a few million lost when it was worthless. 4 million sounds about right for number of unclaimable bitcoins

There's no way to figure out how many Bitcoins are still in circulation and how many are lost or stuck on an address that are non accessible anymore. In this article https://www.ccn.com/6-million-bitcoin-is-lost-or-stolen-should-the-real-value-of-btc-higher it says that there are 4 million lost and 2 million stolen Bitcoins but I doubt that this is accurate because there's no possible way to to accurately know the amount of Bitcoins that are stuck forever, and not all lost and stolen Bitcoin are being reported on news or being featured on articles. Also we cannot conclude that Bitcoins are lost if it hasn't been moved from an address to another for a very long time.

A wallet that is rarely processed and a lost wallet cannot be fully distinguished, so they may be hesitant to say something about it. I don't think anyone has a clue about the number of lost wallets.


Title: Re: How many BTC is in circulation?
Post by: miropp on February 10, 2019, 09:21:19 PM
If we consider lost wallets for which there was no transaction since the first serious growth of the exchange rate (01.03.2013), then in total these wallets contain about 3 million bitcoins. This is important to consider when assessing the situation in the market: actually in circulation at the moment is about 14 million bitcoins to 7 milliard people population, not 17 million, as they say on the crypto-exchanges. But this cant be considered reliable data. The exact number of lost bitcoins no one knows.

I remember Jameson Lopp (of statoshi.info) said he did a study on this and came to similar numbers as Chainalysis.

I don't buy these figures of 20-25% of the supply being lost.

It's worth noting that Chainalysis put the estimate at 2.78 million - 3.79 million. "Nearly 4 million" is what made the headlines. They also included the early "Satoshi" coins in those numbers, which they estimate = about 1 million bitcoins.

If we take the low end and table the Satoshi discussion, that's around 10%.

What was their criteria beyond the coins not having moved? Beyond burner addresses and publicly known events like that Polish exchange that deleted its private keys that's all they have to go own in most cases. I've got coins that haven't moved for over five years. They certainly ain't lost.

apart from the young man who said his girlfriend threw away his hard drive containing about seven thousand five hundred encrypted bitcoin there has not been anyone i know of in the world or the media space i know that has complained of missing bitcoin in any part of the world. so i will say the total bitcoin in circulation is actually the current total minus the missing 7500 that is missing.

You're correct, there is no actual proof or evidence about those lost Bitcoins that are stagnant in an untouched wallet and no one knows the actual number of lost Bitcoins in wallets, people just calculate it with any data that they gather and it is not accurate. Even if we get the information about the exact amount of those lost Bitcoins in wallets there is no way to recover it and it will still be lost forever.

have you ever moved the bcash or other forks associated with your keys? apparently they mined a lot of data from that: (http://fortune.com/2017/11/25/lost-bitcoins/)

Quote
Chainalysis’s overall methodology is confidential, but a spokesperson shared certain details about how the company assesses which bitcoins are lost. An important clue comes when there is a “fork” in the blockchain, such as the one this summer which led to the creation of a bitcoin clone known as Bitcoin Cash. Such events can lead to the owners of wallets that have been inactive for years to conduct a transaction, providing an opportunity for statistical analysis.

These sort of clues help inform the Chainalysis figure for the “hodler” category—wallets belonging to people who got into bitcoin before it hit the big time, and which represent the biggest source of uncertainty as to whether bitcoins are lost or just being hoarded.

they also mention "scraping the Internet for reports of lost coins" and things like that. logically, there should be some model to account for death and things like that too, but i don't know how they'd begin building it.

of course not, we never know the exact number is missing, the blockchain only records everything in the chain, but it seems that it doesn't record when someone loses bitcoin because of forgetting passwords, private keys, system market errors or stolen balances, then the bitcoin remains in the blockchain, just move wallet or even just stay in the same wallet. If at this time many do research, they only have approximate numbers, not the right number.

I found an article while I was completing my homework, author mentioned almost a total of 3380582 bitcoin was never touched since the its first transaction. He created a spreadsheet as well- https://www.reddit.com/r/Bitcoin/comments/2twrs7/all_42400_dormant_bitcoin_addresses_with_a/

Of the 21 million bitcoins, about 16.74 million (or 80%) are in circulation, and the rest are still to be excavated by miners. The miners'mined money can be traded on the Exchange of Currency Digital Money. So far, four million bitcoins have been left in one corner.

Don't think anyone can answer this question surely because not all losses reported but we know many wallets lost, anyway, we have only 21.000.000 max supply  which is very low and if every millionaire would buy one btc then most of them cant do it because we have much more millionaires than the maximum supply of BTC.

At least we get more knowledge, a lot of information that we can get in this thread and can be used as experience.

I have visited the link you shared, I have read everything, all the information that I can not conclude the wallets part of the lost bitcoin, it's true that the wallet was not touched for a long time, no suspicious activity. it may be that the owner loses access, but there is still a possibility that he indeed saves.

you are right, I strongly agree. and do not know who to report to. while the research carried out is only based on inactive wallets with a large amount of balance. I have experienced a failed transaction sending bitcoin, the number of transactions is only 0.008btc, shipping from wallet exchange to the blockchain, I have tried reporting to the exchange, the problem has not been resolved, and not only I have experienced, I am sure there are a lot of users which might be much smaller. and that will not be recorded in expert research data.

       It is very difficult to predict because not always the losses of BTC are reported. So there is no way to fire Bitcoin if they were not counted anywhere. There are a lot of platforms, probably who lost Bitcoin because they forgot their passwords or technical motions. These Bitcoins can not be counted anywhere. However, the subject is very interesting!

AFAIK, that lost Bitcoin will be mine by those miners. So if ever there's an amount or certain loses it will recover by the mining process.
Exactly, we don't know what the exact amount of lost Bitcoin. But why we would worry about that as long as we have something to hold you'll be fine.

That's interesting. I'm not sure why that never dawned on me. When Bitcoin Cash forked, people started sweeping keys to recover and sell the coins. Unless those sweeps were done extremely carefully, the hard forks probably handed Chainalysis an incredible amount of address clusters and transaction history on a silver platter!

On top of risking malware, people take big privacy risks to recover hard forked coins.

There is no right statistics on how much bitcoin have been lost and it only when we have that we can state how much bitcoin is in circulation's. But the initial amount of bitcoin in circulation's both the ones stolen or lost is 21 million bitcoin.

Post by: CryptopreneurBrainboss on February 11, 2019, 09:41:16 PM
Neither Coinmarketcap or Satoshi himself can tell you the actual amount of Bitcoin in circulation although the only stats they know and it's universally known is Bitcoin has a total supply of 21million coins.
Along the 10 successful years of Bitcoin existence, there have been case of early adopters losing their Bitcoin because they either forget password or private key to their wallet and we have also seen cases of stolen or hack Bitcoin etc therefore the actual circulating supply of Bitcoin can't be stated because it will just be an assumption.

There are no exact figures. But I read somewhere that there are about 14 million bitcoins in circulation. But this is not accurate data because we do not know the exact number of bitcoins lost.

Yup. We need to find the number of INACTIVE bitcoin accounts and count the bitcoins inside.

You can't mine Bitcoins that already been mined one time before, there's no double spending in bitcoin. Lost bitcoins are truly lost.
 However it would be an idea if  miners in 25 or 30 years from now when the block reward starting to be very low,  was allowed to be payed from dead bitcoins, a dead bitcoin tax of around 0.01 or even less a year, on bitcoin that havn't been moved since 2009, would be an idea to pay for the worlds biggest blockchain, this would keep the blockchain alive and keep the transactions fees low.

Correct me if i'm wrong.but think there is now way that we will know of how much Bitcoin have been loss and exactly circulated unless if there is independent group or organizations that will do this kind of monitoring activities but still it is difficult job as we are millions of users worlwide. Unlike fiat that they have a Central Banks that will audit there money but there is none for Bitcoin currency specially that it was a centralized in nature.

Theres no accurate number on how much was the total amount, there were initial calculation only but I think it wasnt as close as the real amount. Cases like loss doesnt always have reports. What is important, is we still have huge amount in the circulation today as we close to mine all Bitcoin.

Your question is not simple. And it may actually contain several correct answers. It is necessary to create some arbitrary parameters. For example:
  • Consider as in circulation only the bitcoins that were moved after BCash's fork.
  • To consider as circulation only the quantity of Bitcoins in addresses that have been opened or moved in the last 4 years.
  • Consider as in circulation any address that has been used more than once, that is. It would exclude those that were used by miners in the beginning.
