Or another question!

Is there a place to collect the lost bitcoins (I mean the private keys is lost,and the bitcoin in that special address stay there forever) :D

However it is interesting for all bitcoiners.

I have 10 lost ,I lost them in 2011.the price in that year is less than $1😄

And you?

There's no special place where lost bitcoin can be collected or retrieved other than the use of the very wallet private keys and if the private keys (seed phrase) is lost then your bitcoin in that wallet is lost forever and better be forgotten.
That is why we are advise to safely secure and store or private keys to avoid losing our coins .

Fortunately, I haven't lost my Bitcoins permanently, but I did lose some funds from trading. Detecting the exact number of Bitcoins lost forever is challenging. Some sources identify Bitcoins that haven't moved for a long time, but that doesn't necessarily mean they are lost forever. There's no way to collect missing Bitcoin addresses or private keys from any sources. It's not a practical question, as finding private keys would mean the Bitcoins aren't considered lost.

Sorry to hear about your losses. This is really huge in current price. You should forget them and move on.
There is no way to know about how many Bitcoin disappear forever. To mean it I will say that they don't disappeared but their access have been lost. But if you send to a wrong address it will still show in Blockchain but you will have no way to access it.

And there is no way or any solution to retrieve lost Bitcoins and no one can access his Bitcoin without Seed Phrase or a Private key. So when you have forgotten or lost your backup that means you lost if forever and no one will be able to retrieve it. That's why we must secure our backups to a safest place.

I lost some Bitcoin by sending it to a wrong address which is really hard to accept. I will advise to recheck your sending address several times and do it seriously when making a transection.

There is no way to find how many bitcoins are lost forever. Very often we see Bitcoins that are sleeping in wallets for years are moved. So if coins are sleeping or not moved even then we cant say that they are lost forever. But there is consent that there is huge number of bitcoins that are gone forever. Its because in early days people took Bitcoin for-granted and didnt cared much about there Bitcoin's when its price was under 1$.

The supply of bitcoin is immutable, so no bitcoins are actually lost or deleted forever as you are trying to put it. Only kicked out of circulation through people losing access to their cryptocurrencies and all that. There's a possibility for these people to access these coins once again and sell them which will drive the price of bitcoin lower but at the same time it's a little improbable especially in cases where it's saved on self-custodial wallets. Sorry to hear about you losing out on so much bitcoin. If I'm not mistaken and if you still have the drive where you saved those bitcoins, certain programs and companies are out there with the sole purpose of providing assistance in regaining access to your bitcoins so you can get them back although not really sure about the authenticity of these entities. Still worth a try especially if you're getting desperate.  

There is no way to steal people's BTC if you don't have their keys, you can only prove ownership of BTC if you have the private keys; if there was a way the network allowed people steal BTC's that don't belong to them, then BTC would have been dead by now.

There is no way to know that BTC in an address is lost, even if the funds have not moved for a very long time, it could be that the owner of the funds is a long term holder. There have been too many posts of late about lost BTC and how to recover or collect them like this op said, lost BTC are lost and they reduce the circulating supply and make your coins and mine worth a little more.

this is why it is said those are lost forever. so it means forever, and not recoverable at any given point. if you don't have the keys, you can't possibly get it back.
and that number, no one even the experts know how much was lost. we can't determine as we don't know how many forgot to recover their coins, or how many of those addresses will remain untouched.

Whoops, sorry about the missing Bitcoins. These are the breaks that you've got to take

So, to address that, let me say this. Measurement of Bitcoins Misplaced... Quite the test! Especially considering that the blockchain itself lacks a "Lost & Found" counter! The truth is, you can either laugh or cry about it. If you forget your private key, your Bitcoins will disappear like socks in the dryer.

Wow, you managed to lose ten Bitcoins back in 2011! Lets not go there, buddy. It's just not worth the pain. And me? I guess Im cautious; I havent misplaced any of mine. Knock on wood!

Not your keys, not your coins.

Your private keys or seed phrase are proves that you own the Bitcoin in a wallet and if you don't have it then you're not the owner. If you lost your private keys or seed phrase, there's no way to recover your bitcoin, for it is gone forever. Move on and learn from your mistake. Next time, write it down on a clear piece of paper and keep it somewhere safe, you can keep it in more than one locations. Also, you can use a metallic steel to write down your seed phrase.

I don't know which site can identify lost bitcoins (not moving) but so far I haven't found that, but someone else might know.

By 10 BTC do you mean you lost in 2011? That's $290K at current prices, but do you still remember the wallet it was in?

I've never lost bitcoins because the private key was lost, always make a backup copy to keep the private key so it's really safe.

ITB (IntoTheBlock) is one of the analysts who stated about the research of counting how much BTC lost. They claimed we probably already lost around 29% of BTC. But it is concluded from no movement on those BTC, they haven't moved for many years. Not sure whether the approach is accurate enough, they only analyzed it on 1 factor only.

Take a look here https://cryptopotato.com/this-is-how-much-bitcoin-btc-has-been-lost-forever-itb-data/

10 lost? Do you mean 10 BTC or lost it 10 times?
It is very unfortunate, but it gives you a big lesson, right?  :)

I never lost any BTC so far. I have learned a lot about how to keep it in a safe way. I hope I will never experience to lose any of my BTC.  :)

According to my understanding, if you lost your private key, your bitcoin is gone forever this because no one can be able to spend the bitcoin in the wallet unless if someone has access to the private key.

Hard luck for your bitcoin lost.

I recently stumbled upon a Google search, and it caught my attention that newsbtc released a report stating that Six Million BTC Are Out Of Circulation Forever (https://www.newsbtc.com/news/bitcoin/six-million-bitcoin-now-lost-forever-why-this-matters/amp/). This suggests that if their report is accurate, six million Bitcoin have been lost. However, I personally think the actual number might be higher, though I cannot confirm the accuracy of the report. It's possible that some of these "out of circulation" Bitcoins could resurface in the future as their owners may be holding them long-term.

Their report cannot be accurate, it is just an estimation like every other estimations about lost BTC, there cannot be an accurate report on the number of lost BTC's, because it is not possible to know the exact number that is lost.
That can possibly happen, it is common practice for people to think that BTC's is lost if it hasn't moved from an address for a very long time, when the owner may just be holding it for the long term.

As we lost our keys, we can no longer get our Bitcoin back. As many people become careless with their keys/password, more lost Bitcoins will be added to the circulation but there is no tool that it counts how many Bitcoin is in there. Reports can be delayed and so the recording but it was not important because even though we know how many, we can never take it back and be included in the number that we can avail in the market. To sad to say that we have to move on and forget those lost Bitcoin and learn from the mistakes that we made in the past so it won't happen again.

I know lots of bitcoin have been lost, some people that bought bitcoin at the early stage already lost access to their wallet because they didn’t expect bitcoin to be great, so they were not serious with the bitcoin they had then, but theirs know way to know the amount of bitcoin that have been lost, a wallet might be inactive for a long period of time those not mean the owner already loses access to the wallet, the owner might just decide to hold the bitcoin for a long period of that that’s why the wallet is inactive, so it’s really going to be difficult to know the amount of bitcoin that have been lost.

I haven’t lost any bitcoin, and am carefully protecting the bitcoin am having currently, my private key is secure in a place where no one can easily have access to it, and it’s stored offline, so that no hacker will be able to compromise my account and have access to it.

If we completely lost our access to the private key and seed phrases then I do not think there is a way to recover them.  With that the BTC held on that wallet will also lost forever.  I do not know any method to recover the completely lost private key and seed phrases that is why we should take care of our Bitcoin holdings seriously.
An estimation is never an accurate data. It is a guess on a certain range so it does not accurately tell how many BTC were lost over the course of these years.  So I agree that it is not accurate.

No! Nothing suggests that their report is accurate. Even in the tweet they shared, Timothy Peterson stated: "I estimate that..." This indicates that it's just an estimate, and nothing more.
Even if you read the entire article in the link that Mr. Peterson shared, you will see that there is no concrete evidence of lost coins; rather, they used a specific methodology to estimate the amount of lost coins. There's no way to know if their methodology is even remotely accurate.


Based on what?

That’s a lot of bitcoins, so sorry for your loss. I hope that’s not all you had, it will be comforting if you had some bitcoins stored in a different wallet. 2011 was a different time and people were not as cautious of their bitcoin as they are now because of the price value.
There is no way to recover lost bitcoins, I have read articles online about softwares that generate thousands of private keys that may or may not contain some lost bitcoins, there has been no record of success and I don’t think anyone should waste his time on such treasure hunt.

2011 is a long time from now and there is now way you can recover your Bitcoin. Once you lost your private key, just forget about your entire Bitcoin portfolio because you will not be able to recover them. This is one of the reasons why we need to keep our private key safe form external access because anybody that lays his hand on the private key can transfer all the whole Bitcoin in that wallet and it can't be recovered again. There are many investors too that had made this kind of mistake and till now they are still regretting it how they were so unfortunate to have lost access to there private keys.

Bitcoin wallet is decentralized and nobody or any other person has the access to your wallet so if you lost your private key then your coins will lost forever and that is why we advise bitcoin users to always have backup of the private key and split it in different places so in case you misplaced the one that is with you, you can still use the backup to retrieve the wallet back. The amount of bitcoin you lost as of that time was not big as of now. But what really happened that you lost such amount of bitcoin. Probably as of that time you were not serious about the coins if not the whole 10 BTC just lost like that? Op your negligence might had caused this. Sorry.

I think its kind of impossible to really come to terms with the exact number of bitcoins that are lost, this is because, when we visit the bitcoin blockchain explorer, and view addresses holding bitcoins, there is nothing indicating addresses holding bitcoin that their respective owners have lost access to, they appear there like every other address normally.
Chainanalysis and other forensic experts might or do come up with some numbers as possible bitcoin that are lost forever, but the truth is that, we can never be sure, since most of the time, those numbers are called from wallet holding bitcoin that haven't had any activity on it for a very long time, that is not an evidence enough that the owner of such wallet have lost access to it.

Well, there is no such place, lost bitcoins are lost, except the user luckily discovers or recovers his or her private key, that is, the key to the wallet containing the bitcoin, anything outside that, there is no other way to get lost bitcoins back, if there was, then the lost bitcoins will not be referred to as lost - in the first place.

I'm sorry for your loss; I'm guessing you tried recovering them already to no avail, which is saddening, but you're certainly not the only one.

This matter has been discussed quite a few times in the past. An exact amount of lost Bitcoins can't be determined, but as others have already mentioned, it's said to be approximately 5 to 6 million coins. Of course, this estimate might be way off, but there's no actual way of knowing. The intriguing part of this is that Bitcoin is actually rarer than we've thought it to be due to its actual circulating supply, which is a lot smaller than the current number of approximately 19.5 million coins.

There's no way anyone can get those lost Bitcoins unless the private keys to the wallet that contain the BTC are retrieved if it's not retrieved the BTC is lost forever.
To your question, it's hard to know all the BTC that are lost forever but as of November 2022, it is estimated that 2,550,615 bitcoins. (https://www.hedgewithcrypto.com/how-much-bitcoin-is-lost/)

I am sorry for your loss and you're not the only one who is the early holder of Bitcoin but lost along the way. Although, I have never join the BTC scheme then but years ago I got some SOL through Airdrop but didn't withdraw it from their Airdrop website and that's how I learn the lesson of never any crypto.

That was a long time ago. By the time you lost Bitcoin, you should immediately find the key to open the wallet. You can check all the places where you usually put your important things. There is a very low chance to found a lost Bitcoin private key if takes a decade before you decide to find it. Most of the time, the things that are visible in your house are not visible in today.
It's a lesson to us that we should keep our private key in a safe place, if possible in multiple places. If ever you can't find it, the chances of finding them increases and you should change your private key after you found it.

As of this moment, there isn't any way to retrieve those 2,550,615 bitcoins (rough estimation), but who knows. We might see a device, or something that has the capabilities to retrieve it though I don't know how, but with how the technology is evolving right now, and on a rapid pace we might have one in the future.

As for me, I guess it's good also that when I first started to invest into Bitcoin, I saw many people using it already, and it's starting to become popular at that time. Those early adopters of Bitcoin who bought very early like you (if it's true), have a tendency to just forgot it back then because you don't know what will it be 3 or 5 or even 10 years from now. Well, 10 Bitcoin is already a huge compare to what it was when you bought it, but I guess it's time to say goodbye to it unless you remember where you stored your private keys. :)

With this, I remembered the person who threw away on the dumpsite his floppy disk something or a hard drive that contain private keys that hold thousands of Bitcoins. :D

Not lost but just lose in trading.

Those lost forever can't be retrieved if there's no longer the private keys from the owners of it. @OP how did you lost that 10 bitcoins of yours?

And that's sad as just this one: The Welshman who accidentally threw out 8,000 Bitcoin in 2013 is mounting an $11 million campaign to get it back (https://fortune.com/2022/08/01/he-lost-8000-bitcoin-launching-11-million-dollar-campaign-newport-james-howells-landfill-trash/)

Maybe you still haven't figured out what Bitcoin is. Bitcoin is a blockchain based decentralized currency which allows you to be your own bank.
Any bitcoin in any wallet will remain there unless it's moved by the actual owner or you give your private keys to someone.

Bitcoin does not disappear, it just stays in the account. You cannot destroy Bitcoin, it can only be transferred from one account to another.
And the amount of "lost" bitcoins, maybe you mean the accounts which no one can access now, cannot be calculated however you can check which accounts are inactive for maybe 10 years?

Access to wallets and bitcoins can be changed hands, recovered by some future advanced recovery services or compromised, we don't know about it now. We only assume very long inactive bitcoins have high chances of belong to people who lost access to those wallets and bitcoins.

We only can use HODL waves (https://www.lookintobitcoin.com/charts/hodl-waves/) for estimations which are only estimations and don't represent exact amount of forever lost bitcoins.

We can use 10 years like you suggested, 8 years, 6 years or 5 years, any period that arbitrarily chosen by each person. Not all bitcoins inactive for like last 10 years are lost bitcoins and those coins can be woken up anytime in future.

From the information I know, the missing bitcoins to date are quite large.

That way, if the original owner doesn't remember or doesn't find the private key of the bitcoin in his possession, then the bitcoin will surely remain lost forever. Even to be hacked it would be very difficult, even very impossible to do.

So if you have lost your bitcoins, try to remember where your wallet keys were and you wrote them down. Is it written on paper or you save it in the computer. If after doing this and you don't remember your bitcoin wallet key at all, or you don't write down the phrase at all. That means you have to be able to give up the bitcoin that you have.

Therefore, if you want to buy bitcoin and store it in a non-custodial personal wallet. Don't forget to copy the key/phrase, and keep it in a safe place. That way, the key won't be lost and your bitcoins will stay safe.

I had to double check the date but there is a thread EXACTLY like this somewhere on bitcointalk where people discuss how many bitcoins they lost forever and they kept a tally. I am too lazy to search but I remember reading it a few times. Maybe someone here knows what I am talking about and can post it.

As for coins lost? I would say around 2 million or so for sure. Maybe up to 4 million in some cases. The satoshi coins are definitely lost and there is over 1 million or so plus another million or two for people who just lost their private keys.

Some of those six million worth of bitcoin could have been lost owing to sudden death of the owners maybe a ghastly car accident or some related accident (not only through a lost of private keys by owner) ,and these unfortunate BTC owners in their wallet never exposed their private keys to a trusted family member who could have been able to have access to their wallet to retrieve those BTC from eternal loss.

What can we make of this in relation to increasing clamour for BTC hodlers to keep their private keys completely secret from anyone  not even to family members (under the idea of keeping it safe) due to trust issues.  Accessing this what are the options to avoid forever loss of our BTC if we don't want to let any family member know about our private keys while we're still alive?

There's no way to restore access to coins that were truly lost, and it's also next to impossible to assess which coins fall under that category. Estimations usually rely on presuming coins that weren't moved for x years are lost. But it's perfectly reasonable that some may simply have no reason to move the coins over the years while technically being able to do that, so those coins aren't actually lost. Then there are people who lost access to their wallets, but there's a small chance that they or someone else will find access to them at some point by stumbling upon a seed phrase or something. Finally, there are coins that were burned intentionally and those accidentally sent to non-existent addresses, in which cases the coins are truly lost, but keeping track of that isn't easy either.

You should keep the private keys (magic numbers) to your Bitcoins closely guarded. But what if you're chilling and then you're not and all your satoshis vanish in a puff of smoke?

After some pondering, I think I've come up with a few potential solutions to this problem. Have you heard of these so-called "dead man's switches"? If you dont answer to their periodic pings, they'll leak your confidential information. However, you should know that putting it together can take some doing.

You may even utilise a time-locked transaction and go all-out Mission Impossible on them. Your Bitcoins will be sent to a verified address at the specified interval. But you should exercise caution. Too lengthy of a timer and you'll be racing against your own money.

The only bitcoins that we can classify under lost category is that sent to OP_RETURN command otherwise people who have lost keys or passwords to their wallets may at some point recover those and coins will again be in circulation so we can't call them lost.Although they are lost in the current time and out of circulation but in future we may see supply boosted if they get access to it.

There are many articles claiming around 4M coins are lost but we don't have access to any data that make clarifications on this matter so we just assume they are lost at this time.

I do not think that it is possible to pinpoint which wallets have lost private keys unless you specifically know them.

As far as I know, there are thousands of BTCs which are currently lost in circulation or inside some wallets that belong to either deceased persons who have failed to share their private keys; or to some people who completely forgotten about them. Though this may be the case, I do believe that this is what makes the economy of BTC- its limited resource and scarce supply makes it more valuable the more it is being mined.

This is also the reason on why many anticipate the upcoming fork this 2024. With this being said, I do recommend that you always keep your private key to yourself or inside a vault in the event of an accident to your life or to your belongings.

Well, as Bitcoin is constructed to be trustless and decentralized, there's no central entity to keep track of "lost" bitcoins. There are provably destroyed coins, those you send to OP_RETURN outputs, miners not claiming the full allowed block subsidy (yes, that happened in the past, unlikely in the future) or spend scripts that can't provably ever be fulfilled.

Then there are "burn addresses" like 1CounterpartyXXXXXXXXXXXXXXXUWLpVr (213,098,332,861 Sats locked), 1ChancecoinXXXXXXXXXXXXXXXXXZELUFD (48,019,569,938 Sats locked) and 1BitcoinEaterAddressDontSendf59kuE (1,331,866,970 Sats locked), to name a few, where it is almost certain that no entity has the public key and private key. Coins sent to such addresses are taken out of circulation and fill up the UTXO set. They are to be considered lost because no entity will ever obtain the private key for such addresses.

Then with some effort to search in this forum you could've found topics like this one: Let's add up the KNOWN lost bitcoins (https://bitcointalk.org/index.php?topic=7253)

You can't really prove what users have listed there but it adds up to some thousands of likely forever lost bitcoins.


I had some really small amount of Sats from a faucet in 2011 that I stacked in a separate Bitcoin-GUI wallet, maybe a few or tens of mBTC, and I'm not sure what happened with those. I thought, I transfered them to my main wallet back then, but couldn't find the incoming transaction in my oldest wallet(s). So, maybe those are lost, unless I dig up that wallet from somewhere deep hidden in my filestore. I've no high hopes, though.
