Title: Let's add up the KNOWN lost bitcoins Post by: SgtSpike on May 04, 2011, 09:11:34 PM Thought this might make for an interesting thread...
If you've lost bitcoins (i.e. they're gone forever, completely unrecoverable), post how much you lost, and add it to the running tally. Right now, the running tally is 0BTC, since I haven't lost any bitcoins. I recently read a thread about someone losing 0.000001 BTC, and someone else losing 20 BTC. So person one would write: + 0.00001 BTC = 0.00001 BTC Person two would write: + 20 BTC = 20.0001 BTC Etc, etc. That way we don't have to run through pages and pages of thread to figure out what the running tally of lost bitcoins is. Make sense? Good. Do it. Starting lost BTC balance: 0.0000000 BTC Title: Re: Let's add up the KNOWN lost bitcoins Post by: kiba on May 04, 2011, 09:12:49 PM 0.00000000
Title: Re: Let's add up the KNOWN lost bitcoins Post by: gigabytecoin on May 04, 2011, 09:16:08 PM May have lost 0.05 BTC sent by the faucet...
Had it sent to a windows box, windows almost immediately received a virus, I simply removed the HD and re-installed ubuntu to a new drive. Time (and value of BTC) will tell if I ever boot up the old HD, remove the virus, and send my BTC back to the faucet/myself/anywhere. TL;DR I probably lost 0.05 BTC. Edit: I finally recovered them and have sent them back to the faucet! Enjoy, future bitcoiners! Title: Re: Let's add up the KNOWN lost bitcoins Post by: koin on May 05, 2011, 09:28:55 AM i'm sure there's a point to this.
i don't know if this counts, i can't log into mybitcoin are those coins considered lost as far as this thread cares? Title: Re: Let's add up the KNOWN lost bitcoins Post by: error on May 05, 2011, 12:41:03 PM Someone lost a Satoshi (0.00000001 BTC) the other day. Though I am told a miner got it in his transaction fees, so perhaps it isn't truly lost.

I don't think those coins should count... administrators of that site (present and future) would still be able to spend those coins. (i.e. They're still part of the total money supply). Title: Re: Let's add up the KNOWN lost bitcoins Post by: caveden on May 05, 2011, 12:45:40 PM A guy once lost 9.000 BTC by restoring a backup produced before a send transaction which had these 9.000 as input. That motivated Satoshi to implement the pool of addresses feature.

It was a generated block and I was messing around with switching wallets and I never backed that wallet up before it was deleted. A little mad at the time even more so now.

How did this happen? Shouldn't the block be invalid? Title: Re: Let's add up the KNOWN lost bitcoins Post by: Timo Y on May 05, 2011, 03:01:51 PM I have so many wallets lying around in so many different places, different computers, virtual machines, usb sticks, gmail attachments, mobile phones, that I have no idea how many bitcoins I actually "own" anymore. I might have forgotten about some of those wallets, who knows? One of these days when I have the time I should try to tidy it all up.
The only amount that I know for certain I've lost so far is 0.05 BTC back in Oct 2010.

To make absolutely sure that I was doing it on purpose, I set the reward value to 49.99999999, which meant that I inadvertently threw away the transaction fees which I could have allocated to myself. I did it as a tribute to our missing Satoshi: we are missing Satoshi, and now the blockchain is missing 1 Satoshi too, for all time. Before this, the total *awarded* ฿ would have been (assuming my calculations are correct): ฿20999999.97690000 Now, since I underpaid myself, the total *awarded* ฿ can only be: ฿20999999.97689999 --assuming everyone else pays themselves the maximum until the end of time. So, this is a provably missing amount of the fees+1 Satoshi from the blockchain, from block 124724, which appears to be 0.01 + 0.00000001 ฿. I did this by creating an option in my heavily customized client (derived from the git fork of bitcoind) which allows me to arbitrarily suspend the normal block reward calculation and underpay myself. The code itself only checks to ensure that I haven't *overpaid* myself. It doesn't at all care that I've *underpaid* myself. I view this as a freedom in the protocol, and not a drawback. blockexplorer.com has a display bug for that block which has not been corrected yet.

Then I rescaned the blockchain:
"balance" : 6848199.98999999, "blocks" : 136965, 50*136965 - 6848199.98999999 = 50.01000001 This isn't the same as lost coins— e.g. my client thinks it can spend the 1BitcoinEater coins. This is a count of coins that don't exist, at least as far as the wallet code is concerned. The 1e-8 is the coin midnightmagic opted not to generate in tribute to Satoshi. The 0.01 is the fee midnightmagic accidentally destroyed in the process. (http://blockexplorer.com/block/0000000000004c78956f8643262f3622acf22486b120421f893c0553702ba7b5) I'm _assuming_ the 50 is the duplicate coinbase from http://blockexplorer.com/block/00000000000a4d0a398161ffc163c503763b1f4360639393e0e4c8e300e0caec. These coins aren't even recoverable with a magical ECC cracking and/or hash colliding machine, but at least as far as the wallet code is concerned they're the only ones.

I sent to him and he lost due to software fail... Ok...Following that rate, when all 21.000.000 will be lost?! I mean, what is the actual "lost rate" of Bitcoins per day since its genesis? 38510.26334734 + 2.50000000 38512.76334734 Bitcoin's been going for what, 3 years now? But really only used heavily for 2. So you can assume around 19k lost coins per year, so far... Of course, there will never be "no more bitcoins". Losses are more likely to be expressed as a percentage of remaining coins, which would never reach 0. 19k out of 7M coins is about 0.27%. So a quarter of a percent of remaining coins per year. Who knows how that might change if Bitcoin becomes mainstream. On the one hand, more people touching coins = more lost coins. On the other hand, more people touching coins = more value per coin = fewer coins per person being touched. It might just even itself out.

I believe it is safe to say that the probability of a wallet's private key being lost is inversely proportional to the balance. We can model the expected loss over time as a Poisson process (http://en.wikipedia.org/wiki/Poisson_process), using the known data on lost Bitcoins to minimize the error. I'm no math expert however.

By default bitcoin kept users' currency in a digital "wallet" on their desktop, and when bitcoins were worth very little, easy to mine and possessed only by techies, that was sufficient. But once they became valuable, a PC felt inadequate. Some users protected bitcoins by creating multiple backups, encrypting and storing them on thumb drives, on forensically scrubbed virgin computers without internet connections, in the cloud, and on printouts stored in safe deposit boxes. But even some sophisticated early adopters had trouble keeping their bitcoins safe. Stefan Thomas had three copies of his wallet yet inadvertently managed to erase two of them and lose his password for the third. In a stroke, he lost about 7,000 bitcoins, at the time worth about $140,000. "I spent a week trying to recover it," he says. "It was pretty painful."

There is no such thing as LOST bitcoins. They are simply misplaced or UNSPENT. So unless you have the private key to SPEND them then they stay where they are. This is a security measure of course too.

Title: Re: Let's add up the KNOWN lost bitcoins Post by: jerfelix on February 06, 2013, 08:15:07 AM You have a spectrum of losses here, ranging from definitely lost to possibly lost. You are starting to cross into the territory where you can take some educated guesses at "possibly lost".
Not to totally derail this thread, but there was a thread last week that talked about the fact that the most popular amounts held in a Bitcoin Address are 1 satoshi and 50 BTC. If I recall correctly, there were 2 Million BTC held in Bitcoin Addresses with 50 BTC. Since 50 BTC almost certainly means that it was a mined coin with no transaction fees, then these must have been in the early days. This would definitely be something I would have done... hear about Bitcoin, download the client with the built-in miner. Run it for a few days, generate 50 Bitcoins, decide that was a worthless project and move on to the next idea. I'm sure other people did that back in early 2009 too. I would bet that the vast majority of 50 BTC accounts that are the result of CPU-based mining with no transaction fees are lost. I would bet that 15-20% of coins are lost permanently. Title: Re: Let's add up the KNOWN lost bitcoins Post by: dserrano5 on February 06, 2013, 07:11:40 PM That might be why the limit is 21 millions. Satoshi would expect 1 million coins to get lost, so the remaining coins in circulation would make a nice round number. Just saying.

I would actually totally expect instawallet to do that, since it's in their best interest to keep their hot wallet as small (and thus as small of a target) as possible, and accumulating lost coins only increases their risks, and thus costs.

There is no mention of a critical issue that could destroy all your coins on the Multibit website. Since when has this issue been known and what steps have been taken by the developers? Title: Re: Let's add up the KNOWN lost bitcoins Post by: lenny_ on March 16, 2013, 03:27:50 PM I discovered this bug in December 2012 but I didn't realize back then that my Bitcoins addresses are gone forever. I was discussing problems with sending Bitcoins from my wallet with Multibit main developer, jim618. But we both wasn't aware how serious this problem is, and my reported issue has been put away to his queue.
In February 2013 I checked again all my private keys and all adresses and realized that two private keys not match my Bitcoin addresses. Keys were for different address, but wallet still thought that they match and kept trying to do my transactions using wrong private keys, which was of course unsuccessful. Then I contacted Jim again, I sent him my wallet with some backups from past, but all of them contained wrong private keys and recovery failed completely. This is a really serious bug. Everytime you create new receiving address you should check it triple times on different wallets like Satoshi Client of Blockchain that private key match Bitcoins address - otherwise any payment sent to these addresses will be gone forever.

No. It would take longer than the life of the universe to accidentally generate an address with coins already in it.This is also assuming that RIPEMD is reversible.

Nevertheless: theft, loss or corruption of the wallet is an apparent problem which Bitcoin has to deal with in a better way. Especially when Bitcoin is growing and is becoming more and more common, which I expect everyone who likes it is looking for. An immediate idea I had is some kind of possibility to save a distributed encrypted version of your wallet in some kind of Bitcoin network cloud. Extend the Bitcoin protocol in a suitable way so that nodes can provide some amount of cloud storage. A wallet that goes into this distributed cloud storage is spread to a certain number of nodes and the Bitcoin network protocol has to take care that there are always enough "copies" available, so that restauration of a particular wallet is always possible. Only securely encrypted wallets are distributed to this Bitcoin wallet cloud storage. The wallet's owner only has to take care that he or she doesn't forget the encryption key/passphrase/whatever. The Bitcoin client should provide necessary assistance for this, like printout of keys or QR codes. I have not elaborated this idea any more, but I'm confident it could make wallet.dat wipes, harddisk failures/sudden deaths much less of a threat to your beloved Bitcoins. It's a pity and shame to permanently make them unspendable... Title: Re: Let's add up the KNOWN lost bitcoins Post by: SgtSpike on January 08, 2014, 07:34:59 PM I enjoyed reading this thread.

I think a torrent project along these lines could work well. Have a website where a user can upload an ENCRYPTED wallet file in any format (i.e., a user could encrypt it multiple times with multiple methods if they wanted), and the website would publish monthly torrents with a collection of all wallets uploaded to date. As long as at least a handful of people download and seed the collection, people would have a permanent distributed backup of their Bitcoin wallet.Nevertheless: theft, loss or corruption of the wallet is an apparent problem which Bitcoin has to deal with in a better way.

My full Bitcoin-qt client has to deal with the whoppy blockchain worth more than a dozen GB of storage (actually this sucks a bit). I wouldn't care if it asked me to use another 100 or 200 MB of storage space for the distributed wallet cloud storage. This could save quite a bunch of wallets. The majority of Bitcoin addicts needs some kind of Bitcoin client, thus he's connected to the Bitcoin network, connected to the fictitious distributed wallet cloud storage which every full client would support. Lots of wallets saved, no bits and bytes were harmed... ;D Title: Re: Let's add up the KNOWN lost bitcoins Post by: Rassah on January 10, 2014, 03:11:16 PM The idea of storing wallets in some sort of a distributed online fashion, where all you (or anyone else) need to remember is a password to access those coins, is really no different from just keeping your coins in a brainwallet with the private key derived from that password. The proble is that if anyone else guesses that password, they will have access to all your money as well.

Just think of all the potential suicides that would have resulted from these now catastrophic losses. Wow The poor guys who lost 7000+ and 27000 bitcoins...I wonder what they would be feeling right now if they haven't already killed themselves? If it were me, I'd still be around. I'm a tough guy. I've been through a LOT of hard shit - parents divorced when I was 9, I was sexually assaulted that same year, lost my mother to suicide 3 years later, endured years of school bullying, lost half of my sexual function from a bike riding accident, and when I was 23 my girlfriend who I was planning to marry had an abortion because her mother didn't want her to have the baby out of wedlock. So, at the end of the day - it's only money. If I had $8M or even $30M today I doubt I would ever recover the emotional losses that I have incurred. Remember, Kurt Cobain had millions and guess what he did in spite of his immense material wealth? He blew his brains out...

They bootstrapped their system by sending bitcoin to an unrecoverable address, some 2000 bitcoin in total: These bitcoins are lost forever because the chance of making up an address like that and then finding the private key for it is pretty much 0. https://blockchain.info/address/1CounterpartyXXXXXXXXXXXXXXXUWLpVr (https://blockchain.info/address/1CounterpartyXXXXXXXXXXXXXXXUWLpVr) Consider it a gift to the bitcoin community.

While it's doable, it's also very dangerous to those holding long-term bitcoin savings. What happens, for example, if I print out a bitcoin wallet, keep the private keys and public keys intact on a piece of paper, archive it in a safe, print multiple copies in different locations, in addition to keeping a dozen copies of a wallet file, and then 10 years later I want to redeem my bitcoin because it is worth millions of dollars. I load up a wallet so I can transfer them to an exchange...BUT the coins are gone. The blockchain had since been "audited and edited" and my bitcoin addresses, since they hadn't moved in 10 years, have been removed and the bitcoin re-minted to the miners. Ouch, that would be a very painful surprise. I think it's much better to just keep a log of all the known losses that are confirmed as absolutely unrecoverable, and then re-mint those bitcoins to the miners after 2 years since the loss, to avoid them being unspendable. But one point to remember is that lost bitcoin makes bitcoin even more valuable. If there are 1,000,000 bitcoins that are unspendable and out of circulation because of data losses, lost paper wallets, lost digital wallets, sent to non-functional address, etc, then the real number of available bitcoin will be probably less than 20,000,000. So, that would raise the price due to the greater scarcity.

Ouch, that would be a very painful surprise. I think it's much better to just keep a log of all the known losses that are confirmed as absolutely unrecoverable, and then re-mint those bitcoins to the miners after 2 years since the loss, to avoid them being unspendable. But one point to remember is that lost bitcoin makes bitcoin even more valuable. If there are 1,000,000 bitcoins that are unspendable and out of circulation because of data losses, lost paper wallets, lost digital wallets, sent to non-functional address, etc, then the real number of available bitcoin will be probably less than 20,000,000. So, that would raise the price due to the greater scarcity. Satoshi addressed this on June 21, 2010, 12:48:26 PM by saying: "Lost coins only make everyone else's coins worth slightly more. Think of it as a donation to everyone."

Title: Re: Let's add up the KNOWN lost bitcoins Post by: sssubito on February 18, 2014, 03:14:00 PM Not sure if this is still ongoing. I have lost 55 BTC that will never again be part of someones wealth. Are you sure your "lost" 55 BTC are truely lost in the terms of the OP? I'm asking because your signature speaks of lost coins due to a compromised mining pool. Have your coins been stolen or has someone lost control of your coins because the associated private key(s) are gone forever and there is definitely no way to recover them?It's important to remember that Bitcoins are never truely lost or destroyed or deleted in a technical sense. All you loose is the control to spend them should you ever loose the last copy of the private key of your various bitcoin addresses that hold some coins. Every minted Bitcoins lives happily in the blockchain. The question is: who has the private key necessary to spend them? Also, all of the coins from and in the genesis block wallet cannot be spent due to a quirk in the code. Couldn't this be corrected if necessary? I guess, Satoshi doesn't care much about those first coins...Title: Re: Let's add up the KNOWN lost bitcoins Post by: SgtSpike on February 18, 2014, 06:07:20 PM I wonder how many have been lost in faucets by people who give up trying to reach pay out #.

Title: Re: Let's add up the KNOWN lost bitcoins Post by: dowsey14 on February 20, 2014, 08:27:45 AM I just clicked back through the chain until I saw a 9000 -> 8999 + 1 transaction around the right date. But he could have bought a few more, because at that time they were pretty cheap. Still, a pretty nasty loss at the time. That was in 2010, if my memory of this thread serves me correctly. In 2010 bitcoins were trading for cents. For about $100, maybe $200 at most, he could have bought another 10,000 BTC. But if it were today, that would be just so unbelievably heartbreaking. Wish I'd known about bitcoin back in 2010, I'd have bought about 50,000-100,000 quite easily, for around $2000. Or...even better...in 2009 I would have been solo mining with Satoshi et al, and pulling in 1000s and 1000s of bitcoins without any trouble since it was just so easy to mine them back then. I spoke to one kid in America who pulled in about 6000 BTC in about 2-3 weeks back in 1st quarter 2009.

It's also pointless to dwell on it...like thinking about how much gold has been thrown away, lost, or destroyed since the beginning of it's collection. Knowing that a finite number of bitcoin will ever exist and understanding how much value people think bitcoin will be worth, do we all have a very serious duty to protect what we've mined, earned, or bought so as not to lose it? We're stewards of Satoshi's creation right? We shouldn't let it go to wast by forgetting wallets, losing keys, being careless - anyone else agree?

Title: Re: Let's add up the KNOWN lost bitcoins Post by: Mickeyb on September 07, 2015, 06:25:25 PM That 1% is a lot in my opinion, taking into consideration this is just a corner of the glacier, I guess there maybe in total 5% lost.. I wouldn't be surprised if it is more like 2M BTC lost. In the first year+ of Bitcoin's existence (during which almost 2M coins were mined) it was nothing more than an interesting experiment. The coins were worthless, and people treated them as such. I mean heck, the first known monetary valuation wasn't until Lazlo's pizza, which was mid-2010, 1 and a half years after it started. Not to mention than Satoshi himself mined a good 1M BTC, and I don't expect those will ever move.Just my best guess on it. I'd be willing to bet that 10 years from now, there will be at least 2M coins that haven't moved between now and then. Yes, all bunch of coins and the majority of them was lost in the beginning, when Bitcoin was still worthless. I agree on this with you. On the other side, 2 million lost coins is a quite high number in my honest opinion. I don't really know what to think about Satoshi coins. I like to think that he will wait until Bitcoin really makes it big and get mass adopted, and then he will donate 95% of his coins to the hungry people of the world. This would make him pretty much a biggest man on the planet that has ever lived. :) Title: Re: Let's add up the KNOWN lost bitcoins Post by: CohibAA on September 07, 2015, 07:21:54 PM phi bitcoins were burned in this transaction recently (https://tradeblock.com/bitcoin/tx/3e1572ca351d743d7bf627bc844da8f3bdc84eab4a9d27934a8dba30a2e05fe1)

If Satoshi did something good with his coins it could bring good publicity to Bitcoin to counter bad publicity like the Silk Road.

Title: Re: Let's add up the KNOWN lost bitcoins Post by: lixer on October 24, 2016, 06:42:03 PM When I was a newbie I lost 0.1 btc in doubler site as I thought I would be able to double my coins in few hours and from that point till today I am just waiting >:( It's something you have to forget about it, because if you're still waiting and angry against loss you get when early bitcoin then it will give bad effect to your future. because it is sure you will do something with very tight and could not think properly while doing something about bitcoin or associated with bitcoin Title: Re: Let's add up the KNOWN lost bitcoins Post by: DaveF on December 25, 2016, 06:22:53 PM Add 5 to the count. Was moving some coins back in 2011/12 (setting up them in lots of 5 per address) and had the dat file eat itself, was always a tomorrow project to get them back.
Sitting here Christmas day and figured I would fire up pywallet and have a go. Got 4 of the 5 private keys & addresses back. Last one does not even seem to exist. Sucks to be me. Good thing I wrote them off in my mind back in 2013 last time it was this high in value. -Dave Title: Re: Let's add up the KNOWN lost bitcoins Post by: merchantofzeny on December 25, 2016, 07:10:33 PM I never had a whole bitcoin before. I probably lost about 10000 satoshis from trying different faucets though. When I was starting out I didn't know they'd all require 20k something to be send to the wallet. I try to get up to that but would eventually give up and try a new faucet. And I tried many faucets I can't even remember them all now. I guess other newbies have gone through this, imagine how much has been lost in this manner.

They weren't added because these coins weren't lost. Someone has access to these coins and moved them. Title: Re: Let's add up the KNOWN lost bitcoins Post by: Xester on December 28, 2016, 12:58:01 AM How do we know that the counts are right and not just manufactured by the one who posted. Aside from the let us also not set aside that though they lost their bitcoins but somebody from the site has claimed it. But I dont want to be negative on this matter, I guess this counting was not meant to be exact but somehow just to check if there are more people experience losing their bitcoins.
Title: Re: Let's add up the KNOWN lost bitcoins Post by: ebliever on December 28, 2016, 03:08:31 AM A better way to lost bitcoins would be to list all the public keys involved, on a thread or blog or whatever. The list could be updated easily, including removing erroneous listings if coins did move from any of the listed addresses.
Someone with a bit of coding know-how could probably tie into an API with something like Blockchain.info and keep a running tally of all the BTC associated with the addresses in the list. One could also break it down into several sub-lists for clarity: 1. Known BURN addresses (like the Counterparty address). 2. Cases where it is pretty solid that the private keys have been lost (such as the early HD with 7500 BTC that was tossed). 3. Cases where coins are believed or claimed to be lost, but it is not confirmed or there is some slim chance of recovery. EDIT: Another reason to track this with the list of public keys involved is to avoid accidental repetition from multiple sources referencing the same lost bitcoins. Title: Re: Let's add up the KNOWN lost bitcoins Post by: coinplus on December 28, 2016, 08:26:45 AM Just a controversy perspective heads up here :
Bitcoins will never be lost. They will stay for ever within an address. There are only 2^160 possible bitcoin addresses (at least with respect to current encryption algorithm), so after (for example) 500 years, people may start getting OLD bitcoin addresses. At the time, they may find access to our lost bitcoins.

I am sure some of you have heard the story. it's no story, it happened and there is proof. but that is utterly not what this thread is about. he SPENT the 10,000 coins. he sent them to someone else, who still has them, or himself has spent them. you know, as one does with money. no loss occurred. this thread is about bitcoins that are GONE. that cannot EVER be recovered by anyone under any conditions. formatted the hard drive and lost your wallet file with no backups, that kind of thing.

More than 300'000 of them.
So if we add this to the numbers here, we can assume that about BTC450'000 have been lost that we know of. That's almost 3% of the available BTC as of today. Now what number of BTC is truly lost forever, I'd estimate is around 10% of the current supply. About 5 Billion Dollars worth of cryptocurrency.

Going on probably for another 2 million years to find a few collisions of private keys, in theory yes it is possible to recover all the lost Bitcoins But in reality the chance is practically near zero, unless of course if there was a solid proof and if the amount was really significant we could Have asked all the miners to do a hard fork in return to get paid something like %50 of the amount and the other half goes to the real owner.

Got it in 2011, forgot about it until BTC hit 3000 dollars. Spent hours trying to remember the dozen+ character password.

Doing that over a period might suggest what is lost and what fraction is normally forced back into the open after such a long time. yes, it's possible, even rather simple, to see what cans haven't been moved since a given time, or ever. the challenge is in determining WHY they haven't moved. it's entirely possible the original miner has them and still has ready access to the private keys, meaning they aren't remotely lost.

The value of that coin was too cheap of course and maybe you think that it was too high now but it is like a cents on the past. We also hope that we could back to the past and do captcha then save our private keys or some recoverable account. I don't lost anything because I can recover my account.

Spent hours trying to remember the dozen+ character password. Finally overwrote that drive to keep from going mad trying to remember the password as the price of BTC went up.

Title: Re: Let's add up the KNOWN lost bitcoins Post by: Liz D on July 10, 2018, 01:43:08 PM I couldn't follow the add up of the lost BTC on this thread but I lost a negligible amount of BTC of recent as well due to my stolen device. It amounts to 0.0003BTC ;D

Title: Re: Let's add up the KNOWN lost bitcoins Post by: requiredto on July 12, 2018, 09:24:10 AM I do not think the coins should count ... the site's administrator can spend those coins.
Title: Re: Let's add up the KNOWN lost bitcoins Post by: thefatman82 on July 12, 2018, 07:41:16 PM I have not lost anything. But I recently read information that officially lost about 3 million bitcoins are lost, i.e. in fact, only 14 million of the known 21 million are in circulation. I think they are even more.
Title: Re: Let's add up the KNOWN lost bitcoins Post by: lissandra3612 on July 15, 2018, 04:48:31 AM If it is sent to a windows box, the window almost immediately gets a virus, I simply remove the HD and reinstall ubuntu to a new drive. TL, DR I can lose 0.05 BTC. Enjoy, bitcoiners in the future! I may have forgotten some of those wallets, who knows?

I especially like the guy who spelled out the lyrics to the rickroll song. Its funny to read people in 2011/2012 kicking themselves for losing their bitcoin. I would imagine by today they either learned to let it go and live with it or have kicked holes in their heads.

If you still have the hard drive and it was a 'quick format', it's possible that you could recover the wallet.dat file and we can have a go at cracking it for you ;) Title: Re: Let's add up the KNOWN lost bitcoins Post by: Timelord2067 on March 07, 2021, 12:13:36 AM Our last annual tally of ~400 known "burn addresses", that is bitcoin addresses with almost assuredly no known private key, totaled 2,759.42507135 BTC as of Dec 2017. 2017 https://bitcoinwhoswho.com/blog/2017/12/30/8-97-bitcoins-burned-in-2017/ 2016 https://bitcoinwhoswho.com/blog/2016/12/21/btc-burn-addresses/ If those lists are accurate and the tally is as you say BTC 2759.42507135 then they will be worth https://youmeandbtc.com/bitcoin-converter-php.php?dir=frombtc&val=2759.42507135&cur=usd&btctype=btc&exchange=Bitstamp&dec=8&bgc=DDEEFF&txtc=111133 (https://youmeandbtc.com/bitcoin-converter) at the current rate of exchange to the US Dollar.

This is really good money 🤑💰!
For me, I have not lost Bitcoin before. Mine was when my account on an exchange was hacked and they stole my Bitcoin and when my blockchain.com account was also hacked too. My heart goes to you all that lost Bitcoin. Title: Re: Let's add up the KNOWN lost bitcoins Post by: DARK92 on January 30, 2024, 02:41:45 PM Back in late 2009, I bought 1000 from NewLibertyStandard for about $1. Not long after I formatted my hard drive and didn't bother with them saving them... Yeah I know. What an idiot. +1000 welcome to the idiot club then because I only bought 1400 for 105 dollars and I left them on your bitcoin market site! unless you want to give them back to me! that would be really very nice! after 15 years! but I've been trying to contact you for 3 years! Have the aliens released you? Title: Re: Let's add up the KNOWN lost bitcoins Post by: bolshojkush on February 04, 2024, 04:08:06 PM Got it in 2011, forgot about it until BTC hit 3000 dollars. Spent hours trying to remember the dozen+ character password. Finally overwrote that drive to keep from going mad trying to remember the password as the price of BTC went up. I think this is the most idiotic decision. The password can be chosen 100%, especially now that there are quantum computers. Here, of course, the amount on the account decides.

But I recently read information that officially lost about 3 million bitcoins are lost, i.e. in fact, only 14 million of the known 21 million are in circulation. I think they are even more. What’s the worst thing that could happen anyway,Well, we hate to say this, but there may be a chance that you won’t be able to see your old Bitcoin and the funds inside it—ever again. According to Cane Island Digital Research, about 4% of available Bitcoins are lost each year. |
