Let's add up the KNOWN lost bitcoins

[SgtSpike]

Do we include this?

My developer friend was paid 500 bit coin for a $200 project by some Russians a few years ago. He took then off the exchange and forgot about them. A year ago, he gave his mac to his brother. Because of the bitcoin craze of the past month, he checked his old computer. It has been completely reformatted and replaced with Windows. $45,000 gone, just like that.

May as well...

If I was some of these people who lost coins, I'd be looking into some serious forensic data recovery at this point.  Or at least selling the drives to someone who has the capital to risk in attempting it.  $45k is no laughing matter...

I lost a wallet with 88 btc in 2011.

[conspirosphere.tk]

I sent a total of 25 BTC to an address that I was convinced to own in one of my wallets to keep them safe.
Now I realized that that address is in none of my wallets  

edit: I found that wallet again in an old redundant backup! whew!

I think I lost 0.1 a while ago.

What happened is my Bitcoin-Qt client completely died on me, and wouldn't open. I had 1.1 Bitcoins in my wallet at the time. In the end I transferred it to an online wallet using the wallet.dat file but only managed to recover the bitcoin, and not the .1. Guess it's lost forever now.

So yeah, +0.1

+1.3 - Blockchain wallet hacked

+1.3 - Blockchain wallet hacked

That's not lost Bitcoins - they are still accessible by someone.

I lost 78 bitcoins when I encrypted my wallet and mistyped my password.

Well, that can't be too hard to re-create, no?

I lost 78 bitcoins when I encrypted my wallet and mistyped my password.

If you remember anything about the format of the password, then there are a number of scripts in these forums to help you figure out what it was.  Specifically, the Development and Technical Discussion board.  PM me if you need help.

This was over a year ago when I was first getting into BTC, I no longer have that computer . I wish I had known about this forum then.

One of the biggest fails in a while...

Contact buyer and say you lost sensitive data on the hard drive which you'd like to attempt to recover. If the new owner is using the computer offer to buy a new HD and copy all the data over. Also offer him some money for the convenience.

I sent a total of 4.0624 BTC to the genesis block that was mined by Satoshi Nakamoto & which can't be spent due to a quirk in the way that the genesis block is expressed in the code (this may have been intentional).

1G5apmPvo2iTtmkNWAHTCET7Y842Ufijs8 ~ I sent 0.0624 BTC on 2012 07 15

1ASTRv7aBipHxXH2iF5XfchNBdWWYbjbSo ~ I sent 4 BTC on 2013 01 27

http://blockexplorer.com/address/1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

The total all together that's been sent there (including the 50 BTC mined coins reward) & hence it's balance is 63.02319969 BTC atm (last TX was for 1 BTC on 2013 05 26)

I'll let someone who's been following this thread work out what's best to add to the running total, I didn't see the genesis block mentioned before here but expect that I may have missed it in my quick look through the posts.

Why did you do that? Throwing a penny in a wishing well is cheaper

Yes, indeed: https://bitcointalk.org/index.php?topic=157401.msg1674850#msg1674850 - I like to think of it as the ultimate Bitcoin wishing well, rather than the balls up that I made after too many drinks.

The first 0.0624 was for fun or something, a symbolic recognition of Satoshi's work, but the second 4 BTC was doing a TX when tipsy & the blockchain.info wallet had remembered that as a previous address I'd sent to & helpfully suggested it when I made a typo or mis-clicked or something, really scary as it could have been much more but all totally my fault, I weeded out my address book after that.

Edit: Maybe I had it labeled as Satoshi's genesis address & it was in my brief time of playing with SatoshiDICE which I saved a few entry addresses for & confused it with one of those maybe, not sure - those brain cells like the coins are gone.

Haha, I guess you wished you hadn't done that, but it didn't come true huh?

Oh and sorry that made me laugh, I feel sorry you lost 4 BTC. Tough luck dude.

[Otoh]

Lol, hehe, that's OK I made a wish anyway, a different one

can't say if it's come true as yet because meant to keep those things secret

Only the genesis transaction itself is unspendable.  Any other transactions redeemable by the same key will work fine.

Ah interesting, I hadn't realized that, so if Satoshi has the private key to that address still, which I hope, then it's like a gift to him, better still!

Satoshi is standing behind his computer cheering. YES! Now I have 1,000,004 BTC ! W00t!
