Let's add up the KNOWN lost bitcoins

[JWU42]

i personally would keep 1000 satoshi in a couple of different wallets

Just FYI...

A Satoshi is the smallest fraction of a Bitcoin that can currently be sent: 0.00000001 BTC, that is, a hundredth of a millionth BTC. In the future, however, the protocol may be updated to allow further subdivisions, should they be needed.

i was being (trying to be) sarcastic, it turns out that it is hard to be sarcastic in text form

Claiming to have lost 15,000? Bitcoin? or do you mean USD. Losing USD isnt much of a big deal but losing 15k of bitcoin that would be incredible for everyone else invested in bitcoin except you of course that could possibly triple everyones money

FYI, I have 5 bitcoins which I lost the pasword for the private keys for, Im no whale, even though its allmost a year ago, it still hurts

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.

phi bitcoins were burned in this transaction recently

Somebody has just lost 40 BTC by sending them to the practically unspendable address 1111111111111111111114oLvT2:

How can they receive the lost coin again?

I see: "Unable to decode output address ".

It would be good to have the mystery behind those Satoshi coins resolved to help adoption. If he ever moves them the price will crash, and most bitcoiners know it. However, afterwards the fear of him dumping would be gone, which could reassure new people enough to adopt Bitcoin. If Satoshi did something good with his coins it could bring good publicity to Bitcoin to counter bad publicity like the Silk Road.

I have never been in this situation, but I would write a program that tests various passwords 24/7.
(I think any closed-source tool you download from the internet will just send the key to whoever write the tool when found :-)
Breaking the wallet private key is impossible, but a not too long password may be possible if you remember some parts of it, or at least how/if capitals and numbers where used.

May have lost 0.05 BTC sent by the faucet...

OMG, this is such an awesome thread for this post alone.  Can you imagine getting a payout like that from a faucet these days?  How much could you claim a day back in 2011 or whenever it was that faucets started?  I was not into btc yet back then.

I was into bitcoins already back then but didn't dug deeper. 2012, there were faucets who were giving up 1-10 btc per claim. Lowest I think is 0.001 per person (?) I'm not so sure anymore. It was fun, yes, but my mistake is that I didn't take notes of my previous wallet credentials and details (which I lost a total of 0.5 btc as far as my memory can remember.)

Do you mean you lost the 40 BTC to 1111111111111111111114oLvT2? Why did you do that?

Are you still holding the key to 1KdDvp1DJ4EYUZc8savutRN4vv1ZwvGfQf?

[Druze]

if you can you should update the amount at the top of the thread

+0.015 BTC , I sent that account to an address that is no longer active a month or so before by mistake, write that down 

[mkc]

+0.008
I installed block chain in my phone, and sent that much to my phone, and I lost my phone.

[jayhawk1]

+0.01 BTC, Sent the money to an unactive address that had it's private address lost previously.

[arklan]

+0.008

this one may not count, technically. i mean, its a safe bet that it's gone, but in the most precise sense, the phone is not with you, but the phone, with the private key, is with someone. thus, not lost.
