why does it matter?  whether it was 20, 200 or 2000 coins lost, it's a small percentage.  I don't see the point of making a list. 

it is presumed that the first couple hundred blocks from genesis were done with throw away wallets, they kept changing addresses and playing around with the code and thus the amounts satoshi has physical access to is far far far less than people expect.

while its hard to calculate how many addresses he discarded as part of his testing, it also becomes hard to get a definite amount of lost bitcoins as many would not want to admit their stupidity of bad back up processes or ignorance that bitcoin would ever kick off from the early days.

so whole alot of people are shouting out small numbers.. the reality could be much larger

Less bitcoin = less supply, less supply = higher price.

This is never going to be remotely accurate. I am sure there will be reports from scam artists, trolls , or just people wanting to avoid taxes claiming "lost" bitcoins.

It would be impossible to get a good figure. but, rest assured, there are thousands of lost coins. Like someone already said that at the beginning they just "messed" around with it to get the code, plus at the beginning, bitcoins werent worth anything, so there wasn't a real need to save any. I think most people really started to save them when they had a value, i believe it was around 60 cents on mt.gox, Im just guessing. I've heard many stories of early miners "forgetting" about the coins and have no idea where they are and others that have spent days looking for them. Some with success. But, I bet more coins have been stolen than those that were just lost at the beginning. The first theft that I heard of was around in the summer of 2011, the guy had 500k worth of coins stolen and thats when btc was just at a few dollars, I believe he committed suicide.

But, it would be interesting to know the "Exact" amount that are missing. I think when we see a massive dump is possibly due to a thief dumping his coins. Mt. gox has a few hundred k gone, the numbers could actually be quite big...(which is actually good, less coins should raise the value I think) But, we better get more secure or the threat of loss because of theft will deter many people from adopting.

Does the coins was really lost ??
 i lost my a little on C-CEX  because of my careless,Click  the' dump' button,but i don't think that it really lost.

i think there's nothing we can do for those bitcoins lost so what the list is for?

To know if it was a small percentage, I guess you'd need to know how many were lost. For all we know, it's 5%.

The list is just for informational purposes and over time, to see if it does cause significant deflationary pressure although I suspect we won't be around to see that time.

It would be interesting if someone had the addresses for the initial blocks but these are probably indistinguishable from Shatoshi's accessible loot.

I can see that people won't want to admit to mistakes but I hope this could still be a useful resource for the community at the end of the day.
