I'm sorry, that was a brain-dead mistake. It has been awhile since I've bothered discussing the satoshi drama. But the point remains that he indeed was anonymous and clearly spent lots of time and attention to detail in everything he did, so to somehow conclude after knowing this that he was careless when it came to his bitcoins is an asinine assumption. It doesn't matter what the exact amount is, whatever satoshi controls exists and is significant unless you want to put your head in the sand. There are other players like mtgox and slush and pirate and knight that may have as many or more. It is as easy to imagine 10-15% of all the bitcoins to ever be mined being in the hands of half a dozen people as it is to imagine that a vast portion of early coins have been lost. Just because an argument can be made for the latter does not mean that the former is not a distinct and realistic possibility.
The argument will continuously boil down to "you can't prove it, pseudononymous lol", with terrible evidence from both sides. However...
I have strong evidence the same computer AND JUST ONE mined blocks 1-10
(edit: or a group of computers turned on exactly at the same time)
Just look at the extra nonce in the coinbase field of the coinbase transaction.
The counter is monotonically incrementing at a constant pace.
Also this can be used to find how many computers/threads where mining at some time (until they get powered-off). Each thread has another monotonically incrementing ExtraNonce variable.
So from that we can infer Satoshi PC Resources. Those resources allowed him to mine a block with 32 leading zeros every 6 minutes.
While Sergio has had a couple bad arguments in this thread, if this is true--I can't verify it because blockchain.info does not display the extra nonce and I don't see a raw copy link anymore--this would certainly have strong implications that satoshi indeed had the resources to mine 50BTC/~13min throughout the difficulty 1 period. 70 minutes passed between blocks 1-10. lol @ 14kh/s between blocks 0 and 1, that's obviously satoshi trying his hardest to mine for a week rather than him waiting for public release before mining.
