1. Satoshi mined almost alone from 1/3/2009 to 1/25/2010 (block 0 to block 36288).
He did not. I mined during that time so did many other people I've talked to. As you're probably aware the original software mined _very_ slowly, and contemporary hardware was slow. Heck even a fairly current machine with state of the art software can just barely do enough hashrate for difficulty 1. (and god, before more handout requests come: Bitcoin was worthless then, the software was annoying windows-gui only I ran it in wine+vncserver, and I didn't keep my original wallet)
Can we safely assume Satoshi mined blocks 1 and 2 ?
Both blocks have 32 leading zeros, very similar to the following 32K blocks!!!
So I can tell you with confidence that you mined very few blocks (e.g. 10 blocks) during that time and you're not millonaire, or you are part of the Satoshi group, period.
I have some evidence, from a comment in Bitcoin 0.1 source code, that Satoshi miner took "a few seconds" to do 2^18 hashes. That "fact" contradicts the hypothesis that Satoshi PC mined block 1.
That can ONLY MEAN that Satoshi (the person or the group) had 16 computers
OR the comment in the source code is too old to be taken seriously...
