http://blockchain.info/fb/12hiI believe this address would be high on the list if it wasn't "cleared out". I believe this one belongs to Satoshi because the oldest transaction was 3 days into bitcoin's existence. It seems a lot of mining rewards from the very early days were sent here. I tried to follow the money, but bitcoin did its job and led me nowhere.
Znort, how about running the closure and 'taint' tools on this address, that would at-least give a broad-brush generalization of if these coins were scattered to the wind or stayed consolidated, I suspect it would be the former as people were much loser with BTC back then when it was really worth nothing.
Very interesting address, and very interesting closure.
The closure is fairly large (around 393 addresses).
The earliest TX into the closure is a block mined on 2009-01-13.
(Interestingly, that is earlier than the first TX into the address given:
one of the nice property of the closure tool is that you can sort of travel
back in time.)
After that there are a whole bunch of
BTC50 TX paying into the
closure (likely mining revenue, didn't bother to check that they
were actual block mined type tx). The owner is definitely a very
early miner.
The balance for the closure peaks at
BTC95k around mid-2011.
Either the owner decided to cash out at that time, or he decided to
spread his coins to addresses outside of the closure to be less "visible"
Transactions in or out of the closure are nicely spread over the range [2009-today].
Latest TX in or out of the closure is from 2013-04-04 which seems to
indicate that our miner is still alive and well

To get a vague idea of where the money went, I ran a taint analysis of TX
paying out of the closure.
Because of how early this closure starts, it almost taints *every* TX in the
chain, so I chose to only keep TX whose output is tainted by more than 75%
by the closure.
That's about 2028 transactions, involving about 5000 addresses. I computed
the balance for all of these, and ... the outcome is very interesting
