afaik 90+% (100%?) of all the blocks mined by satoshi have never been touched. Satoshi's wealth would be in thousands of separate 50BTC wallets, not 1 big one.
Can't be bothered to find the source atm but someone did some analysis on the mined blocks in 2009/2010 and found the likely blocks mined by the same person who mined the first block, all unspent.
Either he didn't want to reveal its identity, because he (they) knew well that the history will remain for a long time, or he simply lost access to those bitcoins.
Thousands of separate addresses, most of those coins still sit in their mined blocks. However it is likely Satoshi has all the addresses in one single wallet so that he could move them all at once if he wanted to. Satoshi's estimated wealth is between 500,000 and 1,000,000 coins.
Did Bitcoin 0.1 have a mine-every-block-to-a-new-address feature? It's also possible that he mined to ephemeral addresses and didn't save the private keys which would make all that BTC lost.
Yeah, right now Satoshi is worth at least 100k btc up to 1,000k btc. Some analyses has found that perhaps 2,500k btc are controlled by the same group but that was highly speculative.
I would think Satoshi is getting close to becoming the first Bitcoin billionaire.
