Satoshi might be having a hell lot of coins than what is known to the public and in the earlier days when the block reward was 50 bitcoin he was the only person mining until others joined and the main reason he did not move the coins from these public known wallets is simply because he mine other coins as well, if not he would have moved the coins when the price touched all time high valuation, then there is another puzzle whether he has the keys to those initial coins, either way the list looks cool .
