One wallet with 980.000 BTC might just be a time bomb.
There is no BTC wallet with 980K coins. The richest wallet contains 144,341 BTCs and is tagged as DPR Seized Coins.
In my opinion, Satoshi is not possessing a large number of coins. He created the BTC for ideological reasons. Stashing up a large number of coins will be against his morals.
DO NOT POST SESC LINKS I find it hard to believe that Satoshi would not obtain at least a few examples of his own work, at least in celebration of his accomplishments and the potential for them to take off. A man has to take pride in his work. I'm not necessarily implying he has tons of bitcoins but I'd be surprised if he didn't have at least a few.
