Wow,this is a surprise to me...
I have always thought that satoshi may have deleted some of his wallet, because he may think that having so many bitcoins may be dangerous for the own bitcoin
Its impossible that Satoshi just deleted his privkeys: if he wanted to delete this bitcoin forever he could burn it via OP_RETURN. Satoshi surely know about this possibility.
it is the other way around: if he would use an old address with millions of coins, BTC would take a massive hit. i guess all early mined coins are lost. he did not sell at 1200 USD, so he will never sell/move those coins and that is good for the whole system!
He thought that btc reach 10m$ price. And he cant sell any significant amount at 1.2k$ anyway. So i think he is holding. Why do you think he is greedy? Probably he is high-quality specialist with big salary and he has enough money to live as he want. He could take pleasure from his btc, i mean that nobody, his neighbourhood, kin, friends dont know that he has billions in the pocket its funny from one point of view.
and has deleeted the early wallets because he wants good for the whole bitcoin project. he would hurt his own
baby alot if he would use the old coins.
