It's not a secret Satoshi Nakamoto has more than 1 million of Bitcoins in his wallet, right?
If he suddenly wants to sell all his Bitcoins, could it cause a chaos in Bitcoin market making the price fall? Or is this amount too insignificant to cause any mess?
Even if he wants to sell all his bitcoins he have to go to exchange for selling and when this much high transaction will happen the exchange will stop that acct withdraw and all problems will start so i think he wont do this mistake and sell slowly slowly so that the coins will also get sold and it wont affect the market.
