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?
Yes .Bitcoin market will be fallen.1 million bitcoin is huge amount of bitcoin. If he sell all of his coin in one time, the effect will be decrease the rate of bitcoin.
