Since Satoshi owns 980,000 Bitcoins, what would happen if he suddenly sells his Bitcoins?
At the actual rate hic coins value is more than 6 billion dollar.
Two likely case will happen:
One, bitcoin will go to 0. It will be epic fall as people will panic and dump hard. Much worst than Mt. Gox or Silk Road combined.
Two: Miners will continue to mine, investors will see this as a perfect opportunity to scoop more because there's still millions of bitcoin waiting to be mine and their is still profits to be made.
