I'm unsure whether it was menitioned before:
Every coin the thefts have withdrawn from Mt.Gox was somehow doubled in the past. It was most probably sold by the thefts _and_ it was blananced at the Gox user accounts.
So now there are a lot of people that have less bitcoins than they thought they would have a week ago.
you mean 7% of the coins "gone" = 7% price rise ?
What idiot that is capable of stealing 750k of coins is going to risk it even entering an exchange? How many hacks have we seen of X amount of coins enter the free market? None? We will probably never see those coins again since it going to be sold in large chunks to heavy hitters.
