Ok, let's assume that the following scenario is actually possible, I would like to know how you feel when all these thing happen at the same time:
Bitcoin is under a 66% attack (double spends are happening)
Is also banned by the US, Russian, EU and China government by threat of 30 years jail time.
The real satoshi (proven by something) is found dead, killed.
Uh, you mean 51% attack?
