What will happen when the center of world finance moves rapidly from London, New York, and Hong Kong to Silicon Valley?
I don't think the center of world finance will move. I think there will be no longer a center of world finance, because with Bitcoin centralized entities are no longer needed. Corporations and users can operate borderless anywhere they want.
There's nothing to fear about the changes Bitcoin will bring, because all these changes are positive and will empower the average citizen.
Wouldn't that be scary if bitcoin brought the Russians into power
It won't happen because of Bitcoin. It will happen (Russia+China), because the world is fed up with being slaves to the constantly warmongering American hegemony and all the power of the US relies on the dominance of their currency, which is slowly eroding. Imho, Russia as a new world power can't be worse than the US.
