That's yet another reason why they wouldn't. Even Russia and China have too much to lose. Even Iran's government would be looking at a net loss of power. The DPRK is about the only state actor with means, motive and opportunity.

Either way if satoshi was an independent actor or a US govt individual (not the Fed; very important distinction) the US has the most to lose. How do you create a bid for your paper bonds? Re capitalize the system with something of value.

I know who Satoshi is. The creator of Pokémon!
