LOL. I don't think that the Chinese would isolate themselves again. They have done it before but when they open the doors China exponential growth was realized. And if such scenario happened, then we can adjust to the situation. We might as well found another country with cheap and abundant supply of electricity taking over the mining from the Chinese. I think a lot of individual would love to put up mining in different continent because right now we are totally dependent of the Chinese mining industry. We will create alternatives to sustain bitcoin ecosystem.
