Most Bitcoin companies in China are as committed and decent as any bitcoiner (cue lambie), but I'm not comfortable with having to trust a socialist dictatorship to not interfere. They don't have to nationalize anything. That's what you do in a country when you are used to having to justify your actions. The chinese government will only have to make a few phone calls. I don't see why they would do such a thing, but again, I don't like having to trust them.
