Just because a large amount of mining is done in one physical location doesn't mean it's not decentralized. All mining is done on earth. Does that mean it's centralized? I think the implication is that the Chinese government has influence over the currency. If that's true (and I don't think it is, or that they even have any interest, given the rise of crypto capitalism in HK and mainland China) then they could at most attack the network once, completely destroying its value. Sounds like a lot of wasted energy when people can 1) fork BTC to circumvent this 51% attack, and/or 2) opt for another currency to replace BTC as "digital gold".
