How can mining be decentralised it is associated with price of mining and electricity, and if you can get cheap electricity, you will get more BTCs this can be changed in future. And most of btc will hold investors who are willing to buy them no matter where they live in China or Europe.
If Satoshi wakes up i doubt he will kill his child.
So basically everyone in the US that points there miners to a Chinese pool is basically screwing themselves and the whole BTC community outside of China.
