65% of Global Bitcoin Hashrate Concentrated in China. Half of the country’s hash rate is produced in just one place, the autonomous Xinjiang region, which makes up 35.76% of the global total. Can bitcoin be banned there and, if so, will it effect the crypto market?
If they ban mining in China then the rest (%35) will be securing the network instead... The network will keep working. It won't get affected by it. I don't see big deal. Actually that would even be a good thing which'll remove the Chinese centralization which you pointed out.
