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?
That's not a good indicator to judge that because in overall one company doesn't own 50% of all coins and if china owns that much in overall, then we have to keep in mind that their population is far more than for example whole european population.
Btw it will be interesting to know what will happen in china around this task. They wanted to ban bitcoin. Now europe and usa wants to get factories back from china. China left without bitcoin and factory industries will be in very bad situation (bitcoin won't have huge affect but it's source of income).
