I believe China doesn't hate bitcoin. China might hate the fact that it's untraceable, and with the problems that rised with the ICO's where many investors were scammed, and lost money, they couldn't do anything to retrieve that. It's a risky market, some will opt out of it, some will just act that they will opt out, and others will continue following bitcoin!
Because if China cannot control something, it bans it. Of course, one doesn't have to be a communist country to take that tack. Many other countries see Bitcoin, and other cryptocurrencies as a direct threat to their financial dominance of the markets.
