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!
Perhaps, one the main reason why china is not in favor of bitcoin is because of their economic system. The government of china hates individual operations, almost all their market industry is run by the state. So how would they ever allow a decentralized monetarial system. There are also speculations that China will create their own cryptocurrency.
