Hi there CryptoBry, I think it is impossible that china will totaly ban all transaction, companies and other activities in relation to bitcoin or the whole cryptocurrencies. There could be several reasons behind, I just state two for you.
First, bitmain which is your famous developer of mining rigs are based on china and china want to be the leader of everything and they will not let bitmain tranfer to other countries.
Second, since bitmain almost reaches a revenue just lke nvidia it absolutely pay a huge amount of taxes which benefited  the government.
