China taking down blockchain related mining is out of the attention of the cryptocurrency market because the Chinese government is not stupid, if they want to take it down they would have done it long ago when they ban Bitcoin and the reason why they ban Bitcoin is because they believe it a threat to their CBDC and power since they are marxism country.
With that been said, if China bans crypto mining today it won't affect cryptocurrency but it will pave way for solo mining.
everything aim for regulation and the interest of the government. Chinese leaders are learning about blockchain as well as cryptocurrencies to find a way out, they're no stipid.
I think in the end, China will accept bitcoin together with mining, but they'll develop a pertinent law on all those stuff.
