Didn't China also crack down on mining as well as banning China-based exchanges? I can't remember if I read that or not, as I don't follow mining news too closely. All of this sucks for the Chinese, because crypto is huge for them and my guess is that they see it as a big middle finger aimed squarely at the Chinese government's face. After all, crypto can be regulated, exchanges can be shut down and mining operations dismantled by law, but there's nothing the government can do to eliminate bitcoin and the rest of the cryptocurrencies.
I'm hoping this doesn't become a worldwide trend. China may have its own thing going on (always has), but you can bet other countries are following what's going on as far as crypto goes.
