China is really dysfunctional with a tremendous amount of corruption and insider dealings. I think that's why some of it 'came back.'

If it were really 'banned' then it would have been shut down immediately - the CCP is a complete, total surveillance state.

I still stand by that the Chinese government views mining as part of a diverse cyber-security strategy... if Chinese miners can control the next blocks and therefore transactions, then they have 'an edge' over the United States and American companies. Even if they don't think this has a lot of utility now... it may in the coming years and decades. The Chinese think 50-100 years ahead, not 4-8 year election cycles like Americans.
