Chinese citizens and the law
The short of it is (as I state in my writing) Chinese citizens are prohibited from buying/selling/having an account on an exchange, but are permitted still to “own” crypto:

Percentage of Hashes (mining/block creation metric)
Miners are raking it in from their operations and energy subsidies from CPC:

“Yet, the idea of geographical centralization is a concern, albeit one that has been exaggerated by those who want to paint bitcoin and ethereum in a certain light. It is factually correct to say that Chinese bitcoin mining pools control a large amount of the hash rate that powers bitcoin, for example. A study in 2019 estimated that there was about 65% of the hash rate within China itself. This was largely due to cheap hydroelectricity (especially in areas such as Sichuan), and close connections between hardware manufacturers based in China and mining pools/miners with the best claim to established relationships.”
