What's really amazing is that they don't understand that they are cutting themselves out from a super-growing market, letting all major investor taking all their money to other countries (like the mining exodus happened recently).
Should we really expect a bear market?
China doesn't lose much if the miners shift their operations to neighboring countries such as Kazakhstan. Because the tax revenue from this sector is really low and the high energy consumption from the mining farms has resulted in power shortages in some of the provinces. In the future the Bitcoin prices may go up by 10x or 20x, and at that point the regime may regret about the crackdown. But until then, they are not going to care. The CCP still believe that their CBDC (e-CNY) will be able to replace Bitcoin, at least within mainland China.
