China also mined a lot of Bitcoin when mining was cheap, and it is certain that it has serious BTC in its hands. But at this time, China has banned because it needs serious energy. He banned mining when there was a loss in energy.It seems that China does not have such a strong ban on cryptocurrency mining if this country is still ranked second in bitcoin mining. Or the authorities are not able to control the implementation of their own ban. It is possible that this also suits officials. In any case, it seems that the fight in China is not with cryptocurrency, but with the uncontrolled use of energy.
