Yes, this is really confusing, why is China is issuing more strict laws towards Bitcoin and cryptocurrencies at a time when countries are starting to open up and take strategic reserves of Bitcoin?
The most likely reason is probably because they have an authoritarian government that refuses to let its citizens go outside its control, as we know Bitcoin is decentralized and out of control so this does not please China, although I would have thought that they would move towards opening up more to Bitcoin as the US did, at least in the context of economic competition with the US.
