it's true that China is a country that wants to dominate the economy of the whole world, we know the biggest mining is in China, but the government bans cryptocurrency, I think this is just a strategy because they don't want to be controlled by other parties, it is likely to make their own crypto
Basically it is totally different to consider only mining and not the entire domination of bitcoin to their country. Cryptocurrency is powerful and they know that, and thinking about the fact that mining is a good business where government and their economy could also benefit, it doesn't necessarily mean they need to adopt cryptocurrency. China is taking step little by little, and they know what to do and how to control their people for good governance because their population needs to be taken care of seriously.
