We all know that there are a lot of Chinese billionaires and I'm sure the bitcoin or at least crypto in general is on their radar to expand their wealth, so this is a win-win situation for the Chinese government, Binance and Chinese people themselves.
I'm pretty sure that if native billionaires in China end up taking a position in Bitcoin, they will do it through the unofficial channels. China has been extremely aggressive towards the wealthy elite when it comes to what assets they buy into, mainly for the purpose of preventing capital flight, which Bitcoin obviously is the perfect tool for.
China rather keeps limiting people's freedom and not gain anything financially than to allow decentralized protocols such as Bitcoin to gain ground.
