I can't find any info about closing binance, plus they have tons of international clients which makes it difficult for China to completely close them. Maybe they'll just won't allow chinese people to use it
True, but Binance is international. China can't ban it, it can only prohibit its citizens from using it.
I don't think Binance is international, they're completely Chinese, aren't they?
Thus, a mojar ban will hurt it very much including its investors and traders. It can turn into a dead lock.
