I read somewhere yesterday that China is welcoming all crypto exchanges to its country for a peace operation, US don't know what they are throwing out of the window right now, crypto isn't the reason why the USD is losing face, they are trying to make it look like that, but I suspect that many US citizens are moving their money off bank accounts into crypto investment and the government doesn't like this.
It's better if Binance leave the US for good, but I think it was not easy for CZ to run the Binance US in the first place, and he believes that the US citizens are playing a major part in the adoption of crypto, that's why he didn't want the US out of the book, this is my own thoughts, nothing confidential.
