The interesting thing about the Chinese bombshell is the rumour that China is not opposed to Bitcoin/Crypto markets per se, they just have a problem with them not being regulated. Logically, this opens the possibility that after the current round of shutdowns, new exchanges that play by the rules will emerge (or the old ones will satisfy whatever regulatory requirements there are and re-open). So this makes a tantalising long shot play - because if this is how badly the market reacts to China closing down the exchanges, can you imagine how it will skyrocket when the first "legal" government approved Chinese exchanges start opening again. The only issue is timelines and the nature of those regulations - will they take years or weeks to establish "legitimate" exchanges, and will the regulations be practical, and will it happen at all?
