It is the last step before the win( first they ignore, then they laugh, then they try to fight).
But I doubt, it is a new tech and highly manipulative one, China baning it might mean they behind in a technology that they could control.
Think they will desecourage the addoption, and win some millions with fake bans and manipulative stuff like that, until it is clear where the bitcoin will go and if they can control it, instead of ban it
Regulating Bitcoin would be a better thing than banning it, since banning it is almost impossible, and regulating it would encourage mass adoption.
By the way, some retards apparently thought that "Bitcoin banning China" is possible after reading the April's Fools Article on CoinDesk.
