China banned BTC many times already yet still this has an impact on the markets. Maybe just because people want to get prices lower from time to time..
Anyways for now there is no official info from chinese government on this.
Actually all that is there is the exchanges will have to register - like in many other countires. Currently they runned as wild west and thats it.
NIFA (China’s National Internet Finance Association ) wrote that many exchanges hosting ICOs got many warnings and its time to legalize everything and put rules on that.
Also if exchanges in China would really get banned - that would mean OTC sales would be bigger and BTCs price could raise - since it would be harder to get BTCs.
