As I always say, China is a peculiar and different country, there's no chance we can predict the effects because of these strange things China already did
There is zero affect for bitcoin other than the mining difficulty will be reduced if they ban mining and there are other miners situated world wide and the Chinese miners will move out to safe pastures, so literally there will be no affect on the market.
China always say things, they will ban BTC, they will allow BTC, they will ban miners, they will not ban miners, so to me it's not wise to trust and predict any China speculation of government
I remember when the market used to panic when some stupid FUD comes out from China but the market moved on from that stage and no one cares about those FUD anymore, if they ban everything so be it and bitcoin does not revolve around any particular country.
