As far as I know, China has not completely banned the cryptocurrency, but is in control.
At this time most people are panicking and selling their bitcoins, but I don't think that's a good idea.
I dont think many people are panic selling. I think a lot are actually moving their crypto assets into more secure coins like deeponion and monero. This way china can ban all they want, but with Tor and Meek, there is no really way of stopping a rocket like deeponion.
