Ask yourself how many Chinese citizens use Bitcoin (not trade, use). Then ask yourself how many have been affected by concerns from the "ban" (as OP notes). It's worth reminding that most of these bans relate to commerce and trading, and no state has really ever gone after a citizen's normal use. Too expensive, too complicated, no returns.
Ask them about Internet Great Firewall first, they break it.
Then they break Bitcoin ban from Chinese government if they want and have need to use bitcoin.
Not many Chinese people especially the young are care about Chinese government ban on Bitcoin because they know ways to use bitcoin but surely must do that more carefully.
If you're a regular Joe, you never had anything to worry about.
Average Joe is one condition and another big condition is never use bitcoin crosses bank system. You can use bitcoin in many ways, just don't sell your bitcoin and receive money in banks. Firstly there is tax issue, secondly if somehow your trade partner has big trading volume and get legal issues with government, your bank account, history, and you will be under radar of government too.
