At the moment, I don't think a ban on crypts or bitcoin is going to be total (if at all it will come ) , this is because bitcoin is decentralized and distinct countries have started looking for accepting it because it would assist there economy when they invest on it.
That is what Japan has done. They recognized bitcoin but they put some rules and regulations on it. They also are investing in it. Honestly, smart countries would do the same if you ask me. Why ban bitcoin if you can get benefits out of it since its use is large? I do not really agree with what China has done.
Plus, even if they ban bitcoin, they will continue to use it on the dark net and will also continue to do their illegal activities. On the other hand, if you do it in front of the government's eyes, it really will be okay! (I am not talking about the illegal activities).
