I think we always need to keep in mind what kind of system is in power there, relationship towards cryptocurrency such as BTC can hardly be changed while communism is in power.
I strongly agree with this. Banning YouTube and Facebook is a not forward-looking move which prevents Chinese people from learning and communicating with other cultures. This looks more like what North Korea would do (which they certainly did) and it's a pity that China, or Chinese government, to be more precise, is similar to them in this regard. I doubt that they will manage to ban all crypto platforms except for the Chinese ones but even the intention to do so is hideous. Luckily for them, Chinese are not so brainwashed as North Koreans and I'm sure they will overthrow this communist government sooner than one might think.
