Well I agree with you, mate.
This does not only apply to China but with the rest of the world because all governments across nations desire one thing: CONTROL. In the world of Bitcoins, there is not an inch of control. In fact, only those who have Bitcoins are the ones who have ABSOLUTE CONTROL over their Bitcoins. They can do whatever with their Bitcoins without fear of being held by law. They are free to manage their own affairs in the world of Bitcoins, hence, Bitcoins' continuous growth! That is why it has been said that Bitcoins can be a very effective way to achieve illegal affairs through online Bitcoin transactions because of its value for anonymity across borders, around the globe!
An absolute control for government on bitcoin would be a disaster for bitcoin itself since corruption is an easy thing to happen after that just like how they control fiat money and the prices of each goods. I really do hope it never happen or else some people would be leaving bitcoin but government would still not care about it since they're in control of it and will easily control it's price.
