It can be good work but I am scared if it becomes a general solution they try to find the ways to ban it.
They can't. They can't ban the internet of the whole world, and bitcoin and all the altcoins.
But they can limit the websites that trade bitcoin, the servers..., use proxy and close the ways of limit although it seems impossible to do this 100%
They can't make laws in foreign countries.
They can do some limitations. But not great. And if bitcoin is limited, next day an altcoin will take its place. Here and there somebody will accept their "money". If nobody else, then China or Russia will do.
