The government wants to control bitcoin and soon if several more countries ban it, the price may drop significantly. Bitcoin has grown very well and is a huge competition for the banking system.
I don't know why people say this things like government will control bitcoin etc. You think bitcoin will be decentralized and stay decentralized all this years if the government know this will happen? And now that they know that, why aren't they having any movement about it? It is a huge threat to the banks but government don't really cared about it. They are happy collecting taxes so they are all good.
