No, that's not gonna be happen. We all know that government was categorize in centralization system while Bitcoin was categorize in decentralization were obviously the government can't able to control bitcoin because of this wonderful and great features of bitcoin.
i agree its hard to be stopped. but if all country declare bitcoin illegal, i wonder what will happen to the market value. what makes goverment cant stop the coin is because the technology that cryptocurrency had such as blochchain . k still believe the future of all of thing related to business is this technology.
I think the government will not stop bitcoin, now bitcoin is slowly get involve in society. Just look at the government of the country of Japan they made bitcoin legalize and they are the proof that bitcoin will never become a threat for a country and bitcoin will become a huge help for them and that is why not all the government will banned bitcoin.
