Though that the government has been looking for various ways to stop or ban Bitcoin and its mining activities ,but I don't think at this stage of awareness and adoption of Bitcoin, that this is gonna be that easy for them to completely ban mining. Why?, This is because it's not gonna be easy to have a global ban on Bitcoin mining happen at same time. reason, this country may find reason to ban Bitcoin mining while the other country may see reason to adopt or see an opportunity to continue mining. Taking for instance, China banned mining while US took the opportunity and Increase their mining firms.
This is my confidence, because countries of the world are in problems and some are fighting one another. The war in economy and every aspect of competition. Anything US reject, China will likely accept. Anything China accept, US may likely reject. If one US bans bitcoin mining, you will see another country will accept mining to make sure that they are against US. With this, Bitcoin will either be loved by one country or the other.
