I think the government can not mix Bitcoin transactions. Because, Bitcoin moves at its own pace. Bitcoin transactions do not know anyone else. Even the person who does not know what he or she is dealing with is about the matter. However, the government can do it that Bitcoin can give permission. As many countries oppose Bitcoin. All those countries will be able to use Bitcoin freely if Bitcoin allows them. That is why Bitcoin market will be better again. Which is the hope of all the Bitcoin Premiers.
