The government is still checking the use of bitcoin, it is difficult to track bitcoin users because it is anonymous.
So the government must have a special team for this case, but this is not easy.
Yes, i am totally agree with you in this matter. The goverments want to use the bitcoin and the cryptocurreny because they know that they will be good and profitable for them. But there are some little nuances between market and goverments. If something is anonymous the goverments can't like that, they always want to track everything. So thats why they afraid. But they can't hold on like this, they will accept it soon or later.
