I see the government as greedy. There are several ways to tax citizens. Direct and indirect tax exist in every country. Owners of cryptocurrency may not pay direct tax on their cryptocurrency, but cannot avoid paying indirect tax. Again, it is a small fraction of the population that are into cryptocurrency. So the agitations by government from my standpoint is unwarranted.
Governments are now realizing the need of Bitcoin and that is why recently we have seen the act of Germany and recognized the Bitcoin for the first time ever in their history. This need is feeling to other countries as well because they are watching and observing the economies of other countries which are using Bitcoin. They also need this and soon the whole world will demand for it.
