In my opinion there should be no government policies for Bitcoin because if the policies of government will apply at Bitcoin then the Bitcoin will become like fiat . It will have high transaction tax .
But there is no other way around it. Governments will impose such policies whether we like it or not. Most influential governments have already revealed their attitude toward Bitcoin, and truth to be said, it has been barely tolerant so far. We can only pray that they won't start preying on us if their attitude goes from bad to worse over time.
