Does bitcoin has a promising future considering most governments resisting to acknowledge and accept its use in their economies?
There is no problem about it. Have you tracked the pattern? There is already an opening up of countries to Bitcoin. It used to be so hard for Bitcoin to gain the green light of countries. But we have now seen several countries that accepted Bitcoin. Some are even removing the tax burden of Bitcoin. This is the start. I know this will still get better as the countries accepting Bitcoin are increasing in numbers. There will be a domino effect.
