Its not that the governments is against bitcoin, it is actually the government being problematic about the taxes, since bitcoin has no relation or is neutral to a country the government does not cover any of it, which means the government wont have any benefits from it, and this is the reason or one of the reasons why governments and bitcoin does not cope up with each other, take note not all governments has illegalized bitcoin, as a matter of fact a lot of countries have gain trust with bitcoin and has legalized them for the good of the country.
