Bitcoin is good and some govrements means that bitcoin is not good for their economy.That countries are ussualy poor countries with weird politician leaders so they refuse bitcoin but there are 2 normal country Sweden an Norway and they are making own cryptocurrency.
That is quite a bold statement don't you think? The government usually Ban bitcoin because it is not issued by them
and the most common reason are it can be used for illegal activities, bitcoin don't have any rules about how to
use it that is why the government is banning bitcoin to prevent illegal activities involving bitcoin.
