maybe the government doesn't understand bitcoin, as in my country it's still not permitted / banned on bicoin, but many have played bitcoin in my country, except in some parts the government doesn't know what bitcoin is, and I'm sure sooner or later they will know what it's bitcoin. and immediately permitted
If you will ask me why does the government hate bitcoin, as stated above maybe they do not understand bitcoin yes that is one of the reason and I think it is also because of some illegal activities using bitcoin and other cryptocurrency. As of now, I think Bitcoin is in discussion in every government meetings. Some countries who banned bitcoin is just want to avoid illegal activities that has a connection to it and to avoid their citizen to used it.
Hopefully in the future, many countries will believe and understand bitcoin as we do because even though it is decentralized still it can really help us to improved the economy of one country by using it properly.
