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.
bitcoin will always be good for their economy. maybe bitcoin is not yet officially discussed to their government thats why they dont have good thought about it. maybe if it is officially discussed to them they will know the good factors that bitcoin can bring.
Indeed, Bitcoin can bring a number of benefits to the economy, due to the decentralized way it works and due to the fact that it is a deflationary currency, which brings certain benefits in relation to inflationary currencies. But while it is something that can help such countries, governments probably would not support it because that is something that would diminish the power they have in those countries.
i think bitcoin has already great impact on the economy of the countries, and specially those backward countries who have access to bitcoin. because in backward countries the unemployment ration is too high and if they get access to bitcoin they can get money even by invest a little amount of their assets specially in alt coin, and those who have good skills of designing or can provide other good service so they can get job in service section in bitcointalk.org..
