I don't think that in my country government will start accepting bitcoins or will start supporting bitcoins as they are involved in corrupted activities and if they start accepting bitcoins then it will be an full stop to their insane activities so I don't think that it will ever happen in future.
Not all the governments are same there would be many who will believe in development of the country and allowing bitcoins will help them in reducing the unemployment issue and will contribute in better development of their economy.
yes all the governments are not same i think some of them in future will allow the bitcoin if all the people know about it and also bitcoin is very helpful in reducing the unemployment.
