They are just closed minded and doesn't want to do anything with the current trend in technology. I think countries will soon unban it because of its applications. They shouldn't be scared on what they are doing with it. Hoping that soon, it could happen.
i think it is not yest banned in most of the countries. as most of the countries has not given any statement like this, although they have not consider it as legal currency but still i will like to add that they also not banned bitcoin and still people are using it as legal currency.
