That's the question came up into my mind actually, as far as I know Russia is one of the country that I can say their promoting the advantage of bitcoin. Because adopt the system as well in their country and also they have big Bitcoin community over there.
i think just do some back reads on this thread and you can see the link of the reason why Russia banned bitcoin. you can also see there the list of the other countries which do not accept bitcoin. just search on this thread bro.
Maybe it has something to do with the weak ruble.
The russian government does not want to give their people another possibility to get rid of their own fiat.
