That's not the fault of bitcoin, but the financial inefficiency of most of the countries banning it, or the fear of an unregulated currency in some countries -which do not believe in anything "free"-
Russia and for a brief time China, banned bitcoin for users due to the fear of increased devaluation of the currency if was traded directly to USD, something these countries are used to doing monopolizing the economy of their countries. Ecuador, mostly due to fear of the unregulated community and currency.
