To my opinion there is no fear of banning Bitcoin because most governments, at least in developed countries, are aware that Bitcoin and cryptocurrencies can't be marginalized anymore.
And well aware of its potential value in the future,. perhaps only those countries that is under military dictatorship can be against it or at least don't want technology innovation.
Thus, this ban will be a long process for every country and sure the voice of the people will be above of government before it will be implemented. For now I even don't see any threat for the government to ban bitcoin especially in my country and besides there more big issues needed to be focus than bitcoin.
