People will still find ways to circumvent this ban. In many countries weapons and drugs are prohibited, but they are used. The same will be with bitcoin.
But for bitcoin users it will not be hard to regulate their bitcoins and to transact their money to any other place in the form of bitcoin as bitcoin is unable to detect the ban will fail as it already happened in the future with some countries.
to me although people will still using bitcoin. but still i think government willl create problem an no one can challenge the decision fo the government and must accept the government decision.
