What If Bitcoin is banned in your country will you still use it?
If you use it how will you? How will you exchange it and how will you completely use it as you do before.
Although bitcoin is prohibited in my country, I still can use it, just sell bitcoin to USD and use paypal to withdraw money, it is very simple.
It is impossible to ban bitcoins because bitcoins give the concept of more secured and efficient decentralized economic system which continuously challenges the local economic system of the states. The prices may fall/rise due to the ban on bitcoins but this will never discard bitcoin from the world.
