Can someone be punished or sent to jail just by holding bitcoin in banned country?
What will happen in case of trading bitcoin in country where bitcoin is banned?
Ban is something like complete inhibition of use of something and I think bitcoin could never be banned. Bitcoin is very volatile, versatile and sustainable crypto currency and most important it is decentralised crypto currency and no country can ban it , only country can inhibit the use of bitcoin or any other crypto currency in their nation only, there is no offence in holding bitcoin and yes the person will not send to jail if he owns bitcoin, he can use international exchange with ease.
