I think its criminal for government to ban this. To take away the jobs in BitCoin exchanges without any sound reason. Its abuse of power. And the BitCoin community will fight back if it happens.
Its definitely not criminal .. Its scare of a new technology ..
Mahatma Gandhi broke salt laws. Was that criminal ?
If you break a law it is criminal activity and what Gandhi did was civil disobedience and if found by the law that you are doing it you will face the consequence, apart from that Japan legalized bitcoin recently and hope the government in India will learn about bitcoin rather than taking a decision without any major thought.
