Now a days it,bitcoin is ligal in india.Pm also agreed with this. He is not against with bitcoin. So now it is not iligal. It is legal so we can carry it.
The government has started to take bitcoin matter as a serious situation now.They have not made any stance whether to make it legal or not but looking to grab individuals with higher trading transactions in fiat for btc.They may even close the exchanges if they feel a lot of money is used for illegal activities
In India, i think the bitcoin trading is legal because many people do bitcoin trading in India and many trading sites are opened. maybe the bitcoin will become legal in India.
