No it's not banned in India, though there is no clear stand on this by Indian government. As far as I know you can still trade on indian exchanges and deposit/withdraw funds through those exchanges. Zebpay, Koinex, BitBnS are some of the good exchanges. Yes there's some restrictions applied to them by banks and there is court case filed by crypto space people against the reserve bank of India. But it will take some time till this situation got clear in India.
