The Ban on BTC in India would only mean that you can’t directly Exchange Crypto with the Indian Fiat...Tho you could do so successfully via International Market. As far as P2P function is concerned, well I think it would not see any restrictions if the Govt only bans direct INR to Crypto Exchange, But then again it would be absurd to merely keep your Crypto in a Wallet where you can’t Exchange it into Fiat. However, Govt can render complete closure of these Indian Ex anytime.
