Anyway crypto currency will be going to regulate in India very soon because of already top list country are regulated the crypto like Japan and more, and coming days some big companies like Facebook and telegram launching their own crypto coin, so I hope that Indian government and RBI will getting the crypto regulations in India very soon.
I think they will change their stance towards crypto, now that libra (fb) and ton (telegram) are introduced and many other popular institutions are following thru also. For sure, they have big number of FB and telegram users from their country. And if they see that big companies are supporting crypto where most of their constituents are already part of, I believe they will loosen up a bit and will put regulations instead of totally banning the usage of it.
