However I don't think there will be further ban on cryptocurrency usage within India. As per the recent G20 summit the standards for anti-money laundering and counter terrorism funding will be set by Financial Action Tasks Force (FATF). Being a member of G20 India will also be following the standards, this in some form assure that there will be no big issue with ban on India anymore.
That's true, we're talking about very serious actions which could be taken by the government of India, but I don't think they will let down such huge community. India is doing great with their cryptocurrency development and growth of their exchanges, it's becoming more and more important part of global economy, and this country must be part of it. India is not the only country, where cryptomarket is going through some troubles, but I think they will handle it properly.
