So here is the theory.

Because RBI and Govt have given stern warning that those get involved are at their own risk, and that its highly risky, banks cannot go back to RBI, if any issues with these cryptos?

But it does not add up unless bank gives them loan which if these guys default later, then there is a substantial risk. What is risky in just acting as a payment gateway between customers and them? In fact, that helps keep things in account automatically. And its huge revenue for these banks acting as intermediary. Why would they choose not to, when many are in bad shapes due to bad NPAs.

By these arm twisting tactics, banks are only pushing people towards more and more decentralization proving bitcoin's point.

Btw, coindelta seems normal as per their website. coinsecure only kyc issues, which i hope has nothing to do with banks.
