I guess this have been happening all over the world. I remember reading recent news regarding coinbase and one of it's major banking partners. I doubt they will keep this for long, and are probably just trying to hit more pressure over bitcoin regulation. With moves like this, regulating crypto becomes a priority for all, otherwise the markets will slow down a lot since it would be hard to get more capital into these markets.
I wont say that this doesn't worry me though. If we examine things carefully, we can't really use crypto, and we need to buy it with fiat and exchange it to fiat in order to get value out of it. If banks shut down exchanges accounts, and payment systems that use crypto, like neteller or others like it, it would be hard to buy or sell crypto. I guess we would only be able to do it in person, and that wouldn't be very easy to do.
Of course I don't think they can do this by themselves and for no reason, so if governments allow crypto, then banks can't really shut it down like this.
The problem are the mainstream banks, they don't like Crypto-Currency and cause a lot of trouble by closing enthusiast's accounts on their systems. A palliative solution would be to migrate to an alternative bank that is friendly to Crypto-Currency. I don't know if there is anyone in India, but that is a good idea.
Government can put some regulations over the alternative banks too, to force them to close enthuasiast's accounts as well, but it doesn't happen so fast as a judicial process starts, all parts must be heared, judge must decide... It might take years to be solved.
Where I live a similar situation happened, mainstream banks didn't want Crypto enthusiasts anymore on their system, but it wasn't so easy for them, a judicial process started and they had to give the accounts back to everyone, including the exchange bank's account. But it's always an unstable situation.
