Kotak is strict on crypto, they sent notices, calls to consumers for suspected transactions, even when you register they tell to not do any transactions in crypto
Won't be surprised if they closed the accounts.
How about the customers who are having account before they added this disclaimer.
Disclaimer was for awareness's sake, if rbi puts a guideline, does it matter when you created the account?
my biggest doubt is that how are they going to determine whether someone is dealing with bitcoin or other assets, either they need to create a separate wing to monitor those which is expensive as it is not that easy to monitor those unless they want to monitor and question every transaction and how they are going to provide a proof in court when the case regarding it is still sitting in Supreme court.
Some people put crypto remarks in crypto transactions(mistakenly/deliberately idk), this makes banks aware of it.
And quite possibly, if you linked your bank account to zebpay/etc when there was no rbi ban, then they can suspect that you used to deal in crypto and might still be doing it.
