An interesting thing to observe is that in some exchange INR deposits and withdrawals are still working like Unocoin. This means that all banks have not followed the RBI circular. Even Zebpay just paused before a day saying that it is following RBI notice. The exchange did not mention if it got any notice from the banks it was using. This means that banks have actually not got any official letter from RBI to impose the ban on 5th July.
