When I asked about opening a current account for crypto trading they said you need to have GST tin number for having current account so literally you cannot open current account in India for crypto trading and also RBI said your account will be blocked if you are using it for buying or selling cryptos.
You can't open even current account for bitcoin trading because bank transactions is barred for any transactions of crypto.
That's why mostly exchanges closed in India.
Yes I did explained the same thing in my above post but you know faking the documents in India is not a big task so people who can use their current account for bitcoin trading and can use other documents for filing the taxes.
