What's the most convenient way to do so? I guess local bitcoins? Are there any automatic exchanges left that can directly transfer to the bank account or any other INR wallets?
The days of automated exchanges in India are over when the RBI forced the banks to close the accounts of the exchanges running in India, you can sell the coins in Wazirx and trade the USDT in their P2P exchange and it straight forward and that is the case with Local bitcoins and Paxful.
There are other options too
I am yet to trade in Giottus and Remitano but giving you the options to trade in India.
