I just checked Robosats for India and zero offers for sell or buy related to the INR, you can create your own offers for buying and selling, it is worth trying for sure.

Another option will be opening an account in WISE based in UK, or Revolut. I am not 100% sure, but I believe you can open a bank account as a foreigner with no issues, once you do that, you will have a SEPA account to transact with Pocket for instance. You will be able to fund your EURO account from India using a bank to bank normal fiat transfer, using whatever is best for you.

Once you get your sats in your Pocket wallet, if your intention is to hold, transfer them to your cold wallet. If you are speculating for profit, keep it there and when ready sell it back in Pocket for Fiat
