Probably the way to do it would be to go to a place outside India - a conference with a local meetup (can check meetups.com). Offhand based on your location, Seoul, Philippines, Bali, Taipei off the top of my head have local BitDevs/BTC communities, and active events. It sucks to have to travel, but you can do P2P trade and then importantly get into local chats/groups of BTC communities. I have noticed that there's a tendency to sell non-KYC sats for cash, which can be harder to finagle, but some people are willing to take international payment rails like Wise/Paypal, not sure of the status of those in India. Also most people in BTC communities are buyers not sellers.
