Crypto + no contract or paperwork + cross border transfers
Wow, I’m surprised that you were able to go convince yourself to go through all this just to avoid taxed anr trust someone with 9 whole lakhs. You can try and ask a lawyer but with no paperwork to support most of this, it looks tough.
You might have transaction IDs but that doesnt signal intent of what the money is for. For that you would need some document where you and the friend have agreed to what the money is for. Obviously WhatsApp message conversations won’t work.
