[Beginner] Need to buy Crypto P2P

I'm relatively new to the crypto world, I have gotten some knowledge through reading various articles online. But since from what I read, india heavily taxes crypto + doesn't allow you to carry forward any losses while filing taxes unlike the stock market.

I have set up my wallets on metamask, trustwallet and I want to buy some crypto. I don't want to open an account with any exchange because I want to stay anonymous and not get taxed (the whole idea behind crypto). I came across bisq which is an open source platform for P2P but there's no traffic in india.

How do I buy crypto safely using P2P in india and any thing to keep in mind while doing the same?

P.S. is trust wallet good enough?
