First, localbitcoins and paxful ARE centralized exchanges, with KYC. So, before posting such FUD, the OP should get the basic terms right.

It's true that Paxful has been a premier site where scammers hang out since it began, and LocalBitcoins can't catch all the scammers either.
We don't recommend those, because there are much better alternatives, such as for example HodlHodl.com.

The OP argument against P2P is a red-herring fallacy, because the issue he warns against is the danger of certain fiat payment types, which he falsely presents as danger of P2P exchanges.

I think all who can reason above the childish level can see the difference, but if you can't, definitely follow the OP FUD advice.

For the record, the only existing true P2P, non-custodial, truly decentralised BTC-fiat exchange is the Bisq.network, which we recommend.

Unfortunately, only 2 of the OP's "Indian brothers and sister" have even tried Bisq since it began in 2016, and 100% certain the OP wasn't 1 of the 2.
