As long your chosen p2p platform has a good reputation + offer escrow + you've read the common scam schemes on p2p trades, you should be fine. I've been p2p-ing for fiat <-> crypto for years and never been scammed.
this are the only two legit DEX I know for p2p and so I will like to know other DEX that are good for kyc ?
Honestly, I only know BISQ. There are other platforms which claimed to be decentralized but if you look closely, they aren't so that's something to keep in mind.
I just wanna add that there are non-fully-custodial alternatives that also don't do identity verification like agoradesk and robosats. They may not be decentralized but they have taken users privacy into huge consideration.
