There are a lot of scammers in the P2P market, and that's why, whether you're the buyer or the seller, you have to confirm that everything goes well for the other party first.

But the burden is with the seller when most of the buyers are scammers, and they'll fake it that they've paid them already.

So, always verify when someone is very active in the P2P market because the scammers aren't choosing their victims. As long as there is a potential victim to them, they'd scam them.
