I don't know why some people trade P2P. especially when they use a platform like Binance. there available for spot trading. it's quite easy to convert the crypto we have to make withdrawals.
Personally, if you do a trade like that, of course, choose with the best reputation and reviews. especially those who already have many successful transactions.
I do not use P2P on any platform for crypto transactions. but I've done it personally for payment of goods with people I know.
Traders that transact using P2P on The Exchanges are mostly from countries where adoption of bitcoin and cryptocurrency at large aren’t rampant. physical P2P might seems risk less but that a locality where you had hear of any trader then one just has to trust the exchange P2P to convert coins to local fiat.
I normally use Binance and KuCoin and I consider rating and the number of transactions that such trader has done in the past. Then as human greediness will have it I also look the amount of each trader. But the later has thought me bad lesson because I once transacted with a trader on KuCoin with a rating below 50% and it took almost an hour, and I was seriously in need of the fiat and I couldn’t terminate the initiated transaction and just had to wait. So rating definitely matters a lot
