because on Binance you can't lose money in p2p, unless you mess things up yourself, like releasing fund before Fiat get into your bank account.
Even though you've follow the right procedure, it still has a chance the centralized company e.g. bank, e-wallet, payment provider etc can reverse the seller's fiat money to his bank account. You might able to solve that case, but it's take time, energy etc since you need to contact Binance and tell what's happened before. Moreover there's a chance you might got a dirty coins, it will harm your privacy.
Checking the feedback is important, but it's better to trade in this forum with a trusted account or through Bisq.
