Beginners should never make mistakes to release no matter how long it takes for them to receive payment.

Yep, this has to be written more often, since I fear that the people used to CEXs can a bit too easy make mistakes and then blame and avoid P2P, and return to CEX, give their ID to everybody and so on, when P2P exchanges should be the norm.
Before executing a trade in any p2p platform, there are several notice and warnings including videos and disclaimers on how to use the services.
True. Still, somehow people tend to "RTFM" only after they get burned. So a couple extra warning signs don't hurt.
