Before executing a trade in any p2p platform, there are several notice and warnings including videos and disclaimers on how to use the services. Part of the core message is usually to ensure funds are received before crypto is released. Anything contrary to this sequence, there is really little the exchange can do to help as it will be difficult to prove funds were not received.
Following instructions and being cautious is the sure way to survive in the digital world because where there is ease and comfortable is where risk creeps in.
This is why I like most p2p platform, the pop ups and guides that shows when you want to make transactions reduces the level of which releasing of funds can be done. Most times I get in a rush and would want to finishes some transactions so fast but i cannot skip those pops ups and questions and to be sincere it has saved me most times.
