Op, from the look of your account, you are also a newbie who is calling other people newbies. From your post, you are right that many people have been losing money when it comes to doing P2P on some exchanges because scammers are everywhere.
Hahaha it may sound funny but many newbies in the forum are not actually newbies in crypto related stuffs, some have gained experience outside the forum but are here to enhance it so maybe the OP might fall under the category of those that are not newbies to crypto related things but a newbie in the forum. Well i don't doubt that anyone can be victim but it's mostly someone that our people call JJC (Johny just come) in crypto that would fall victim to those dubious P2P merchants, someone that's very knowledgeable and know how to use exchanges or have been trading with the P2P for long would know how to deal with P2P scammers when they encounter them.
