What do you mean by this? Coz you're basically telling us that Scams are scams, but not Scams are scams.
Because there are so many sides to investing, we have made a lot of profit. In many cases, those who try to get up and down quickly are scammed too, so we need to trade with the good guys and see how many opportunities there are. And those that should be exchanged for good and popular side are less scammed.
Investment can be in many form, here in cryptocurrency you need to do your own research where you could get the most of profit you want in any coin. I'm not really a fan of p2p exchanges, I don't even use Paxful although there are people in here that says it is a good exchange coz the fact that it is a p2p already worries me. I know nothing about the vertex but based on what the majority it is a scam exchange, maybe the OP did just encounter an error or somewhat a bug.
