This is an example of the scam:
Alert: Latest P2P ScamSomeone told me it happened to him 4 times out of 5 times he exchanged bitcoin to naira this month alone.
You may want to exchange ₦68900, the scammer will send ₦60900 thinking you will not know. That is how the scam is. If you send the scammer message, he will do as if he did not know that it is a mistake and send the remaining amount.
I knew these does happen but, I couldn’t imagine it to be too frequent. What I encounter the most is users getting to bargain in a bid to beat the price down. It really pisses me off to have them haven’t set the price previously, you pick them and they end up trying to get you against your will and plan.
I have had to report a lot of these in the past but, you really don’t get to see the effect as concerns, exchanges having to hold users to their responsibility
