I have experienced this on a good number of exchanges and I don't see it as scam.
Do you have a Bitget account and have tried crypto/naira P2P there? I have used over 10 exchanges just for P2P before. Go to Bitget and understand what I am talking about than to disagree with my what I said about Bitget. The exchange is full of scamming ads as a result of poor rate algorithm the exchange is using. I have seen people that used floating rate on other exchanges like Binance, Bitget etc cetera. If the price changes, the exchange will take you to the exchange P2P page to select another offer.
I dont like being drawn to arguement like this but will freely tell you that I have been using their p2p for quite some time and more often after Binance removed NGN. Like i said in my earlier response " there is usually a pop up message that gives you a window to cancel or continue with the order", I am not sure if saw that pop message but that's how it has been and i think it's similar to that of Binance when NGN p2p was still active.
