I doubt if this was available on Binance when it was still allowing Naira P2P.
Binance has floating price but if the the ad owner change the price before the order is opened, it will always take you back to the lists of available ads to choose another ads, instead of asking you to proceed. This is how it is on the centralized exchange that I am using now also. So I will say Binance was not having the scam feature.
Bitget belike e no dey allow Nigerians to verify their account again because the last person wey register been updated me say verification dey suspended when him try verify him identity.
I was able to get registered on Bitget the day I created this topic.
