I just notice say for Bybit some vendors they specify say there payment method nah cash in hand, abeg anybody don try out this option here ? 
My brother, to tell you the truth, I really dy surprise say person go even put such payment option for him adds, because to me once you tell me such, I don see you as a scammer, because the question I go ask myself is wetin happen to bank transfer wey person go come they talk say him go pay through direct payment physically, so the security risk dy too high for anyone to even agree to such.
Another thing their is distance, if me wey dy stay for port Harcourt, how e dy possible to take such trade from person wey dy stay for lagos? So to me, e no make sense in any way, na just stupid options of scamming strategy by these scammers, because I dy sure say no body in his right frame of mind go agree to such deal.
