Wetin fit be the possible dangers of doing P2P transactions with only one merchant for these centralized exchanges wey still dey function like ByBit, Remitano and the others? I dey curious because aside say one or two small price difference in kobo, e get any danger? Now, nor be say the transactions dey happen out side of the platform, e fit be say once you don trade with the merchant before and you come like them based on their price and how fast dem dey pay, you decide say anytime you want trade you go contact them to trade but everything go still happen inside the exchange just to dey safe.
I think it is even safer if the vendor is always active to attain to you, then I think there is nothing safer than trading with only one vendor as far as the vendor is given you good rate. There will no further risk of losing money to any vendor which usually do happen because some vendors will not respond in time while some vendors will also claim he/she has sent money, but you didn’t receive the money which is usually painful until you end up appealing to the exchange.
However, there is no completely reliability to any vendor because most of them are anonymous, we don’t know them exactly since we just meet in exchange to have transactions that will benefit each other; relying on them is risky in general.
