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 only consider one merchant when needing bank account details for international bank transfers, for example, if I want to receive money from my client from Brazil, I immediately login to Noones formally paxful to create such trade from my regular customer on the platform, I do this by contacting him on Whatsapp first, but I never fail to run transactions on noones because I might be scammed no matter the trust I've had on him.
If I'm trading Bitcoin, I don't have a particular merchant, I only use the merchant available on the list.
