This is a nice initiative but the process may have some problems along the way if it becomes popular.
• This us not an exchange board, so trust score is not visible here, this will mean that someone who doesn't pay much attention can easily trade with a scammer and lose their naira or Bitcoin,
• Without an escrow there's no level of protection. Why anyone go send first to an anonymous person here when your only guarantee us they should be scared of getting red trust?
• Generating enough liquidity will also be problematic. This will be the major factor that will dissuade people.
As a fix we can have 9ja people wey won sell/buy bitcoins and have good reputation create their own thread in the general currency exchange board. Anyone interested in the service ca contact any of them and trade with them, publicly as well.
