I was directed to chipper cash some time back when I wanted to pay for something in dollar online through AliExpress. I ordered something from AliExpress and could only pay using dollar even though at AliExpress the price conversion of dollar to naira is the government regulated price.
When converting your naira to dollar using chipper cash, they’ll sell the dollar to you at black market rate. So you’ll end up paying X2.5 or X3 of the amount you’re shown on AliExpress to pay. After seeing that, I got discouraged of using their virtual dollar card to make payment online. I haven’t tried selling dollar to them, but I know the reverse will be the case. I got discouraged and stopped using their services. I don’t know or sure if on exchanges you can make payment of order online, that’s not their main purpose but if they can add that to their services, they’ll get more users and patronage.
