I happen to stumble on the bitgold site, just like the bitcoin site where you invest your money in gold per gram and you watch it grow. The naira equivalence of your gold is displayed in Naira which you can claim as you reach 1gram of gold. You get the value in Naira.

A new feature was just added, which is the bitgold prepaid card, which is just like the payoneer card where your gold value is deposited and you can useit anywhere in the world where master card ATMs are accepted.
Though I have been on the platform since August this year, I wasn't too serious with it untill lately.
To register, please follow my link and register through me, this way you are credited with some gold and I am also credited and it grows from there, you can also invest some money depending on you
