That's just one type of credit card here in Canada and there are dozens each with different benefits. The sad thing is our card benefits aren't even close to how nice the ones in the USA are (they get ones with benefits like 5% off on everything) or $300 for signing up and more.
Sad to say but in Nigeria I think you get the worst credit cards I've seen (sorry, but I think there is a reason no-one there uses them). Having said that it seems like some of your prepaid cards aren't bad as the fees for them are much less than they would be here in Canada and if you can have them personalized with your own image for inexpensive fee that would make them something that we can't get here in Canada.
Imagine: If you can get a 30,000 Naira prepaid credit card which needs PIN# to use.
Imagine: You can put a HIVE or Earn, Spend, Give logo on it for cheap.
A person anywhere in the world could "order" it with the GLD token and a cool looking card could be sent to them (letter post isn't that expensive for small envelopes). Even if it is denominated in Naira it could be spent anywhere and the PIN# means that if the card is stolen the thief doesn't get the money. Just freeze the prepaid card and the 30,000 naira would be safe--or you could use it to buy another prepaid card.
...and yes, not getting stuck in debt is crucial
