You don't need one in your country as you can't add funds to a balance in your country OR receive funds into a balance.
The option to receive Paypal payments is sadly not available in Nigeria.
You can only send payments for purchases funded by your (confirmed) credit card.
Paypal varies a lot country to country and can only offer the services that the banks / governments of that country allow it to offer.
There are quite a few countries unable to receive Paypal payments.

Kudos / Solution appreciated.
