Can't Nigerians open bank accounts in a foreign country? Why did you need cryptocurrency to achieve your goals? I can only imagine it's easier to pay for life's essentials with a debit-card issued by a UK or Dubai bank in Nigeria (or cash withdrawn from an ATM using the same card) than it is to pay for those same things with Bitcoin there.
