It depends on the country and the people involved. Some African countries have not adopted the dollar as a means of settling debts or payments. In Nigeria, only a few institutions and individuals are into Bitcoin, and most of them see it mainly as an investment or an alternative to beat inflation.

However, Bitcoin can also be used for payments; whether by a country, an individual, or a household; if they choose to recognize it as such. But if they don’t see it in that light, then it cannot work effectively.
