Are you for real? In Nigeria, it is rare to see someone using Bitcoin for daily expenses because not all transactions can be done using Bitcoin due to transaction fees. It makes more sense in the part where you use it for cross-border transactions.
Another thing, name one shopping mall that accepts Bitcoin for mini transactions. Except you are buying a product that cost high and if the vendor accepts Bitcoin in Nigeria.
Baba even me I shock. Most businesses in Nigeria, don't accept cryptocurrencies. So it would be difficult to use cryptocurrency for daily transactions. Using it for trans border trade sounds more thoughtful since it would save costs and promote privacy.
In my area, there is no single business that accepts Bitcoin. But there might be some in highbrow areas of the state. I cannot dispute his claims since I don't know his location in Nigeria.
For OP, na money make me buy Bitcoin. As the price increase, I dey sell am use the money to invest in other things. I also plan to keep some as an inheritance for my dependents.
