Truth be told, in Africa we see bitcoin as an investment rather than as a medium of payment. So, we acquire it and then wait awhile to resell it like a real estate. In Nigeria, I am yet to see any shop accepting Bitcoin for payment. One has to exchange bitcoin first into fiat before any payment for goods and services.
I think almost all countries except those that prohibit bitcoin, using bitcoin like that, it is very rare that bitcoin is used as a means of payment, only as an investment tool
