It is impossible, africa is quite outdated, only those countries that are rich in there can afford a good living, and access to the internet.
I don't know much about Africa but from what I heard and know, it is a poor country. They are struggling with poverty because they lack resources such as food and water. I'm guessing their lack on the bitcoin uptake is because of this. Before going into bitcoin adoption, I imagine that their government should first focus on alleviating the poverty and coming up with solutions. They should do something about their resources since they lack in food and water.
