M-Pesa has nothing to do with cryptos and bitcoin, and the whole " Countries in Africa adopting cryptos" is such an overhyped theme people are getting bored of it.
Since I don't really follow world news, I wasn't aware of the M-pesa thing in Kenya, so that was an interesting read (even though I despise CNN).
I do agree that many countries have problems that won't be solved--or even helped--by bitcoin. And you've got to ask yourself how a crypto as volatile as bitcoin is can help anyone living in poverty. Sure, there are individuals in Africa and other impoverished areas of the world doing jobs like signature campaigns and the like, but I don't think any of them would choose to hold bitcoin over their local currency--unless they're doing it strictly as an investment. For the average African, I don't think that's going to be the case (though I could be wrong).
Keep in mind that bitcoin isn't even 10 years old. For a form of money, that's pretty young and it takes time for something as unique as crypto to gain acceptance--and even in the 3.5 years I've been into it, I've already seen advances as far as new merchants accepting it and an increase in popularity in countries like the Philippines. With Africa, I'm sure it'll happen eventually. I just don't think it's their priority right now.
