I agreed that Africa has been lagging behind the rest of the continent in terms of infrastructural development particularly internet penetration is still low however a recent research shows that there is a 20% increase in the number of internet users in 2018 invariably there will a gradual adoption of Cryptos as more Africans hears about it.
Africa has not been lagging behind that much as a lot of people tend to portray it, but it is also realistic to say that when looking at the general population of Africa and for the fact that they have a lot to still do with development, it is for sure something we can state.
Like you said, from research, so much is changing already as the youths are increasingly becoming a lot more exposed in most parts of Africa now. Also, considering the stunts Binance pulled off in Uganda, a place where they are even unbanked, it simply shows there is a lot of potential for cryptocurrency to thrive, as I see people who are even hungrier for it than one can imagine.
