A lot of figureheads in finance and the business world have been talking about Africa more and more as of late. If you use a similar template in China, Japan, etc. and see how technology and innovation has leapfrogged their economies, then you can imagine what's on the verge of happening in Africa.
These figureheads are talking in terms of "normal businesses" -- i.e. the traditional businesses that are already global behemoths. Expanding to Africa has major potential for them as they tap into this emerging market.
Many people in crypto look at the potential in Africa for a number of reasons - many of them overlapping with the same reasons as these traditional businesses but many that don't align with those businesses as well.
Banking the unbanked and underbanked is a major selling point for crypto in these emerging nations/markets. There is a lot of potential to bring abundance to people who live in these places and to get them out from under the oppressive thumb of local governments.
"A recent report by Arcane Research and Luno found that Uganda, Nigeria, South Africa, Ghana, and Kenya are frequently among the top 10 countries by Google searches for the word “Bitcoin.”"
Clearly, there is interest in a global, non-sovereign digital currency that is transportable and deflationary.
"The firms emphasize that Africa exhibits a young population, frequent monetary crises and currency failures, large unbanked or underbanked populations, and expensive means of payment."
I think we're just at the cusp of what's possible with digital currencies and stores of value like Bitcoin in these emerging markets. There is opportunity for people like me who live in America, but the true abundance is for those in these other places of the globe. For me, crypto is a nice-to-have. For them, it's a need-to-have and I believe that they will be exponentially better off with these technologies.
