I think Africa is beyond help. I am an Egyptian and I live in Egypt and I can tell that few countries here can use a help. Most of Africa's countries want something more sophisticated than just help. We Africans must help ourselves first. It is a very rich continent but all of its treasures are wasted away. Leonardo DiCaprio's Blood Diamond was a good example. So early for blockchain here.
Except for South Africa
No place is beyond help. Everywhere can improve if the people work hard enough at it. I am reminded of a quote from Andreas Antonopoulos that speaks well to this topic " “Does that mean that Bitcoin will always be the de facto Money of the Internet?” he asked. “No. What is special about Bitcoin is that it represents the open blockchain. […] It connects the vast number of underbanked, unbanked people around the world; some 4 billion people who could become connected through a simple Android phone or even a simple Nokia text messaging phone to the global financial network.”
