Africa needs a big help in terms of financial if I am not mistaken they are one of the modest countries, the adoption of bitcoin would be a great idea for them but I don't think that it would be easy for them to adopt this kind of currency if you mean that bitcoin as a standard currency or by just using bitcoin, both things are hard to implement, especially if the first one that they are going to make the bitcoin as their standard currency, implementing that kind of things is not yet existing even for those first world country.
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 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
Well said, before the help of other people or other countries, you should help first yourselves, make something to change your life and one thing that could be your source is knowledge. Be knowledgeable in every aspect makes you a great person and can lead to a good country.
