Built a lot of blockchain ? I would like to know where you possibly got that news from in the first place to at least verify that you are not just saying what you feel like. It is one thing to be considering the aspect of knowing how to use cryptocurrency and it is another thing to even seeing them adopting blockchain pretty fast. Something they do not even have an understanding yet.

Yeah, there is no doubt some few blockchain businesses have popped out from the ideas of some youths in Africa. At least, I know of Kora, as well as KubitX which are not some bad projects which I bumped into, looking for some ICOs to invest in. However, there is still so much to learn generally before we would even be able to see the whole continent at large getting to adopt cryptocurrency, let alone, blockchain technology.
