You forgot to mention one exchange that is currently in Africa and that is Luno. They offer their services to some African countries and I can remember they launched Im Nigeria last tow or three years. Heard that users of the exchange can easily buy and sell cryptocurrency, another thing being that they can also withdraw straight to their banks. I believe there are also many of them available and offering their services in Africa.
Thanks. I've looked at their home page (I think you meant
https://www.luno.com) and they have a base in Cape Town, so they could qualify for this list. In February I plan the next update for the list, will try to investigate a bit about Luno's launch in Nigeria and other service providers proposed here, and try to find new ones.
