I don't understand how a newbie with your activities no so much have you been here before?
Well the point of my post is that I have not yet come across an African indigenous site that deals in cryptocurrency.
How will you know who the operator/owner of the site is? A lot of gambling sites might be owned by African people, but they are hosting the site in countries where the internet access are faster and cheaper. Traditionally African internet is a lot more expensive and also unreliable, so they have to host their sites in 1st world countries.
Let's not be to quick to make assumptions about Africa.
