I'm not sure what you mean by saying Africa, as far as I know, there are more than 30 countries there, and they may have different situations with cryptocurrencies in one country you can see they legalize cryptocurrencies and accept cryptocurrency payments while in other African countries you can see the government won't allow the cryptocurrency-related transactions as an example I think in Nigeria the government started to take hard of cryptocurrencies and bitcoin while there are many bitcoiners and cryptocurrency investors there.
You are right there. The op needs to be more specific with this but upon my research, I found out that there are 54 countries in africa. That's a lot. Didn't knew Africa is that huge but like the op I also mistaken Africa before as a single country. People on Nigeria is going to have a tough time now that the government in their country are now after cryptos.
There is a post here last time which said that binance is going to have a project in one of the African countries. I forgot if which specific country was that but it's a good news for them. Binance one of the largest crypto exchange also see the interest of those people towards crypto so they are helping them.
