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.
