Yes this is the main qeustion...i think africa still the last continent in in term of bitcoin and crypto, Regardless the country the majority of the population has not even heard about bitcoin
I don't think that you get the situation here. Africa is one of the most well-aware countries for the matter of Bitcoin. You can easily see on Google Trends that the most country who searched for the keyword Bitcoin is mainly African countries (ie. Nigeria, South Africa, & Ghana). Although, it is indeed true that this doesn't include most of the countries in Africa, which there is 54 in total, which means the majority of the population have no idea about Bitcoin. However, the OP here stated that his country is listed in the top 5 African country that uses Bitcoin. So basically, it is safe to assume that the people in OP's country are quite familiar with Bitcoin.
If in the OP's country, bitcoin really is very well known, i think its more profitable for the OP to have a business that accepts bitcoin instead. As of the moment, i don't think that having an ATM intended for bitcoin will be profitable enough not unless you banks accept bitcoin in your country.
