would you agree about the countries involved? are you interested in moving into these countries or starting a business that is crypto related? also there is no country from africa in the ranking. could there be one in the future?
Most countries are crypto friendly so if your country doesn't frown at those who are into cryptocurrency then why the need to move to another country? except that crypto is restricted or banned in your country and you are a crypto enthusiast then you can move to a country that is crypto friendly. For the fact that no African country is there in the ranking does not mean that African countries are not a destination for cryptocurrency, you can do your research, and you will see African countries that are at the forefront of cryptocurrency.
