Africa isn't "a large segment of the world economy",actually it's a relatively small part.I remember that the African GDP was more than 1 trillion USD,which is very little,for a continent populated with 1 billion people.
I think that Africa needs industrialisation first and then crypto adoption.Most of the african countries have 80% uneducated population of peasants,who can do only agricultural work.
You're saying it right.
Africa is a poor country, in which there are a lot of problems, as in the economy, in the environment, in education, etc.
But it is a very rich continent, where a large number of resources, oil, gold and other minerals are concentrated.
When the moment comes that the resources will be used for their intended purpose, as for example did the Arab Emirates, then you can talk about a large segment of the market. And so it is poor countries in which even many do not know about bitcoin.
