I did a little research on this for a job last year and internet access/mobile phone ownership numbers are far higher than I expected. Mobile payments are already a very common form of transaction in Africa. The Gates Foundation mentioned that one of the big issues with their current infrastructure is middle-men fees when talking about remittances between African countries through to mobile credit, so crypto is actually a strong candidate to improve that area too.
