I have done some contract work in Africa, and people might be amazed how innovative some of these people are. Do not for one moment think that these people are illiterate idiots sitting around a fire in front of their huts... you will be VERY wrong.
Yes, they do not have cable internet and fiber optic connections to every house, but what they lack in infrastructure, they make up with innovative alternatives.
They have also dealt with digital currencies in the form of M-pesa running on cellphones... so you would feel like a idiot abroad, if they ask you cash or M-pesa and you know nothing about it.
The only difference between the UK / USA and Africa is the accessability of modern infrastructure and good education. The will to learn is there, but the investment capital to fund infrastructure lack behind.
The environment is also difficult, with many traditions and cultural differences, but in the end, we are all human. {albeit Robert Mugabe -- He might be a alien}
The introduction to Bitcoin might just be easier, than most people think, with their background with M-pesa.
