I guess they have a crappy currency, even crappier than currencies like the dollar or the euro, and people get by as best they can. Apart from being extremely useful for the unbanked. That makes sense. From what I see on the forum, something similar is happening in Nigeria.
I have found that it is the biggest slum in Africa and third overall in the world. It is even said that half of its population is unemployed while half earns less than a dollar. It seems like they are in a bad economic situation so to speak. Putting this in mind, we would understand how it is much better for them to use crypto to keep the value of their money instead of letting it fall victim to their own inflation rate.
