You have a comfortable life. Many don't. Side note: what appears to be instantaneous settlement in fact, is not.

Someone who is not comfortable should stay far away from cryptocurrencies, because they may not survive the loss of all their money to a hack.

Someone who's not comfortable is probably facing the decimation of their native currency already, as what's happening in several "modern" countries at the moment.

What would you pick? Sketchy native currency with a near guaranteed loss of 80%+ or a volatile crypto asset?

People in countries that had inflation problems had ways to cope: back in the 80s when inflation was high there were money market funds that paid interest that kept up with inflation, for example. The baby boomers got rich because they could pay back their loans with cheap money. Inflation helps debtors. On the other hand, deflation destroys economies as it gets people with money hoarding it. If you look at times in history when national currencies we're going up in value those are exactly the times when the economy was collapsing.

I'm guessing this is pretty dependent on which country in Africa you're sending to. Probably not Zimbabwe?
