The biggest barrier is lack of genuine spaces and environment to get to learn about Bitcoin , most young people have had about bitcoins on forumns that talks of the " get rich quick schemes " and they end up being scammed therefore losing there trust in Bitcoin or people that talk about Bitcoin. The biggest barrierto this curiosity young africans have , in my opinion ,is not being able to tell the difference between a genuine learning place and scammers who are after there money

The biggest barrier is the fiat-mindset tied to the price tag, that most people have.

1.) Poverty (no savings, scarcity mindset) 2.) Access to required technology and/or internet access not being affordable

If you were to offer to pay youth in bitcoin, even for a something like collecting refuse, most would take you up on your offer. That might be their only income source for the week, month, or year.

But even once they receive the bitcoin, are they going to hodl? They might have debts. They may want to enjoy the fruits of their labor. So when whatever income arrives, it oftentimes gets spent immediately (i.e., "hand-to-mouth", or paycheck-to-paycheck lifestyle). Thus the "selling point" for engaging with bitcoin can't be the (upside) benefits to holding bitcoin, because they know they won't be holding bitcoin for long -- just like they aren't currently holding cash.

Then for the technical details. Sure, there's Machankura, for those who only have a candy bar/feature phone, but they aren't really able to experience the same, convenient UX like that of a smartphone user with a Blink wallet, for instance.

And even those who achieve smartphone ownership, ... unless they can rely on there being wi-fi where they spend, bitcoin no longer has the cost advantage as having to purchase mobile data just to be able to spend in bitcoin makes the bitcoin payment more expensive than using mobile money or cash.

So without easy access to earning bitcoin, without conviction in the need to save, and without easy ways to hodl ... or eventually to spend some bitcoin, there's little likelihood of actually applying what would be learned to their own lives.
