Isnt one of the main problems in africa endemic corruption causing currency problems? I think any kind of crypto based system would be welcome there for that reason.
Absolutely. One of the reasons I got interested in currency was to have experienced first hand in the mid 90s in Khartoum what hyperinflation was doing to the day-to-day lives of the Sudanese. The story I most vividly remember was our driver explaining that nobody really knew when the army was going to get paid but he and everybody else in ordinary jobs just had to hope the army's pay would not come before their own. Because as soon as the army was paid from money that had been printed for the purpose the school fees would double and so the timing made the difference to our driver of whether or not he could keep his kids in school for the next month.
At the time I'd just learned about the WWW and was really excited about the potential of the wealth of hyperlinked knowledge and communications to break the power of abuse that was held over those people by their government (and to a lesser extent, all of us). Now with the combination of smartphones and crypto-currencies it seems like there's only a small step to be taken not only to lift a vast number of people out of political tyranny and the poverty trap but to release their creativity onto the world. 'Scuse me verging on the hyperbolic but with so many more free and connected thinking people we have no idea where mankind can go in the forthcoming years and decades. I feel it is a privilege to be alive at this time to witness what I believe we're about to.
