I think a cryptocurrency could bring some stability into their economy. I'm talking about the poor African countries with weak currencies like Zimbabwe. Currently 1 USD equals 360000 Zimbabwean Dollars. When your local currency is worth less than dust you should consider switching to something that won't disappear with another putsch.
Well and i guess their leader is so obsolete he might probably not have heard about bitcoin. I will rather encourage the youth of such African countries to get open up exchanges and start trading cryptocurrencies locally to help push their economy into the right direction through the foreign exchange they receive through bitcoin.
