Bitcoin could lead to a new economic revolution in Africa, because there are a lot of reasons people use btc instead of there national currencies.

Zimbabwe is one of the countries that using bitcoin more often that their national currency because of the more potential of bitcoin rather than their sinking currency. If bitcoin will be 100% implemented in Zimbabwe, i think that their country can be saved by just working and saving bitcoin.
