If you can't find Zimbabwe in a map, if you don't know what Ghana is please do not invest in either of those countries.
Only invest in what you, yourself know a lot about. I assure you, if you don't know that Ghana has a lot of cocoa and a lot of gold please don't pay attention.
If you can't even spell Zimbabwe please don't invest there. It has enormous opportunities, huge mineral deposits, lots of agricultural and tourism in the future. But don't do it if you don't know what to do. They have a stock exchange, there are mutual funds there ways to invest but only invest if you know what you're doing.
