Bitcoin could really change the lives of people in a certain country because of the opportunities that it offers. Africa is one of the neediest countries and it's a good thing that they could consider Bitcoin to eliminate poverty. Despite all the risks, if they will be able to adopt the importance of trading and investing, it will help decrease the number of poor people in their country.
There is a reason why Africa remains as the poorest continent. If the governments want to alleviate poverty, then they need to look in to these factors and do the required. I am talking about overpopulation, ethnic violence, lack of education.etc. Bitcoin may help to some extent. But it will be of little use unless the basic factors are taken care of. What is the point in promoting the use of Bitcoin, if the population doesn't know how to use them?
