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.
I agree, it's a great way for people to find job opportunities outside of their own country. There is no language barrier once you learned English and also geographical borders are not going to be an issue as everything is done online. Maybe some special crypto courses for people in Africa could help them to take advantage of the new opportunities.
