Bitcoin has generally gained in value, and may be a bit volitile, but is extremely stable when compared with their currencies that experience hyperinflation, and are re-issued, and changed completely with each new warlord who takes over.

Bitcoins can also be sent back and forth between first world countries and back home in africa basically for free, allowing the one family member a family has working in America, or some European country to send money back to their families, without paying the huge fees they do now with existing money transfer methods.
