I believe Bitcoin was intended to spread the wealth. Decentralization is the keyword here. To read about Bitcoin being adopted in poor economies is heartwarming. To allow countries that have been exploited and or deserted by centralized authorities to have an equal footing in the global economy really makes me optimistic that Bitcoin and its community is really doing some good in this world.
Africa is suffering from unemployment and poverty. Bitcoin would be a good selection for them to increase their wealth maybe. So it's as expected when they show a great interest to bitcoin.
