Countries in Africa will probably need bitcoin to help them improve their economies. There should be a common currency for these countries, bitcoin is very appropriate, but their government needs to cooperate with developed countries to change the economy.
And that is even possible to make happen by introducing Bitcoin in the continent. The ratio of people living below the poverty line is very high and this lead majority of them into crime and many illegal activities and many of them end up in jails or in worst health and mental condition so it is a dire moment for introducing Bitcoin into such low income people who might be able to use it for their welfare and to improve their living standards.
