Africa is covered by demand for crypto-currencies !!!
Now Bitkoin.Africa allows customers from all African countries to buy bitcoins, quickly and without problems.
Nigeria became the first country to exchange P2P digital assets, seeking to facilitate access to bitcoin throughout the African region.
Bitkoin.Africa was launched by a team of Nigerian developers on October 1
Have a nice day, everyone!

You can check some forums here in bitcoin talk and you would see that there are a lot of ICO's that is focusing in africa. Africa has a great business opportunity through ICO's and crypto currency. So I am not that surprised with the momentum they are having for africa.
