Yes true bitcoin demand was really high even tbc there.Africans are just taking oportunity to earn and make some money because on how they live there, we all know that there is a crisis before so people are adopting everything to earn and bitcoin is one of it.If it dominates and helps to increase economy status it will be a good effect on whole country and whole bitcoin community
I have heard of TBC or the billion coins, a digital currency that is set to grow in value everday. Right now it is sold at 2.4 btc each coin and tomorrow it will be another price. But Africa is not only crazy about TBC but also with BTC and the primary reason is that it is their outlet of business not only in the local but also internationally. When they do bitcoins they are sure that they will gain some profit since the target market is not only Africa but the whole world.
