We don't even need to ask why Dangote is not using or investing on Bitcoin because is simple that he doesn't want to invest on Bitcoin, however how could you expect a businessman to go and advice the nation why they need to have a Bitcoin reserve, he could obviously be putting his business at risk considering the hatred the government has for it, so even if i was in the place of Dangote I will keep my interest on Bitcoin very private because if you create an awareness that would influence the government ethics they will bring your business down before you could even think of that.
On point, that is why most African businessmen do most of their work private and people might just be thinking one aspect of life that is producing the money, not knowing that they also have another means in which contribute to their wealth secretly. That is why they said’ Don’t judge book by its cover’.
So most business owners makes more money from investing in bitcoin, but they won’t show people the other side because of their reputation or the risk involved just as you said, even some of our leaders might be doing the same but be pretending that they don’t want it but deep down, they don’t want bitcoin to go away.
