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.
