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.
You are very correct and that’s the best thing for him to do. If you see a businessman succeeding in his business in a country, just know that he got the support of the government to have come this far and that the government also benefits from him business very well. He would want to protect the government in his best interest and that’s how also the government will protect his in there best interest even if they can’t be trusted fully and take their own selfish desire first before any other thing you can think of. I doubt if there is a business person in the globe that have heard about bitcoin and not showed interest in it, they may be doing it in hidden but would have love to be part of it after the American government showed his support for it. Dangote can take his time but I know when the time is right, you’ll see them all running to be part of the technology.
