"With the AKoin we are building cities, the first one being in Senegal," the singer, whose real name is Aliaune Thiam, explained. "We're securing the land and closing out all the legislation papers for the city. We want to make it a free zone, and cryptocurrency-driven as a test market.
"If it works, we will scale it out to all the other countries in Africa so all the cities are connected. It's going to be a 50-to-100-year project, most likely. I probably won't even live to see it finished. But for the project in Senegal, we have a 10-year deadline for that city to be built out.
"We're currently raising all the money for it now; some of it will be through hedge funds outside of Africa, and the majority of it will be through NGOs and investors within Africa itself."
