No offense OP but I actually before joined a 99% similar project before in 2017 and they actually did raise money but failed. And I believe they have been a few others using this mesh network thing to try do ICOs.
But until today, there are no blockchain mesh project working in Africa like the way described. Why are you different? And are any of the devs African because that is super important:)
Hey Leea, good question. There was a blog article released recently about this very topic:
