I don't think this is a good project worth to invest, after I read their official page and whitepaper, my first impression like to the exercises of middle school students, anyway, I don't trust any project team in Nigeria, like to another scam project. 
Yeah, OP must be shilling for where they are hired. If I were the OP and I got convinced after got answers for few of my questions, I will not invest big money like $5k (for some people $5k may not be a big money but OP mentioned it on subject-line itself hence I understood it is a big money for them as well).then i asked several other questions to get an full idea about the future plans since they havent updated those things in their road map yet and now im very excited with this project
So, it is an incomplete project or devs are too busy to complete their roadmap also? Never believe into any project just because of words. People are too smart to convince anyone by promising impossible things. I am still seeing a big red flag against your post and with this project.
