There were many projects that had good ideas, but the team lacked either knowledge, or the means, perseverance, to bring the matter to an end. But Potentiam fellows, do not give up! ...
Well the question is if the Potentiam team actually posses the very qualities you mentioned above, Yes, there are alot of project currently in the market that has brilliant idea on how to use blockchain to bring service to the community, but, do the really posses the dedication, patience, commitment to make project successful?
Recently you hear cases of internal conflict and Exit-Scam case among dev team which is rather sad so to speak
I don't think at present there are many project that are in this field, so hopefully many will find this project useful enough to participate.
