WE are surrounded with so many problems that any project solving any of out real life problem can be the best project of 2018. You just need to pick a problem and solve it.
Your question need to elaborate on the specific, anyway, in my opinion talking about crypto currency project, i think nothing in this project coin can solve the the problem you posted, yes, we have a lot of problem to solve, but in someway, this problem is non related to crypto currency, we have a personal, physical,emotional, medical problem to resolved or gave attention to it, still, it is individual attention to solve such problem, better yet a more specific question next time for a better discussion on the treed.
