Populous has a business model explained in the whitepaper, source code, full disclosure of who is on the team, a bunch of pictures in their office, don't run an ad campaign to sucker you in, and at least 1 person that has described how the business works in a video. They're more transparent than coins valued higher than their's. If nobody is fudding a project, then there's probably no reason to own it because nothing new is happening. Maybe that sounds counter-intuitive but all good investors that made money on something were probably challenged to dump the coins/stock at some point.
