Legit? I tend to disagree; most of the projects getting listed in top exchanges are only doing so for immediate profit or the hype around it and nothing more. That project gets listed on major exchanges for IEO doesn't proves it is legit, take a tour on major exchanges that hosted one IEO or the other and check how many of the projects are performing well or working according to their roadmap. There are still projects doing IEO on smaller exchanges but have a good concept. So how legit a project is depends on the team and not on the exchange it's IEO is taking place.
