If some website says its a scam, then you should investigate it further and see why and how they concluded it. Used your common sense. Its hard to tell if a ICO is a scam unless several red flags is raised, like the team behind, whitepapers their roadmap, etc. Maybe this is the reason why coinanalysis.io. If you want to be really safe then don't invest on it. Simply as that and go on the next ICO.
