i dont think a low marketcap or a low coin price is an indication of a good project to invest in. However, i can see some patterns in doing so. In my opinion, i'd rather assess the project through a business standpoint and make my investment. Things like working MVP, elite team, existing community and especially an existing company prior to their ICO/project. Projects like KOZ, Rise and BitTorrent are projects with existing companies and teams. Which i would rather put my money in than a random team formed for the project.
