There is a well known method for ICO investing: do your own research. In the previous year once I've been asked to help one ICO to send some e-mails to different ICO related websites (including listings) and I've discovered that a pretty big part of the ICO ratings are require payments to get your project listed on their website. That comes especialy about the local websites. The mail nesson was that ICO ratings can never be 100% trusted. Ofcourse they may show the grneral hype around the coin but you should always make your own research.
