Do you guys use ICO listing to find an ICO to invest in or is there some other place to look for one? I just don't think I can trust ICO calendars so much.
You are right, you should not 100% believe in the trackers' ratings.
Try to spot what signatures are used by high-rank users on bitcointalk as make a list of 10 (for example) projects they promote. Then, follow and check the selected projects more deeply. Check KamaGames (in my signature). This company has already had a huge audience of payable users and generate a lot of income. Now they are launching token sale - join.
