Certain things to look for, if you are interested in ICO investments:
- Don't look for those which are either using big percentages of their distributable coins in Airdrops and/or some referral schemes (like Authorship did, that's my personal experience, and the worst one).
- Check the legitimacy of owners as well as the project, try to find someone who lives at the places these guys are from (hopefully social media could help) and ask them if they could help verify that for you (one of the toughest tasks).
- Look that they have hard cap because such ICOs with a stop are reliable.
- Try to find as much information about their future plans as possible, and don't fall for bigger discounts because I feel that those big-discount ICOs are just trying to allure you with their schemes and they are actually selling their tokens at the rates they "really" need to work out and/or scam away.
