I always rely on these things before investing in any ICOs:
1. Make sure that the project's identity (description, roadmap, SC&HC, etc.) is not shady,
2. Make sure that the team's background is clean and clear,
3. Make sure that they have enough social media to promote their ICO (additional value if they advertise their project),
4. Check out the team's responsivity when dealing with the investors,
5. Check out the ratings of the project on the rating platforms,
6. Ask your closest relative (who has already into crypto for some time) whether to invest in it or not,
7. Have strong faith and clear mind
