Certainly there are sites for rating ICO, But you can not rely on them completely, Because you will find projects that have been cheated in their rating by paying the money, I also prefer IEO more than ICO because ICO has shown a lot of scam projects in recent years, Click on this link : (https://icorating.com/analytics/indepth/) I prefer an icorating site and you can find projects that are stable for investment and risky, You can read the report of the project you wish to invest in, but you should do your research on their whitepaper and what they have achieved for the project and their team.
