This is always a tricky one because it depends on numerous factors that are about you.
There are a lot of good ICOs out there but you need to research, spend time looking into the project, the white paper, marketing, the team and how the community is responding to them. Look for transparency between the believers of the project.
If I were you, If you find a very good project, take part in bounties first, you can earn some tokens, see how they are running everything and then once you are satisfied can invest if you want to. There is no rush to invest into a project as most projects at least run their Token sale for at least 30 days if not longer.
I would also look into Crowdholding. They are a platform where you can earn crypto through bounties / airdrops and tasks. It's free to join up and can be a nice way to find new ICOs as there are over 80 projects on their platform and it is growing daily.
