If you intend to invest in Altcoins such as ICO or IEO. I guess you should actually do the analysis. Some points that you say are correct to check out the project ICO Tau IEO.

I will try to add some suggestions? Check the project objectives. Projects that have unrealistic goals often end in failure. You should also avoid projects that have negative comments. Follow a community that supports the project, if it has a lot of negative opinions, I suppose this is a bad project.
