I don't know about your experience with ICOs but that is not all correct.
I think although the number of scammy ICOs are high, it should not be too high that no one should ever invest in an ICO.
Also doing a research on ICOs is actually not that hard.
When you know how to do a decent research, I think it should only take you about 2 hours to get enough in depth information about a project. Is 2 hours a lot to understand a project? Not at all.
2 hours, are you sure? so if you are serious then in one day you can research 12 ico, amazing.
I think you have successfully invested in each ico, therefore give us suggestions or ways to maximize research in just 2 hours. help us, share your knowledge and we really appreciate it.
