I will only believe in the ICO that has been collected up to SoftCap and has a very useful project and can even be one solution to many people's problems.
I also go to these ICOs as I know that if the project has collected the softcap then it will complete their project but along with that we have to look at the developers that how much they are working for the success of their project and that how much there is potential of success in the project.
