You are absolutely right, during this long bearish season many many good projects died forever and some leave during the initial coin offer. The crypto market is unpredictable so far.
We all could predict the future of trash coin, mate. Honestly, almost the ICO projects from 2017 till today died. Of course, that included hype or large projects like Eidoo, KickICO, Civic, Bancor, CyberMiles, AirToken, Etc
We saw what will happen for all hyped projects. We even know that ICOs or IEOs are just trapped cakes created for speculative markets. It's just that people forced themselves to forget those things before speculating on ICOs, IEOs.
