Or why not just stop investing to ICOs and just go with the normal tokens / coins that are already listed on exchanges?
Doing research is still good enough to know if the ICO is a scam or not that will give you strength on what to avoid.
It depend to the investor could not trust the Ico's and they are spend there money to invest and earn income. If you want too avoid Ico's that will scam in the end. try to research about the whitepaper and project profile if the Ico are good and legit.
