It is nothing bad if we criticize the new projects but we should do it with facts and evidence. Just stating 99% of new projects is scam or garbage without any evidence has no sense. We have to make research on them and share our negative findings if any.
After all it's not for ourselves, doing reasonable criticism and having strong evidence, it will help other investors know the truth about the project. This is really needed now, where new projects continue popping up with ideas that are not much different from the others.
