Every time, we will find out so many shit projects that are new, with their sometimes very interesting concepts, but means nothing and impossible.
And moreover about the new hype token or coin projects, never only put your trust in them and get some investment in them because of hype.
I believe that you can find out some criteria why a good project here and shit projects there, this forum can give more.
And about to avoid the shit projects. I personally will prefer to choose the project by analyzing their WP, real team and its experience, concept, community, and also their roadmap. however, I will also prefer to choose them if they do some launchpad or IEO on the trusted and reputable exchanges.
