Actually, like ICO rankings, it really helps us in making project choices. However, we also have to be careful and do re-research. Some of my projects were successful because I got them from the ICO ranking website. And of course I checked it again, so I didn't get a fraud project.
doing repeated research and looking for deeper information is also important besides the Team that follows the ICO. teams that already have good achievements will find it easier to find opportunities for success. if the team is famous and knows everything, it will avoid fraud. Believing or not being there for anyone is your right so it's up to you
