Yeah, actually, to believe the ICO should not only based on the ICO rating from any kinds of sites. I myself don't believe the ICO rating from Icobench and other site rating systems. We must be careful by analyzing the ICO based on:
1. COncept and presentation on Whitepaper
It is very important as we will understand about the exact project by reading and learning their WP
2. Team
It is crucial to analyze whether the team members are real or not and are trusted or not as the team and developers of the projects
3. Community channel
It can be seen from how they interact, communicate, and also share their projects in their community. It can be through the telegram channel, FB, Twitter, and other social media channel.
