I don't believe in crypto ratings sites because most of the ratings may be fake by those behind the project, The project may be scam and pay the listing fees for the ratings site to deceive investors. These sites may be useful if the investor uses them to know the accurate information about the project and to know the activities of the project's social sites media and benefit from the answers of the project team about the questions and concerns of investors.
I agree with you. It is best to carefully evaluate and observe the community of the project because if they have investment needs then they will surely have many questions for the project. I am very good at analyzing which projects are potential and which are risky so nothing is too difficult for me. However, once you invest, you should accept that you may lose money at any time because no one can predict what will happen.
