Here are some criteria to which I pay attention:
1) the well-known in their circles of the development team, a SEO, who does not hide his face;
2) the approval authority figures in the crypto world;
3) a clear roadmap and whitepaper;
4) ratings known publications;
5) the importance of the idea and the project as a whole;
6) capitalization, the total number of coins and issuance.
And tell me where you usually know all this information? In addition to this there is a forum where you read it all? I would be grateful for links to relevant resources.
