It has been explained by the OP in main page of thread, but i don't know if it is your method or experience before investing into the ICOs projects, personallity i choose the ICOs projects based on the new innovations in the blockchain of technology, the experience of Dev team, the products will can be used by all of the communities and the reviews of another users about the ICOs, usually it can be found on the official thread or social media.
