I am very interested in investing in ICOs and read through numerous whitepapers. What I observed is that all of them have masses of advisors? What is usually the role of these advisors? How are they chosen? Do they get paid to be advisors? How do I find out how much experiences they have in crypto? And most important, who are the advisors one can trust?

A lot of questions, I will be glad for some help. Thx.
