as a newbie I don't suggest you join in any ICO because even some good ICOs turn out bad after listing like sushiswap , Only very geek and professional guys could tell that, You can follow some of them on twitter , I am following @mandyb on twitter and he is not bad.
Yes, but basically everyone who is a professional also comes from a newbie, so following in the footsteps of those who are already professional is good, but learning to understand yourself is also needed, because those who are professionals have also been wrong or deceived, both in seeing and in understand it.
