Do you know that some newbies are really not newbies? They know better than some high ranked members and is really hard to tell who's really a newbie because these days I believe members are on disguise just to play a game of hide and seek, like not letting out their identity.
So in this case the suppose "newbies" have the knowledge of either trading and other stuff you think they're suppose to learn, and learning is for everyone no matter your rank, a newbie can educate you on what you feel you know much better.
I agree, some people have very good knowledge of trading but they didn't sign up in this forum, when they create account so we will call him newbie (in term kf Bitcointalk) while he has a good knowledge than of crypto and investment ideas more than a legendary. I think the best knowledge we could learn is from our practical experience and newbie with could gives advice on trading according to past experiences (either lost or win).
I agree with this point that newbie should focused more on learning more than a teaching and once he learned well then he will be able to gives correct advice and will not mislead others but this is only for those newbie who has no previous experience.
