because the newbie is very new in this forum will be considered doesn't know anything about bitcoins and another digital coins
Do not judge people from their look/cover, being a newbie doesn't mean they do not know anything, they would know more than you or other high ranked member. They could be pretending to newbies, but actually they are Legendaries.
I agree with you some of them pretending as a newbie but they are high rank. If they are newbie why they know how to post in the thread, But so let them what they doing and must better try to answer the question in what they talking about.
