I think the newbies op is referring to are the ones who do not know what they are saying. True their might be newbie in the forum who are sound in the discussion they make, very full of knowledge. Newbies who are knowledgeable their is nothing wrong if they should share their knowledge with forum members but for those who don't have Idea about about what they intend to teach other people it is better for them to learn first to share good knowledge that will be benefit of forum members, than misleading with wrong ideas.
Another thing is how can you tell who knows what he or she is saying as in sharing crypto knowledge?
You can't point out an individual that he doesn't know what he's saying, to me is best you take whatever is coming out from any newbie, take your time and process it then you check if this same guy has what it takes to even give you any form of lecture concerning Bitcoin or crypto business.
Fine, we have many who thinks they know it all but I'll always say it, no knowledge is a waste. We shouldn't forget that we have those who can't help it but run their mouth when they don't know much of what they're saying and they don't care if you're losing funds or not, all they know is talk much on what they're not suppose to, those are the misleading ones we should be aware of on the forum.
