i have never seen anybody say that genuinly. people who say it are either FUDsters trying to manipulate the minds of newbies for their own benefits or are newbies who are repeating something they have heard by the brainwashers.
in some cases when they say it they are targeting the altcoins which makes sense as a lot of them are indeed scams created for fast money grabs from the newbies who don't know much.
Yes, sometimes I see that most groups on Facebook always tag and make people use their references (especially in the groups I follow), I don't blame them, but most of what I see they give references to websites which can be said to make personal profit.
