Having faith that you'll get rich quick in a scheme is not a problem. But constantly misrepresenting the scheme is. If you bought numbers on the screen and then believe you'll be able sell them for a better price that's fine. But if you try to attract buyers by spreading lies that your numbers count a valuable digital asset, money, coins, tokens, energy, work, whatever ... that's a problem. And someone must react to expose those lies.
yes I believe a little honesty is called for on behalf of people "evangelizing" bitcoin. one argument that I hate hearing is "bitcoin is valuable because it cost $XXXX to mine". when someone says that, they have lost all of their objectivity.
