I agree with you for the most part, though I wouldn't call putting external money into steemit being scammed as opposed to making a bad investment. However, as investments go, sometimes what seems like a bad investment can become a good one. I don't mean to come off as one of those people that expect every new cryptocurrency to become massive successes, but I think it's a little early to say whether or not the time is worth it.
