It should be quite clear to astute observers which coins are on such a [pump-and-dump] trajectory.
Maybe. One part of industrializing the process means getting better at selling it (if only because competitive pressure means the better scammers survive, but also learning and economies of scale). This happens in every speculative market -- over time scams get more professional and harder to identify.
Yeah Auroracoin which BCX identified as a clever scam (holding the 80% premine on behalf of the citizens of Iceland) and helped kill.
This only matters if you are trying to sell your coins early to pay for project and/or living expenses. If you try to do that, you look like a scam, and the market won't reward you (unless you can time machine yourself back to late 2013). If you don't, the you are stuck with the rich people problem.
Unless of course your target market is not BTT, so you don't give a fuck what they think. Let the astute ones join the ride if they want. And your target market aren't investors, so they don't even think of that.
