If you are really looking to find a scam, the elephant in the room is Dash.
The dev premined boatloads due to a 'mistake' and he didnt fix it because the community was cool with it

That seems totally legit.
I like how the Dash [ANN] thread's cult enforcers are so quick to attack anyone who fails to cheer loudly enough for their insta-mined, completely centralized scam coin and associated Masternode HYIP.
The way the DashHoles report and remove on-topic posts that aren't sufficiently positive really makes me believe they are a mature, stable community with nothing to hide.
My favorite is when you bring up the instamine, "...But look at the innovation!!!"
You mean innovations like X11, which is flawed and Evan has yet to answer how he intends to fix it. Or innovations like darksend (admittedly second rate anonymity by Evan himself) with its 20+ hour mix times.
And don't forget instantx, which TPTB_need_war demolished so badly that Evan has yet to untuck his tail between his legs and comment on.
Hey dashtards, adding a dark to something doesn't make it anonymous anymore than adding x to something makes it innovative.
