ArticMine, very well written and solid points. Thanks.
Explorer's answer may be correct even based on what the poll is trying to ask. In the sense that to the extent BTC is a scam (and there is not no basis for that) it has scammed more people for more money than all the others combined.
ArticMine's point is also valid. There have been more blatant scams than Dash. Then again we never know what is really going on behind the scenes with any of these coins (i.e. the most well executed scams may not even be recognized by scams at all) and Dash's instamine is particularly subject to that question since it is by its nature deceptive (Bytecoin too).
Again, an assumption yet to be clarified by the OPS (original pot stirrer)
EDIT:
OP's OP in this thread does actually clarify somewhat, but the poll question is still the poll question.
