Until Evan makes FULL DISCLOSURE of the truth, then he is scammer. There is no other valid sentiment.
Even if disclosure were made now, there have been two years of deception, obfuscation, and spin (not only by Evan but by the other useful idiots like AlexGR who, assuming no more explicit involvement, got in early and allowed themselves to be recruited by their own greed as accomplices). That can't be erased from history any more than MtGox would cease to be a scam if Karpeles showed up and told us the missing coins, that he misled people about for possibly years, was all just a big accident.
Anyone who bought Dash on the basis, in whole or part, of misleading statements from Evan or the others and then lost money has been scammed.Thus a correction is needed:
Evan Duffield, along with AlexGR and the rest of the Dash shills who continue to scam investors (DASH)
