To be honest, just stick with ShadowMarket. Who the fuck cares if the word 'shadow' has a negative connotation? Don't censor yourself. You should be proud of the name ShadowCash / Market. And especially don't Darkcoin / Dash this awesome project by rebranding. If whoever has a problem with this project's name, tell them to stop being whiny cunts and to go fuck themselves.
I wouldn't put it quite so harshly, but I have to agree. The moment they changed Darkcoin to Dash I was no longer interested. Still have a few coins, but could care less what they do. Sort of like a great heavy metal band that starts changing their music so they can pander to a wider audience. It NEVER works! In my opinion SDC should stay true to it's original theme, and let the technology do the talking.
TrumpMarket.
Once Trump hears about it: "Yeah I hear they have this new anonymous market called TrumpMarket. It's so good they named it after me, I like that! It's gonna be YUGE!"
