People are killed because they lack privacy.
Unlike Darkcoin (main competition?) Stealthcoin wasn't originally a scam coin that the creator decided he could continue developing for to make more money. And while Darkcoin had the centralized anonymity nodes (need you to buy 1000 DRK), Stealthcoin's anonymous tech is decentralized and doesn't need you to pump the price to use.
Why are you comparing a shitcoin with Darkcoin... or even Monero and XC ? Show me a line of code from this garbage and not just WhiteToiletPapers.pdf and preannouncements of announcements.
Edit : The fake accounts hyping the shit out of this coin caught my attention big time. It was like a cheerleading contest...
