That's what people said about Bitcoin too, of course there were skeptics.
Darkcoin solves what Bitcoin didn't, perfect anonymity.
How is Darkcoin different from Zerocoin, anyway?
a) How do I mine it or purchase it, and
b) how much was premined?
No darkcoin was premined, it can be purchased on exchanges such as Cryptsy and Mintpal.
Zerocoin is centralized, so how "anonymous" it is is basically controlled by the devs and 3rd parties.
Darkcoin can be mined with CPU/GPU, since it's x11 is Highly ASCIS resistant, giving back mining to the general population instead of having companies with millions of dollars dominate it like in Bitcoin and soon to be Litecoin.
Darkcoin was highly undervalued, but which it's release of Darksend(it's finally out of Beta, though not 100%), it's price is going to continue to what it rightfully belongs to be worth.
