BTCD and DRK are the only ones with notable tech. The rest are vapourware.
Maybe you should look into DogecoinDark, it IS really anonymous...
Wow crackfoo you missed the boat and mislead all in one post.
DogecoinDark is a premium coin at a ridiculously cheap price and as Furio stated, truly anonymous using either TOR or I2P.
DogecoinDark has a dedicated dev that works in infosec so he kind of understands the importance of privacy.
Darkcoin or whatever the F it's called now is way overpriced and its' future is questionable.
As for the dev of peercoindark and dogeblackcoin (same person), someone should skin this P.O.S. before he releases any more coins.
