BITBAY!! - An altcoins with actual tech behind them rather than hype. Bitbay has just created the first ever working decentralised market and is in the process of getting pegged to the dollar. Bitbays led dev is David Zimbeck - the guy who created 'Halo' and 'Night-trader' for Blackcoin. He's behind Bitbay and works on it full-time! Should easily be on par with Blackcoin in marketcap!
Sounds good, but NXT has already done this for some time, along with other platforms out there.
No they are not true decentralised! Only Bitbay offer this
