I voted for Goldcoin. I think it's the one to watch in 2014.
X10Goldcoin (GLD) is the one to watch this year. Many of the altcoins have taken a beating, but this one has been excessively hammered. When the bitcoin/altcoin recovery comes, I think this is the currency that's going to rocket.
I would put my money on Particle Coin. Seems like GoldCoin doesn't have that much innovation behind it and really is just another alt coin. The only benefit that i see with Gold Coin is the fact that it wasn't premined.
We need alt coins WITH CHANGES, not clones and mimics of successful coins.
