this mines only sha256 and its a merged mining pool so you mine BTC, NMC, IXC, DVC, you can also trade your ghs on cex.io back to btc or nmc just like trading on btce or cryptsy so if you dont want the ghs anymore you can get bitcoin back for the ghs, also as u get bitcoin and nmc payments you can buy more ghs as you mine and soon you will be able to use cex.io ghs to mine in other sha256 pools, checkout my hash rate below
