I'm well into cexio because of their mergemining, cloudmining, and the way you can put spare mined coins into more mining speed, or trade them on the hi/low candles by hand or by tradebot for more profit.
And hey YariDjem sounds like it wouldn't hurt for you to hit cexio too, it's a shame to have the hashpower of a KnC and be missing out on the extra NMC, DVC and IXC you could be getting with 4-coin merge-mining (at no loss to your BTC mining rate)
