Just buy the coins instead fellas. more profitable.
... or if you don't want to buy the coins, don't buy anything at all. Just like ASICs, this 'leased' mining is way overpriced. lol, they wouldn't be selling it if they could make more by using it themselves. I'd be shocked if cryptsy isn't getting its mining power from ghash.io as well. I'm pretty sure they have > 50% of the mining power, they're just doing a good job of disguising it.... re: can't you mine on different pools with cex now?
But as to the actual prices, if Cryptsy doesn't a) shutdown, or b) isn't full of shit about the "lifetime" contract (which I'd say should be at least 3 years), the Cryptsy price is a better deal. After next difficulty increase, CEX maintenance costs are probably going to be near 50%?
The thing is, I wouldn't be surprised if Cryptsy ended that "lifetime" contract as soon (maybe a month or two later, to throw off suspicion) as ghash.io's maintenance costs exceeded profit. Then again, you'd imagine they'd be using more energy efficient equipment by then, so who knows..
