Just slightly at current prices. Not tommorows ;-)
Personaly, i would recommend to scroll down to the VTC mining rigs at
http://leaserig.net and find
getluckyBTC miner. It's mine rig now to rent.
Price is bigger than profit.
I dont understand these rental rigs, surely if there was money to be made out of renting one the owner would mine with it? or am i missing something?
