LOL bet half your euthereum it will and if you win you break even almost. And if you lose well that's good news! I have not tried this website are they trustworthy?

Edit: My miner is working great! Using catalyst 14.6 and the older ethereum miner. I actually am managing 50-55mhs per 7990 now. Non stop for 72 hours. That's 2.50$ per day per card. Or 12.5$ per unit. At about 1.3KWH@0,06c/KWh. Which equates to 300$ a month per unit taking power into consideration. Not bad IMHO 2600$ per unit per year or if we take an average difficulty and price and power into consideration that is still about 8 BTC/year. Compared to a 750 ti unit using half the power makes 2BTC/year. Also I am loving the interface!!! Keep it up devs don't listen to the forums listen to the global hashrate!
