According to the calculator, I should produce a block every 14 days, 2 hours, 3 minutes, or every 338.05 hours. It would cost me 47.327 Kwh to produce a block, at 12 cents per Kwh, thats $5.68 per block, a net loser. <br/><br/>What is interesting is the reports of the people producing 25,000 khash/sec with their video cards in the CUDA thread. If they are using less than 1000 watts (and should be), it would be profitable again to produce, electricity wise.<br/><br/>Difficulty level 1000 by year end.<br/></div><br/>2000 at least imo, but my guess is 8500.</div> text/html
