OK, it depend on what do you mean under 'profitable', since with this difficulty the ROI for Jalapeno is 12+ months (without electricity costs) and this applies only in case if difficulty stays at this level and will not increase.. 12 months is too much, have you any idea how fast and energy efficient ASICs will be on market at the end of 2013? after 6 months on the market Japalenos will be good only as a paperweight
