So here is my dilemma... I have a 25% off coupon for any purchase amount at Butterfly Labs this month. I was thinking about spending $1,000 to buy 5 more Jalapeños. Would that be a wise move? My 8570 now only breaks even with electricity cost. I'm guessing it may take 4-6 months for the new Jalapenos to arrive. In 6 more months could the Jalapenos already be almost obsolete? Right now they make about $400 a month (1 coin per week.) I don't know how often the payout is reduced and the difficulty increased to make an intelligent decision. Would I be better off to buy some other type of mining gear with the money?
