Title: Is USB Erupter ever profitable? Post by: mintedstone on September 01, 2013, 06:27:41 AM The price of USB Erupter going down very quickly, and yet at 0.3-0.4 BTC each, shall we ever get the investment back? At the current diff, each USB Erupter can mine about 2.5X10^-4 BTC per day, which means it can get 0.4 BTC in 160 days (or 5+ months). But with BTC diff rapidly going up, I suspect that the investment can never be recovered. Is my computation correct?
