Am I totally miscalculating or will these ASICs never break even? I just used whattomine for the 30S++ at 10 cents and the breakeven is at about 21 years.
Bitcoin mining is no longer profitable on 'normal' / typical home electric rates. Unless you have free power or extremely cheap power, you would never break even. If Bitcoin sees a huge bull-run (significant increase in price) this could change of course but it seems the days of profitable mining at home are over.
A 10 cent a kwatt home miner is doing so for reasons other then profit.
