wow, thank you for doing the math. I guess I haven't been keeping up with bitcoin vs electricity cost. I was going to buy a bitcoin miner when bitcoin was ~$500 and in short order the electricity cost of running the miner exceeded the cost of bitcoin and started getting worse. Now with bitcoin value > 1000x ... hmmm. maybe my assumptions are plain wrong.
