Lets do a thought experiment: lets say you wanted $10,000 worth of bitcoin, and it costs an equal amount of electricity to mine. At 10c/kWh, thats 100,000kWh of electricity. There are ~720 hours in a month, so you need to be pulling 138kW 24/7 for a month to use up that much electricity. Is that realistic for a typical home? (spoiler: no)
