CoinDesk reported:
Calculating profitability per machine depended on making several broad assumptions. Energy prices are very specific to a mining operation, and can differ based on location but also what the miner can negotiate with the energy provider. But for the sake of calculation, this model, though global, applied the most recently reported average U.S. average electricity rate for this date in July 2023. This calculation did not take into consideration the initial cost to acquire the machine, however.
