Will the Hammer BC04 pay for its electricity?
Usually not all of it, and nothing is guaranteed. Pointed at a mining pool, it earns small, steady amounts of bitcoin that can offset part of the power bill. How much depends on Bitcoin's price, the network's total hashrate and your electricity rate, and all three change. Pointed at solo mining, it's a lottery ticket for a whole block.
