Bitcoin Mining Profit Guide April 2026: 14 ASIC Rigs Compared at $0.04 Per kWh

Bitcoin mining profitability remains robust as of April 23, 2026: hashrateindex.com logged a hashprice of $36.46 per PH/s, keeping all 14 top-ranked ASIC rigs profitable at an electricity cost of $0.04/kWh. Bitmain’s Antminer S23 Hydro 3U leads with estimated daily earnings of $31.62, while the profitability spread among the top machines runs from $12.73 to $31.62 per day. Thirteen of the 14 leading units require hydro or immersion cooling, underscoring the industry shift toward liquid-cooled, high-density deployments. New and upcoming machines (Bitdeer Sealminer A4 series, MicroBT M79S, several M7D/M7DS models) and improved efficiency are supporting margins, but the article notes profitability is sensitive to changes in electricity rates, network difficulty/growth and bitcoin’s price — any of which could quickly reshuffle the ranking. Overall, miner economics look favorable today, benefiting operators with low-cost power and modern hardware.
