On April 23, 2026, Bitcoin's hashprice reached $36.46 per petahash per second, enabling all 14 top ASIC miners tracked by asicminervalue.com to generate positive daily returns at an electricity cost of $0.04/kWh. This data, corroborated by hashrateindex.com, highlights a rare alignment of favorable hashprice and efficient hardware even as network difficulty remains elevated.
Top Performers in Daily Profit
Bitmain's Antminer S23 Hydro 3U tops the chart with an estimated $31.62 per day. Launched in January 2026, it delivers 1.16 PH/s at 11,020 watts (9.5 J/TH) and requires three-phase 380-415V power. MicroBT's Whatsminer M79S follows closely at $29.91/day with 1.35 PH/s and 20,000W (14.81 J/TH), designed for liquid cooling. Bitdeer's Sealminer A4 Ultra Hydro, slated for May 2026, ranks third at $24.20/day (886 TH/s, 8,372W, 9.45 J/TH), setting a new efficiency record. The Antminer S23e Hydro 2U ($23.17/day) and S21e XP Hydro 3U ($20.56/day) round out the top five.
Cooling Diversity and Mid-Range Rigs
MicroBT's Whatsminer M79 yields $19.55/day (920 TH/s, 14,500W, 15.76 J/TH), the least efficient in the top half. Notably, Block's Proto Rig is the only air-cooled machine in the top 14, earning $18.28/day (819 TH/s, 12,000W) with hot-swappable hashboards and sub-90-second repair times. Bitdeer's Sealminer A4 Pro Hydro ($17.62/day) and A3 Pro Hydro ($16.09/day) require water immersion. MicroBT's M7DS ($15.91/day) and Bitmain's S23 Hyd ($15.81/day) maintain profitability. Lower-tier models like the M7D ($14.23), S21 XP+ Hydro ($12.91), and M73S+ ($12.73) still operate in positive territory.
Industry Shift and Risk Factors
Of the 14 ASICs, 13 demand water or immersion cooling, reflecting the industry's pivot to high-density, high-wattage rigs. Bitdeer officially launched the Sealminer A4 series on April 7, 2026, with its flagship achieving 9.45 J/TH. However, the current profit window depends on three volatile variables: electricity rates, network hashrate, and Bitcoin's price. A shift in any of these could rapidly reorder the profitability ranking. For now, modern ASIC fleets enjoy a rare period where scale, efficiency, and timing converge — a window miners must hedge carefully.
