On April 23, 2026, Bitcoin’s hashprice reached $36.46 per petahash per second, enabling operators using the 14 most advanced ASIC miners to achieve positive daily returns with electricity costs at $0.04 per kWh. According to data from asicminervalue.com, net daily profits range from $12.73 to $31.62 across the top-performing rigs.
Top Three Rigs: Efficiency and Profitability Peaks
The Bitmain Antminer S23 Hydro 3U claims the top spot with $31.62 daily profit. Released in January 2026, it delivers 1.16 PH/s at 11,020W, achieving an efficiency of 9.5 J/TH. The machine requires a water-cooled infrastructure and 380–415V three-phase power.
Second place goes to the MicroBT Whatsminer M79S, earning $29.91 per day. Launched in December 2025, it offers 1.35 PH/s at 20,000W with an efficiency of 14.81 J/TH. It is designed for operation with dedicated liquid cooling loops.
The Bitdeer Sealminer A4 Ultra Hydro, scheduled for May 2026 release, achieves a record low efficiency of 9.45 J/TH. It produces 886 TH/s at 8,372W, with projected daily earnings of $24.20. This model underscores Bitdeer’s push toward extreme cooling efficiency.
Broader Market: Multiple Profitable Options
Rigs ranked fourth through tenth generate between $15 and $24 per day. Notable entries include the Bitmain Antminer S23e Hydro 2U ($23.17), Bitmain Antminer S21e XP Hydro 3U ($20.56), MicroBT Whatsminer M79 ($19.55), and Block Proto Rig ($18.28). The Proto Rig is the only air-cooled machine in the top 14, though it is also immersion-ready.
Lower-ranked rigs (positions 11–14) still deliver solid returns: MicroBT Whatsminer M7DS ($15.91), Bitmain Antminer S23 Hyd ($15.81), MicroBT Whatsminer M7D ($14.23), and others. All maintain profitability at $0.04/kWh.
Industry Insight: Water Cooling Dominates, Efficiency Race Accelerates
As of April 2026, 13 of the top 14 ASIC miners require water or immersion cooling. Only Block’s Proto Rig supports air cooling. Bitdeer’s Sealminer A4 series (9.45 J/TH), introduced on April 7, marks a new efficiency standard. Analysts note that the current confluence of elevated hashprice, low electricity costs, and cutting-edge hardware creates a rare profitable environment for miners. However, changes in Bitcoin’s price, network difficulty, or energy costs could quickly reshape the profitability landscape.
