Bitcoin Mining Profit Guide April 2026: 14 ASIC Rigs Compared at $0.04 Per kWh
Key Takeaways:
Bitmain Antminer S23 Hyd — $15.81/day
Released January 2026, the single-unit S23 Hyd is rated at 580 TH/s with a 5,510-watt draw. Specs indicate an efficiency of 9.5 J/TH, matching the rated figure of the S23 Hyd 3U listed above. Daily profit sits at $15.81 based on current hashprice data.
MicroBT Whatsminer M7D — $14.23/day
Released in March 2026, the base Whatsminer model M7D is listed at 634 TH/s at 9,200 watts with a rated efficiency of around 14.5 J/TH. It sits at $14.23 per day based on the current hashprice and a $0.04 per kWh electricity cost.
Bitmain Antminer S21 XP+ Hydro — $12.91/day
Released last summer in July, the S21 XP+ Hydro is rated at 500 TH/s with a 5,500-watt draw and a listed efficiency of 11 J/TH. Current data places its daily return at $12.91 at $0.04 per kWh.
MicroBT Whatsminer M73S+ — $12.73/day
Released December 2025, the M73S+ is listed at 540 TH/s with a 7,200-watt draw and a rated efficiency of around 13.33 J/TH. It sits at the bottom of the current profitability table but remains positive at $12.73 per day under the $0.04 per kWh electricity rate.
For now, the math works in miners’ favor. Stronger hashprice, efficient hydro-cooled rigs, and low-cost power can keep margins intact even as difficulty holds firm. But this window depends on tight variables, electricity rates, network growth, and of course, bitcoin’s price. If any shift materially, today’s profitability table can be reordered quickly. Until then, modern ASIC fleets are operating in a rare stretch where scale, efficiency, and timing are aligned.
