At an working expense of $0.04 per kilowatt-hour (kWh), the present crop of SHA256 bitcoin miners kinds into a transparent revenue ladder, with high-hashrate hydro items setting the tempo and some environment friendly air and immersion choices maintaining issues attention-grabbing.
The 4-Cent Check: Which Bitcoin Mining Rigs Nonetheless Shine
The king of the hill at this energy value is Bitmain’s Antminer S23 Hydro 3U, rated at 1,160 TH/s with about 11,020 W on the wall, printing roughly $50.06 per day.
It’s the traditional “throw hash at it” method: immense throughput, wise energy for the category, and a day by day take that units our benchmark for every thing that follows. Nonetheless, the S23 Hydro 3U won’t attain consumers till January 2026.
The runner-up is Bitmain’s Antminer S21e XP Hydro 3U at 860 TH/s and 11,180 W, bringing in $34.23/day utilizing as we speak’s BTC costs. Whereas its effectivity trails the S23 Hydro 3U on a pure TH/s-per-watt foundation, it nonetheless delivers a powerful day by day greenback determine; when low cost energy meets a number of hash, physics and math shake arms.
Third place goes to the Proto Rig at 819 TH/s and a stout 12,000 W, good for $31.30/day. It’s the quintessential custom-class brute created by Block: a contact hungrier than the leaders, however the hashrate retains it within the prime tier. If {the electrical} capability is offered, the unit’s greater draw interprets into proportionally greater day by day output.
The Bitdeer Sealminer A3 Professional Hydro takes our fourth slot with 660 TH/s, 8,250 W, and $26.58/day. Its mixture of hydro cooling and measured energy draw makes it a compelling mid-top possibility. Proper behind it, Bitmain’s Antminer S23 Hydro (non-3U) clocks 580 TH/s at simply 5,510 W and nets $25.03/day, a reminder that not each excessive earner wants a four-figure TH/s badge to compete.
Auradine’s Teraflux AH3880 provides selection to the rostrum crowd: 600 TH/s, 10,740 W, and $21.06/day. It delivers constant output at four-cent energy, putting it in keeping with comparable items. The unit highlights how effectivity and wattage draw create slender margins that separate mid-tier machines.
Bitmain’s Antminer S21 XP+ Hydro follows with 500 TH/s at 5,500 W, producing $20.86 per day. Shut behind, Bitdeer’s Sealminer A3 Hydro delivers the identical 500 TH/s however with a better 6,750 W draw, leading to $19.66 per day. The comparability illustrates how an identical hashrates can yield completely different returns as soon as effectivity is factored in.
The Bitmain Antminer S21 XP Hydro at 473 TH/s and 5,676 W follows at $19.28/day. From there, Bitdeer’s Sealminer A2 Professional Hydro reveals 500 TH/s at 7,450 W and $18.99/day—a contact thirstier than the A3 Hydro on the identical hashrate, however nonetheless stable at this OPEX. Bitmain’s Antminer S23 Immersion (442 TH/s, 5,304 W) provides $18.02/day, a pleasant “cool and quiet” possibility the place immersion is the usual.
Mid-pack begins to compress. Canaan’s Avalon A1566HA 2U posts 480 TH/s at 8,064 W for $17.35/day, and MicroBT’s Whatsminer M63S++ matches the day by day determine—464 TH/s, 7,200 W, $17.35/day. One attracts a bit extra energy for barely greater TH/s; the opposite leans on effectivity. Both method, at four-cent energy, they land on the identical day by day greenback.
Bitmain’s Antminer S21e XP Hydro at 430 TH/s and 5,590 W delivers $17.11/day. The older however nonetheless related Antminer S19 XP Hydro 3U logs 512 TH/s and 10,600 W for $16.59/day, proof that legacy hydro containers stay viable when electrical energy is affordable and uptime is disciplined.
Bitdeer’s Sealminer A2 Hydro (446 TH/s, 7,360 W) slots in at $16.25/day. MicroBT’s Whatsminer M63S+ follows—424 TH/s, 7,208 W, $15.25/day—marking the purpose on our ladder the place energy begins to pinch. Nonetheless, at $0.04/kWh, even these items preserve respectable day by day returns when run repeatedly.
From right here, the sphere turns right into a clinic on effectivity trade-offs. Bitmain’s Antminer S21+ Hydro at 358 TH/s and 5,370 W yields $13.56/day; MicroBT’s Whatsminer M63S lists 390 TH/s, 7,215 W, $13.46/day; and MicroBT’s Whatsminer M66S++ at 356 TH/s and a notably decrease 5,518 W lands $13.31/day. The sample is obvious: trim watts, defend revenue.
Bitmain’s Antminer S23 (air-cooled) posts 318 TH/s at simply 3,498 W for $13.27/day—a reminder that wise wattage can hold smaller-hash rigs within the dialog. Bitmain’s Antminer S21 Hydro at 335 TH/s and 5,360 W yields $12.37 per day, putting it among the many mid-tier machines the place effectivity and hashrate stability towards electrical energy prices
Auradine’s Teraflux AI368Q clocks 360 TH/s, 6,840 W, and $12.25/day. Bitmain’s Antminer S21+ Hydro (the 319 TH/s variant) trims to 4,785 W and nets $12.08/day. These items present constant energy use and output, with efficiency figures that stay secure compared throughout bigger operational teams.
The Antminer S21 XP Immersion at 300 TH/s and 4,050 W returns $11.80/day, whereas Bitdeer’s Sealminer A3 Professional Air rounds out our listing at 290 TH/s, 3,625 W, and $11.68/day. Air nonetheless has a spot—particularly the place water and immersion are impractical—however at this OPEX, hydro and immersion are likely to hold a small edge.
Bitmain’s Antminer S9 collection, as soon as the spine of worldwide hashpower earlier than 2019, now operates at a loss—even with electrical energy priced at $0.04 per kilowatt-hour. Models just like the S9 SE, S9i, S9j, and the S9 Hydro all generate unfavourable returns, with day by day losses from $0.39 to $0.72. As soon as the trade’s defining workhorse, the S9 household as we speak serves extra as a relic of bitcoin mining’s previous than a viable possibility.
What jumps out throughout all 26 fashions (not together with the S9s) is how the hydro-cooled class has seized the higher rungs. The very prime is a hashrate story—the S23 Hydro 3U’s 1,160 TH/s can bulldoze variance when it drops in January—however the mid-table is an effectivity story, the place sub-7 kW rigs with 300–500 TH/s dangle surprisingly shut on day by day {dollars}. Low cost energy lets sheer hash win; sensible energy budgets hold the environment friendly items within the cash.
One other takeaway: parity moments are actual. The Canaan Avalon A1566HA 2U and MicroBT Whatsminer M63S++ each printing $17.35/day present how completely different design selections can converge at a given electrical energy value. For operators, meaning procurement can consider availability, guarantee, and fleet standardization with out giving up revenue—helpful in a market the place provide timing is half the sport.
Mixing distributors additionally hedges threat. A lineup that spans Bitmain’s S23/S21 households, Bitdeer’s Sealminer A-series, MicroBT’s M63/M66 items, Auradine’s Teraflux fashions, a Canaan Avalon anchor, and even a custom-style Proto Rig from Block helps a farm navigate elements, firmware, and logistics throughout cycles. At $0.04/kWh, the mathematics helps range with out sacrificing a lot on the meter.
In brief, at a four-cent OPEX threshold, the revenue ladder is topped by high-throughput hydro gear—the upcoming Bitmain Antminer S23 Hydro 3U—with a tightly packed midfield the place effectivity retains the lights simply as inexperienced. From the S21e XP Hydro 3U and Proto Rig right down to the Sealminer A3 Professional Air, each mannequin right here can pull its weight; the best alternative on your rack depends upon amps, aisle, and urge for food.
