With bitcoin climbing 14.6% over the previous 30 days, miners are raking in greater earnings. The going fee for 1 petahash per second (PH/s) of hashpower now floats round $60.49, padding earnings for among the prime application-specific built-in circuit (ASIC) rigs accessible. Right here’s a take a look at the main machines of the second and the way they’re stacking up in 2025’s ongoing BTC bull run.
Bitcoin’s Bull Run Powers Mining Earnings
Bitcoin mining rigs are producing noticeably extra worth than they had been only a month in the past. Again then, the spot value for 1 petahash per second (PH/s) was $53.20—at this time, it’s clocking in at $60.49, marking a 13.7% bounce in simply 30 days. At an working expense (OPEX) of $0.06 per kilowatt hour (kWh) and given at this time’s issue ranges, the reigning king of ASIC miners is Bitmain’s Antminer S21e XP Hydro 3U, cranking out a formidable 860 terahash per second (TH/s).
Nonetheless, the machine guzzles a hefty 11,180 watts (W) of energy to maintain that hashpower buzzing. For context, most residential air conditioners draw about 2,000 to three,000 watts, so this single mining rig pulls the identical energy as three to 5 AC items operating nonstop. With that in thoughts, at present charges, the S21e XP Hydro 3U is pulling in an estimated $35.66 in each day revenue. Coming in second is the Teraflux AH3880 by Auradine, which delivers 600 terahash per second (TH/s) of hashpower.
The American-made Teraflux AH3880 attracts about 8,700 W, making it barely extra energy-efficient than the highest contender, although it lags behind in uncooked hashing energy. Trailing simply behind the Teraflux AH3880 is Bitmain’s Antminer S21 XP+ Hydro, a 500 TH/s workhorse that sips a modest 5,500 W. The mannequin presently clocks about $22.17 in each day revenue and has an vitality effectivity score of 11 joules per terahash.
Bitmain’s Antminer S21 XP Hydro.
Shut on its heels is the 473 TH/s Antminer S21 XP Hydro, pulling 5,676 watts and bringing in $20.29 a day—proof {that a} barely decrease hashrate can nonetheless punch above its weight. Bitdeer’s Sealminer A2 Professional Hydro, contemporary off its March 2025 debut, pumps out 500 TH/s at 7,450 watts, producing round $19.36 each day. Then there’s Bitmain’s S21e XP Hyd from November 2024, with a 430 TH/s output and 5,590 W energy draw—sufficient to pocket an estimated $17.83 per day.
In the meantime, Canaan’s Avalon A1566HA 2U provides a hefty 480 TH/s at 8,064 watts, incomes $17.27 each 24 hours. Bitdeer makes one other look with its February 2025 Sealminer A2 Hydro, delivering 446 TH/s at 7,360 watts, good for an estimated $16.24 in each day revenue. Bitmain’s older however nonetheless succesful S19 XP Hydro 3U throws down 512 TH/s, chugging 10,600 watts to tug in $15.55 a day. MicroBT’s Whatsminer M63S+ places up 424 TH/s at 7,208 W, accumulating $15.14 in revenue. And final however not least, the Auradine Teraflux AI3680 rounds issues out with 375 TH/s, a 5,625-watt urge for food, and a good $14.47 each day return.
Tiny Rigs, Huge Goals: Micro-Miners Nonetheless Incomes
For hobbyists and low-power tinkerers, the numbers shrink—however the enjoyable doesn’t cease. Bitmain’s older Antminer S17+ from 2019 squeezes out $0.19 per day at 73 TH/s with 2,920 watts. Proper behind it’s the bite-sized Nerdminer NerdQaxe++, a more recent tiny rig launched in March 2025 that sips simply 76 watts for 4.8 TH/s—and nonetheless nets $0.18 a day.
The mini-miner Bitaxe Supra Hex 701.
Two iterations of the Bitmain S17 Professional from April 2019—one with 53 TH/s and the opposite with 50 TH/s—each hover round $0.16 to $0.17 per day, nonetheless hanging on regardless of their age. In the meantime, the compact Canaan Avalon Nano 3S delivers 6 TH/s at simply 140 watts, additionally clearing $0.16 each day. Rounding out the micro-miner league is the Bitaxe Supra Hex 701, a modern June 2025 launch with 4.2 TH/s and 75 watts of draw—modest specs that also usher in an estimated $0.14 a day in earnings.
The S9 Saga: From Cash Pit to Modest Comeback
In fact, not all miners are using excessive. The once-legendary Bitmain Antminer S9 collection, a former titan of the bitcoin mining world, is now within the crimson at $0.06 per kWh. The S9 SE, launched in June 2019 with 16 TH/s at 1,280 watts, is presently dropping round $0.88 per day. The unique S9 mannequin from 2017—providing simply 11.5 TH/s at 1,127 watts—is bleeding about $0.93 each day. And it solely will get worse from there.
At one time limit, Bitmain’s S9 items powered a substantial amount of Bitcoin’s hashrate.
The S9 with 12.5 TH/s and the S9i at 14 TH/s at the moment are underwater by $1.01 and $1.06 per day, respectively. In the meantime, the S9j and S9k fashions, each hovering round 13.5 to 14.5 TH/s and gulping 1,300+ watts, are every leaking $1.07 each day. These getting older workhorses had their second within the highlight, however 2025’s issue ranges and electrical energy prices have turned them into power-hungry relics.
However give these old-timers low cost energy, they usually’ve nonetheless bought some battle left in them. At simply $0.02 per kWh, the Bitmain Antminer S9 SE from Jun 2019 pulls in a each day revenue of $0.35 with its 16 TH/s and 1,280-watt urge for food. The S9 Hydro, a 2018 mannequin constructed to deal with greater wattage and 18 TH/s, nets $0.25 a day—even whereas guzzling 1,728 watts.
Different S9 fashions additionally claw their method again into the black. The S9j and S9i, each from 2018 with roughly 14 TH/s and related energy attracts round 1,300 watts, are presently incomes $0.22 and $0.21 each day, respectively. Even the OG S9 from 2017 and its barely newer sibling, the S9k, usher in $0.18 per day apiece when sipping electrical energy at cut price charges.
So whereas most S9s are buried below customary electrical energy costs, dropping the OPEX flips the script. Below the best circumstances, these getting older rigs can nonetheless mine their method to some bucks every week—and keep alive just a bit longer within the fast-evolving world of bitcoin mining.
