With bitcoin climbing 14.6% over the past 30 days, miners are raking in higher earnings. The going rate for 1 petahash per second (PH/s) of hashpower now floats around $60.49, padding profits for some of the top application-specific integrated circuit (ASIC) rigs available. Here’s a look at the leading machines of the moment and how they’re stacking up in 2025’s ongoing BTC bull run.
Bitcoin’s Bull Run Powers Mining Profits
Bitcoin mining rigs are generating noticeably more value than they were just a month ago. Back then, the spot price for 1 petahash per second (PH/s) was $53.20—today, it’s clocking in at $60.49, marking a 13.7% jump in just 30 days. At an operating expense (OPEX) of $0.06 per kilowatt hour (kWh) and given today’s difficulty levels, the reigning king of ASIC miners is Bitmain’s Antminer S21e XP Hydro 3U, cranking out an impressive 860 terahash per second (TH/s).
However, the machine guzzles a hefty 11,180 watts (W) of power to keep that hashpower humming. For context, most residential air conditioners draw about 2,000 to 3,000 watts, so this single mining rig pulls the same power as three to five AC units running nonstop. With that in mind, at current rates, the S21e XP Hydro 3U is pulling in an estimated $35.66 in daily profit. Coming in second is the Teraflux AH3880 by Auradine, which delivers 600 terahash per second (TH/s) of hashpower.
The American-made Teraflux AH3880 draws about 8,700 W, making it slightly more energy-efficient than the top contender, though it lags behind in raw hashing power. Trailing just behind the Teraflux AH3880 is Bitmain’s Antminer S21 XP+ Hydro, a 500 TH/s workhorse that sips a modest 5,500 W. The model currently clocks about $22.17 in daily profit and has an energy efficiency rating of 11 joules per terahash.
Bitmain’s Antminer S21 XP Hydro.
Close 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 slightly lower hashrate can still punch above its weight. Bitdeer’s Sealminer A2 Pro Hydro, fresh off its March 2025 debut, pumps out 500 TH/s at 7,450 watts, generating around $19.36 daily. Then there’s Bitmain’s S21e XP Hyd from November 2024, with a 430 TH/s output and 5,590 W power draw—enough to pocket an estimated $17.83 per day.
Meanwhile, Canaan’s Avalon A1566HA 2U offers a hefty 480 TH/s at 8,064 watts, earning $17.27 every 24 hours. Bitdeer makes another appearance with its February 2025 Sealminer A2 Hydro, delivering 446 TH/s at 7,360 watts, good for an estimated $16.24 in daily income. Bitmain’s older but still capable S19 XP Hydro 3U throws down 512 TH/s, chugging 10,600 watts to pull in $15.55 a day. MicroBT’s Whatsminer M63S+ puts up 424 TH/s at 7,208 W, collecting $15.14 in profit. And last but not least, the Auradine Teraflux AI3680 rounds things out with 375 TH/s, a 5,625-watt appetite, and a respectable $14.47 daily return.
Tiny Rigs, Big Dreams: Micro-Miners Still Earning
For hobbyists and low-power tinkerers, the numbers shrink—but the fun doesn’t stop. Bitmain’s older Antminer S17+ from 2019 squeezes out $0.19 per day at 73 TH/s with 2,920 watts. Right behind it is the bite-sized Nerdminer NerdQaxe++, a newer tiny rig launched in March 2025 that sips just 76 watts for 4.8 TH/s—and still nets $0.18 a day.
The mini-miner Bitaxe Supra Hex 701.
Two iterations of the Bitmain S17 Pro from April 2019—one with 53 TH/s and the other with 50 TH/s—both hover around $0.16 to $0.17 per day, still hanging on despite their age. Meanwhile, the compact Canaan Avalon Nano 3S delivers 6 TH/s at just 140 watts, also clearing $0.16 daily. Rounding out the micro-miner league is the Bitaxe Supra Hex 701, a sleek June 2025 launch with 4.2 TH/s and 75 watts of draw—modest specs that still bring in an estimated $0.14 a day in profits.
The S9 Saga: From Money Pit to Modest Comeback
Of course, not all miners are riding high. The once-legendary Bitmain Antminer S9 series, a former titan of the bitcoin mining world, is now in the red at $0.06 per kWh. The S9 SE, launched in June 2019 with 16 TH/s at 1,280 watts, is currently losing around $0.88 per day. The original S9 model from 2017—offering just 11.5 TH/s at 1,127 watts—is bleeding about $0.93 daily. And it only gets worse from there.
At one point in time, Bitmain’s S9 units powered a great deal of Bitcoin’s hashrate.
The S9 with 12.5 TH/s and the S9i at 14 TH/s are now underwater by $1.01 and $1.06 per day, respectively. Meanwhile, the S9j and S9k models, both hovering around 13.5 to 14.5 TH/s and gulping 1,300+ watts, are each leaking $1.07 daily. These aging workhorses had their moment in the spotlight, but 2025’s difficulty levels and electricity costs have turned them into power-hungry relics.
But give these old-timers cheap power, and they’ve still got some fight left in them. At just $0.02 per kWh, the Bitmain Antminer S9 SE from Jun 2019 pulls in a daily profit of $0.35 with its 16 TH/s and 1,280-watt appetite. The S9 Hydro, a 2018 model built to handle higher wattage and 18 TH/s, nets $0.25 a day—even while guzzling 1,728 watts.
Other S9 models also claw their way back into the black. The S9j and S9i, both from 2018 with roughly 14 TH/s and similar power draws around 1,300 watts, are currently earning $0.22 and $0.21 daily, respectively. Even the OG S9 from 2017 and its slightly newer sibling, the S9k, bring in $0.18 per day apiece when sipping electrical power at bargain rates.
So while most S9s are buried under standard electricity prices, dropping the OPEX flips the script. Under the right conditions, these aging rigs can still mine their way to a few bucks a week—and stay alive just a little longer in the fast-evolving world of bitcoin mining.
