At current Bitcoin price and network difficulty, and with electricity costs set at just $0.02 per kilowatt-hour, a select group of mining rigs pull in serious profits. The following ranking, based on data from asicminervalue.com, captures the most profitable miners between August 9-10, 2025. It offers a rare view into how raw hashrate, power draw, and design efficiency combine to turn watts into wealth.
Tier 1 – Elite Class ($40–$30/day)
Towering over all others is Bitmain’s Antminer S21e XP Hydro 3U, a direct liquid-to-chip behemoth delivering 860 TH/s and pulling in $43.56 a day under these conditions. Its 11,180-watt appetite is substantial, but efficiency keeps it unmatched at the top. Only one other miner cracks the upper-$20s range—Auradine’s Teraflux AH3880, pushing 600 TH/s at 8,700 watts for $28.98 daily.
Tier 2 – Heavy Hitters ($29–$20/day)
Below the elite two is a dense cluster of profit machines dominated by Bitmain, Bitdeer, Canaan, and Microbt. Bitmain’s Antminer S21 XP+ Hydro leads this tier, matching 500 TH/s with $25.81/day, followed closely by Bitdeer’s Sealminer A2 Pro Hydro at $24.87/day. Bitmain also fields the S21 XP Hydro at 473 TH/s ($24.19/day), while the S19 XP Hydro 3U brings in $24.04 with 512 TH/s. Canaan’s Avalon A1566HA 2U delivers 480 TH/s for $23.44/day, and Microbt’s Whatsminer M63S++ produces $22.94 daily with 464 TH/s. Bitmain’s S21e XP Hydro (430 TH/s, $21.78/day) and Microbt’s Whatsminer M63S+ (424 TH/s, $20.66/day) round out the bracket.
Tier 3 – Solid Performers ($19–$15/day)
For operators chasing steady profitability without the power extremes, Tier 3 offers compelling options. Microbt’s Whatsminer M63S produces 390 TH/s for $18.72/day, and Auradine appears again with the Teraflux AI3680 at 375 TH/s and $18.63/day. The Whatsminer M66S++ follows at 356 TH/s ($17.60/day). Bitmain’s S21 Hydro pulls 335 TH/s for $16.49/day, while the S21+ Hydro yields $15.85/day from 319 TH/s. The Whatsminer M63 matches $15.81 with 334 TH/s, just ahead of the M66S+ (318 TH/s, $15.50/day).
Tier 4 – Consistent Earners ($14–$10/day)
Here, a mix of cooling styles comes into play. Bitmain’s immersion models lead with the S21 XP Immersion at 300 TH/s ($15.12/day) and the S21 Immersion at 301 TH/s ($14.45/day). Microbt’s M66S delivers 298 TH/s for $14.31/day, while Bitmain’s S21e Hyd pushes 288 TH/s for $14.03/day. The air-cooled S21 XP produces 270 TH/s for $13.61/day, flanked by Microbt’s M66 at 280 TH/s ($13.26/day). Canaan’s Avalon A1566I outputs 261 TH/s for $12.69/day, matched by Bitdeer’s Sealminer A2 Pro Air at 255 TH/s. Other models include Bitmain’s S19 XP Hyd (257 TH/s, $12.06/day), S21 Pro (234 TH/s, $11.63/day), and Microbt’s M53S (260 TH/s, $11.55/day).
Tier 5 – Foundation Level ($9–$4/day)
While these machines earn less per day, they maintain strong efficiency profiles at $0.02/kWh. Microbt’s M33S++ produces 242 TH/s for $10.28/day, while Canaan’s Avalon A15XP-206T outputs 206 TH/s for $9.96/day. The hydro-cooled M53 from Microbt earns $9.88/day at 230 TH/s, and Bitmain’s S21 clocks 200 TH/s for $9.70/day. Closing out the top 50 is Bitmain’s S19 Pro+ Hyd, delivering 198 TH/s for $8.65/day.
Across these tiers, Bitmain claims 23 of the top 50 spots, Microbt holds 15, Canaan secures 6, Bitdeer captures 4, and Auradine makes 2 high-impact appearances. Hydro-cooled rigs dominate the upper tiers, but air and immersion models still play critical roles for miners optimizing capital and operational strategies. With efficiency gains and new releases always on the horizon, the current leaders set a high bar for profitability in 2025’s mining landscape.
