With Bitcoin’s price and network difficulty today, as well as the electricity cost set at just $0.02 per kilowatt-hour, some groups on mining rigs are making serious profits. These are the top 50 machines, the best machines for August 2025.
Power, Profit, and Accuracy: Today’s Top 50 BTC Mining Machines
The economics of Bitcoin (BTC) mining can change overnight, but for operators with ultra-low power costs, some machines stand out as clear profit leaders. The following rankings capture the most profitable miners of the weekend from August 9th to 10th, 2025, based on Asicminervalue.com metrics, BTC prices, current network difficulty, and energy rate of $0.02 (KWH) per kilowatt-hour (KWH). This is a rare look at how raw hashrate, power draw and design efficiency combine to turn watts into wealth.
Tier 1 – Elite Class ($40-$30/day)
It towers over everything else Bitmain’s Antminer S21E XP Hydro 3UThe direct liquid-to-chip giant offers 860 terra hash per second and draws $43.56 a day under these conditions. The 11,180 watts appetite is quite large, but efficiency is unparalleled at the top.

Only other miners are dividing the top 20 dollar range –Aurazine’s Teraflux AH3880push 600 Th/s at 8,700 watts for $28.98 daily. The AH3880 does not challenge Bitmain’s flagship with its pure output, but it solidifies Aurazine’s position as a serious player in the Hydro-Cooled High-Performance category.

Tier 2 – Heavy Hitter ($29-$20/day)
Beneath Elite 2 there is a cluster of dense profit machines controlled by Bitmain, Bitdeer, Canaan and Microbt. Bitmain’s Antminer S21 XP+ Hydro Leading this tier, matching the 500th 1 to $25.81 a day, followed by Bitdeer’s Sealminer A2 Pro Hydro The same hashrate costs $24.87 a day. Bitmain also makes fields into fields S21 XP Hydro 473 Th/s and $24.19 a day; S19 XP Hydro 3U It brings you $24.04 with a slightly higher 512 Th/s rating.

Whatsminer M66S ++ It continues for 356 Th/s for $17.60 a day. Bit Main S21 Hydro Deduct 335 Th/s for $16.49 per day S21+Hydro $15.85 per day from 319 Th/s. Whatsminer M63 Match the $15.81 mark with 334 th/s and M66S+converts 318 Th/s to $15.50 per day.
Tier 4 – Consistent earners (per $14-10)
A combination of cooling styles works here. Bitmain’s immersive model leads: S21 XP Immersion 300 Th/s and $15.12 per day; S21 Immersion 301 Th/s and $14.45 a day. Microbt’s M66S Delivers 298 Th/s for $14.31 per day during Bitmain S21E long Press 288 Th/s for $14.03 a day. S19 XP+ HYD It appears twice at 293 Th/s for $14.00 per day and at 279 Th/s for $13.33 per day. Air-cooled S21 XP Adjacent to the side of the Microbt, it produces 270 Th/s for $13.61 per day M66 280 Th/s and $13.26 a day.
Canaan’s Avalon A1566Iimmersive model, outputs 261 TH/s for $12.69 per day, Bitdeer’s SealMiner A2 Pro Air 255 th/s. Bit Main S19 XP HYD (257 Th/s, $12.06 a day) and S21 Pro (234 th/s, $11.63/day) followed by microbt’s flow M53S 260 Th/s for $11.55 a day. Bit Main S21+ (235 Th/s, $11.51/day) sits side by side with Microbt M60S ++ (226 Th/s, $11.13/day) and Bitdeer SealMiner A2 Same hash rate and $11.07 a day.

Canaan’s Avalon A1566 Adding 185th for $8.88 a day and finishing off the top 50 is Bitmain S19 Pro+ HydDelivers 198th at $8.65 per day.
In these layers, Bitmain claims 23 out of the top 50 spots, Microbt holds 15, Canaan has 6, Bitedeer Captures 4, and Auradine have two shocking appearances. Water-cooled rigs dominate the upper layer, but air and immersion models still play a key role for miners optimizing capital and operational strategies. With constant efficiency improvements and new releases on the horizon, current leaders are setting high bars for profitability in the 2025 mining landscape.
