Bitcoin News Today: Bitmain's S21e XP Hydro Dominates Bitcoin Mining Earnings With $43.56 Daily Profit

Bitcoin mining profitability in mid-August 2025 is being dominated by a narrow group of high-efficiency machines, as operators with ultra-low electricity costs—set at $0.02 per kilowatt-hour—capitalize on favorable conditions to maximize returns [1]. A comprehensive ranking of the top 50 most profitable mining rigs was compiled using metrics from asicminervalue.com, current BTC prices, network difficulty, and energy costs, offering a detailed look into how raw hashrate, power consumption, and design efficiency combine to generate daily profits [1].

At the top of the list is Bitmain’s Antminer S21e XP Hydro 3U, a direct liquid-to-chip miner capable of delivering 860 terahashes per second (TH/s) and generating $43.56 in daily earnings [1]. Despite its 11,180-watt power draw, the Antminer remains unmatched due to its superior efficiency. Auradine’s Teraflux AH3880 follows closely in second place, pushing 600 TH/s at 8,700 watts and earning $28.98 per day [1]. The AH3880, while not matching the output of Bitmain’s flagship, reinforces Auradine’s growing reputation in high-performance hydro-cooled mining.

The second tier is dominated by Bitmain, Bitdeer, Canaan, and Microbt. Bitmain’s Antminer S21 XP+ Hydro leads this group with 500 TH/s and $25.81 in daily profits, closely followed by Bitdeer’s Sealminer A2 Pro Hydro at $24.87/day [1]. Bitmain’s S21 XP Hydro, S19 XP Hydro 3U, and S21e XP Hydro also perform strongly in this bracket, with daily earnings ranging from $24.04 to $21.78. Canaan’s Avalon A1566HA 2U and Microbt’s Whatsminer M63S++ contribute to the tier with earnings in the $22–$23/day range [1].

Tier 3 consists of reliable but less power-intensive machines, including Microbt’s Whatsminer M63S and Auradine’s Teraflux AI3680, which generate daily profits between $15 and $18 [1]. Bitmain’s S21 Hydro and S21+ Hydro, as well as Microbt’s M63 and M66S+, remain solid performers in this category. These machines are often preferred by miners seeking stable returns without the high energy demands of top-tier models.

Tier 4, the consistent earners, spans a broader range of cooling methods and hashrates, with daily profits between $10 and $14. Bitmain’s S21 XP Immersion and S21 Immersion, as well as Microbt’s M66S and M63S+, represent the diversity of cooling technologies in this bracket [1]. Air-cooled and immersion-cooled models are used strategically depending on capital and operational constraints.

Finally, Tier 5 includes machines earning between $4 and $9 per day, with notable performers like Microbt’s M33S++ and Canaan’s Avalon A15XP-206T maintaining strong efficiency profiles [1]. Bitmain’s S19 Pro+ Hyd closes the top 50 with 198 TH/s and $8.65 in daily earnings.

Across all tiers, Bitmain leads with 23 top-50 placements, followed by Microbt with 15 and Canaan with 6. Hydro-cooled models dominate the upper tiers, but air- and immersion-cooled units remain essential for miners optimizing cost and performance. As new hardware and efficiency improvements continue to emerge, the current leaders set a high standard for profitability in the 2025 mining landscape [1].
