Comparing SealMiner A2 with Other Top BTC Miners
With the release of the SealMiner A2, Bitdeer has entered the high-performance BTC mining hardware market with serious intent. But how does it stack up against other well-known mining rigs in terms of performance, power efficiency, and overall value? Let’s take a closer look by comparing the A2 with some of the most talked-about SHA-256 miners from major brands.
Key Specifications Comparison
Efficiency: A Critical Factor in 2025
In 2025, power efficiency has become just as important—if not more—than pure hashrate. Rising electricity prices and tighter ROI margins mean that miners are prioritizing performance-per-watt. The SealMiner A2 shines in this regard, delivering a competitive 16.5 J/TH, putting it on par with Bitmain’s flagship Antminer S21+. This efficiency is a key reason many miners are taking a closer look at Bitdeer’s offering.
Hashrate: Not the Highest, But Well-Balanced
While the WhatsMiner M66 leads in raw power with 280 TH/s, it also consumes over 5500 watts, resulting in a lower energy efficiency. The SealMiner A2 finds a sweet spot with 226 TH/s at just 3730 watts, offering a more sustainable long-term mining option without drastically sacrificing performance.
Brand Landscape: Bitdeer’s Rising Influence
- Bitdeer is known for its global cloud mining services and has now stepped into hardware manufacturing. The A2 is an early but confident entry into the competitive miner market.
- Bitmain and MicroBT are industry veterans with deep hardware experience, while Canaan is respected for its Avalon series and long-standing presence.
- What’s notable is that Bitdeer, as a newer entrant, is matching the leaders in efficiency on its first major release, which speaks to its commitment to R&D and miner-centric design.
Real-World Implications for Miners
For those planning new farm setups or upgrading current hardware, the SealMiner A2 provides a cost-effective path to modern efficiency standards without the highest initial investment that usually comes with the top-end MicroBT units. Additionally, the power savings over time can make a significant difference in profitability, especially in markets with higher electricity costs.

Bitdeer SealMiner A2 Profitability
The Bitdeer SealMiner A2 not only delivers competitive hashrate and energy efficiency, but also offers flexibility in coin selection, allowing miners to optimize their daily profits.
Top Performer: DigiByte (DGB)
At the top of the profitability chart is DigiByte (DGB), offering a net income of $10.29/day, the highest among all listed coins. It provides both high revenue and relatively low energy cost (only 28.1% of revenue goes to electricity), making it the most cost-effective choice for SealMiner A2 users.
Other Profitable Options
- eCash (XEC) and Fractal Bitcoin (FB) follow closely behind with $8.27/day and $7.20/day in net income, respectively.
- Even mining Bitcoin (BTC) directly with the A2 still yields a daily net income of $6.88, which remains competitive for traditional BTC-focused operations.
Energy Cost Assumption
All electricity cost calculations are based on a rate of $0.045 per kWh, which reflects competitive industrial rates in many mining regions. With this assumption, SealMiner A2’s power efficiency of 16.5 J/TH places it in the top tier among current-generation BTC miners.
Suitable for Large-Scale Deployments
Thanks to its efficient performance and stable profitability across multiple SHA-256 coins, the SealMiner A2 is an excellent option for building large-scale mining farms. Its balance of high hashrate, low power consumption, and multi-coin profitability ensures a reliable return on investment for both individual miners and institutional operations.
