Bitcoin Cash (BCH) remains one of the most prominent cryptocurrencies derived from a hard fork of Bitcoin, offering faster transactions and lower fees thanks to its larger block size. As a SHA-256 algorithm-based digital asset, BCH is mineable using the same generation of ASIC mining hardware designed for Bitcoin. This makes it accessible and profitable for miners who understand the efficiency metrics that drive returns in competitive mining environments.
Whether you're expanding your mining operation or exploring alternative uses for existing Bitcoin mining rigs, this guide dives into the top-performing Bitcoin Cash mining machines, their technical specifications, and how to evaluate profitability based on power efficiency and hashrate performance.
What Is Bitcoin Cash (BCH)?
Bitcoin Cash was created on August 1, 2017, as a result of a hard fork from the original Bitcoin blockchain at block height 478,558. The primary motivation behind the split was to address Bitcoin’s growing transaction congestion and high fees by increasing the block size limit.
While Bitcoin retained a 1MB block size (later expanded via SegWit), Bitcoin Cash adopted an 8MB block size at launch — later upgraded to support up to 32MB blocks. This allows BCH to process more transactions per second, making it better suited for everyday payments and microtransactions.
Despite sharing core features with Bitcoin — including the SHA-256 hashing algorithm, similar emission schedule, and 21 million coin cap — Bitcoin Cash positions itself as "peer-to-peer electronic cash" rather than just a store of value.

Why Mine Bitcoin Cash?
Mining Bitcoin Cash can be a strategic move for several reasons:
- Lower Network Difficulty: Compared to Bitcoin, BCH has significantly lower network difficulty, meaning miners may achieve higher relative rewards with the same hardware.
- Dual Mining Potential: Some pools allow merged mining (or auxiliary proof-of-work), where miners can simultaneously secure both Bitcoin and Bitcoin Cash networks without extra energy costs.
- Cost-Effective Use of Older Hardware: As newer ASICs dominate Bitcoin mining, older models like the Antminer S9 series can still find profitability when directed toward less competitive chains like BCH.
Compatible Mining Algorithms and Hardware Requirements
Since Bitcoin Cash uses the SHA-256 algorithm, any ASIC miner built for SHA-256 is compatible. This includes popular models from manufacturers such as Bitmain (Antminer), MicroBT (Whatsminer), Innosilicon (T series), AvalonMiner, and Ebang (Ebit).
The key factors determining mining efficiency are:
- Hashrate (TH/s): Higher hashrate increases chances of solving blocks.
- Power Consumption (Watts): Lower power draw reduces electricity costs.
- Efficiency (Joules per Terahash, W/T): The lower the number, the more energy-efficient the device.
Miners should prioritize machines with low watt-per-terahash ratios to maximize profitability, especially in regions with higher electricity rates.
Top Bitcoin Cash Mining Machines in 2025
Below is a curated list of the most effective ASIC miners currently used for Bitcoin Cash mining, ranked by performance and efficiency.
High-Performance Miners (50+ TH/s)
These represent the latest generation of efficient mining hardware ideal for large-scale operations.
- Whatsminer M20S – 68 TH/s, 3,385W, 50 W/T
One of the most powerful and efficient options available today. - Antminer S17 Pro – 56 TH/s, 2,780W, 50 W/T
Reliable and widely supported across mining pools. - Innosilicon T3+ (57T) – 57 TH/s, 3,300W, 58 W/T
Strong performance but slightly less efficient than top-tier competitors. - Whatsminer M21S – 56 TH/s, 3,360W, 60 W/T
Slightly less efficient than M20S but still competitive.
Mid-Tier Miners (40–50 TH/s)
Balanced options for moderate setups seeking solid returns without extreme power demands.
- Antminer S17 – 53 TH/s, 2,280W, 43 W/T
Excellent efficiency for sustained profitability. - Ebang E12+ – 50 TH/s, 2,500W, 50 W/T
Known for durability and consistent output. - AvalonMiner A1066 – 50 TH/s, 3,250W, 65 W/T
Older model but still functional in cooler climates.
Entry-Level & Legacy Models (Below 40 TH/s)
Suitable for hobbyists or small miners using surplus equipment.
- Antminer T17 – 40 TH/s, 2,200W, 55 W/T
Great balance between cost and efficiency. - Innosilicon T3 (43T) – 43 TH/s, 2,100W, 49 W/T
Solid performer among mid-range options. - Antminer S9 Series – ~14 TH/s, ~1,400W, ~100 W/T
Once dominant, now best suited only for low-cost electricity environments.
⚠️ Note: Older models like the Antminer S7 or Avalon A7xx series have very high power inefficiency (over 170 W/T). They are generally unprofitable unless electricity is nearly free.

How to Choose the Right BCH Miner
Selecting the right machine depends on multiple factors beyond raw specs:
1. Electricity Cost
If your electricity exceeds $0.10/kWh, focus on sub-50 W/T machines. At $0.06/kWh or below, even older S9s might break even under merged mining setups.
2. Noise and Cooling
High-power ASICs generate significant heat and noise. Ensure proper ventilation or consider remote hosting facilities.
3. Availability and Pricing
Newer models often sell out quickly. Consider refurbished units from trusted resellers if direct supply is limited.
4. Mining Pool Compatibility
Ensure your chosen miner works seamlessly with major BCH mining pools like Binance Pool, Slush Pool, or ViaBTC.
Frequently Asked Questions (FAQ)
Q: Can I use my Bitcoin miner to mine Bitcoin Cash?
Yes. Since both BTC and BCH use the SHA-256 algorithm, any Bitcoin-compatible ASIC miner can mine BCH directly or through merged mining pools.
Q: Is Bitcoin Cash mining still profitable in 2025?
Yes — especially with efficient hardware and low electricity costs. Profitability also improves with merged mining support.
Q: Do I need a separate wallet for mined BCH?
Yes. You must configure your miner to point to a valid Bitcoin Cash wallet address. Using a BTC address will result in lost funds due to incompatible formats.
Q: What is merged mining?
Merged mining allows miners to simultaneously secure multiple blockchains (e.g., BTC + BCH) using the same computational power. No additional energy is required.
Q: How often are BCH blocks mined?
Bitcoin Cash targets a new block every 10 minutes, matching Bitcoin’s average block time.
Q: Are older Antminer S9s worth using for BCH?
Only under specific conditions: very low electricity cost (<$0.05/kWh), access to free cooling, or participation in merged mining setups where secondary rewards boost income.
Final Thoughts on BCH Mining in 2025
Bitcoin Cash continues to offer viable opportunities for miners willing to leverage efficient SHA-256 hardware. With lower network difficulty than Bitcoin and ongoing support for merged mining, it remains a smart alternative for optimizing underutilized rigs.
As competition intensifies on the Bitcoin network, shifting focus to parallel chains like BCH can extend the lifecycle of existing equipment while generating meaningful returns.
