The cryptocurrency mining landscape has undergone significant shifts in recent years, particularly for SHA-256-based networks like Bitcoin (BTC) and Bitcoin Cash (BCH). After a prolonged bear market that severely impacted miner revenues and forced many operations to shut down, new data suggests a gradual recovery is underway. With gross mining profit margins rising to 39%—a notable increase from recent lows—the industry may be turning a corner. This resurgence is further supported by increasing network hashrate and the adoption of more efficient mining hardware.
Signs of Market Recovery: Rising Gross Mining Profit Margins
The crypto mining sector has long been characterized by intense competition and razor-thin margins. For much of 2018 and early 2019, SHA-256 miners faced mounting losses as digital asset prices plummeted. At their peak in August 2018, the combined hashrate of Bitcoin and Bitcoin Cash hovered around 65 EH/s. By December 2, that figure had dropped to just 32 EH/s, representing a nearly 50% decline from its high.
However, recent trends indicate stabilization and growth. As of March 2025, the combined average hashrate for both networks has rebounded to approximately 45 EH/s, signaling renewed confidence among miners.
According to a detailed report by Diar, while miner revenues have declined significantly—falling to their lowest levels in 19 months—gross profit margins have increased by 39%. In February 2025 alone, despite an overall revenue drop, the improvement in profitability marked a critical turning point.
For context, Bitcoin miner income peaked in December 2017 at roughly $295 million** in fees and block rewards. Today, that combined total stands at about **$195 million, reflecting the broader market correction. Yet even with lower income, reduced operational costs—especially electricity and older equipment depreciation—have helped improve margins.

While current gross margins are far below the 94% recorded at the beginning of 2018, climbing from a low of 32% to 39% suggests improving efficiency and selective consolidation within the mining ecosystem. Smaller, less efficient operations have exited the market, allowing more resilient players to capture greater share and optimize returns.
Over Half of Bitcoin Cash Miners Still Active on Bitcoin’s Blockchain
One of the most intriguing developments in the current mining environment is the continued overlap between Bitcoin and Bitcoin Cash mining operations.
Data from Blockchain.com reveals that around 14 large-scale mining entities dominate the Bitcoin blockchain, with approximately 23% of hashrate attributed to unidentified miners. On the Bitcoin Cash network, about 13 major miners control the chain, with unknown participants accounting for roughly 10% of total activity.
As of March 6, 2025, Bitcoin’s average network hashrate stood at 40.45 EH/s, while Bitcoin Cash operated at a much lower 1.4 EH/s. Despite this disparity, profitability on both chains remains stable, and crucially, six of the largest BCH miners are also top-tier BTC miners.
This dual-network presence underscores a strategic shift: miners are leveraging slight upticks in spot prices and improved margins to maintain operations across both ledgers. The economic incentive to switch between chains based on real-time profitability—known as profit switching—has become more pronounced, reinforcing interconnected hashrate distribution.
The ability to mine profitably on either chain provides flexibility, especially during volatile periods. As margins improve even marginally, miners find it economically viable to keep hardware running rather than powering down during downturns.
Next-Gen Miners Boost ROI and Reignite Mining Activity
A key driver behind the improving profit landscape is the rollout of next-generation mining hardware offering significantly higher efficiency and return on investment (ROI).
Diar’s analysis highlights that despite falling crypto prices—BTC and BCH are still down 80–90% from their all-time highs—miners are once again investing in new equipment. This renewed capital expenditure signals growing optimism.
For example, Bitmain’s flagship Antminer S15, launched at the start of 2025, sold out twice due to strong demand. New units are expected to ship in April 2025. More importantly, the S15 offers an 84% higher ROI compared to its predecessor, the widely used S9 model.
Other competitive models now entering the market include:
- Ebang’s Ebit E11++
- Bitmain’s Antminer S15 (28Th version)
- Innosilicon’s Terminator 43T
- Asicminer’s Nanos 44Th and 8 Nano Pro
These next-gen SHA-256 miners can generate daily profits ranging from $0.25 to $1+ per unit, depending on electricity costs and network difficulty. While these figures may seem modest, they represent a break-even or slightly positive margin for well-optimized mining farms—especially when powered by low-cost renewable energy.
Moreover, used ASICs like the S9 have dropped dramatically in price, making entry more accessible for smaller operators. Combined with improved margins, this creates a feedback loop: higher profits → reinvestment in efficient gear → increased network hashrate → greater security and stability.

Still, long-term sustainability hinges on broader market conditions. Miners universally hope for a sustained price rebound in BTC and BCH, which would dramatically improve cash flow and justify further expansion.
Frequently Asked Questions (FAQ)
Why are mining profit margins rising even as crypto prices remain low?
Improved margins stem from falling operational costs—notably cheaper electricity and reduced depreciation of older hardware—as inefficient miners exit the market. Surviving operations benefit from less competition and better resource allocation.
Are Bitcoin and Bitcoin Cash mined using the same equipment?
Yes. Both BTC and BCH use the SHA-256 proof-of-work algorithm, meaning miners can use identical ASIC hardware (like Antminers) and switch between chains based on real-time profitability.
What does "profit switching" mean in crypto mining?
Profit switching refers to miners dynamically choosing which blockchain to mine based on which offers the highest immediate return. This behavior links BTC and BCH hashrate trends closely.
How do new mining machines improve ROI?
Next-gen ASICs offer higher hash rates with lower power consumption. For instance, the Antminer S15 delivers significantly more processing power per watt than older models like the S9, reducing electricity costs—the largest expense for miners.
Is mining still profitable in 2025?
Yes, but only under certain conditions: access to low-cost power (ideally under $0.06/kWh), efficient cooling systems, and modern hardware. Profitability varies widely by region and setup scale.
Will rising hashrate lead to another price surge?
Not directly. However, increasing hashrate reflects growing miner confidence and network security—both bullish indicators that often precede price appreciation over time.
The revival of mining profitability—even amid subdued market prices—demonstrates the resilience and adaptability of the crypto mining ecosystem. With gross margins climbing to 39%, next-gen hardware rolling out, and strategic cross-chain mining activity on the rise, the foundation for a sustainable recovery appears solid.
