The Bitcoin mining landscape is undergoing a pivotal transformation, shaped by rising production costs, evolving energy strategies, and increasing pressure to diversify revenue streams. As the network approaches its next halving event and market conditions tighten, mining companies must optimize operations, manage capital efficiently, and adapt to long-term economic realities. This analysis unpacks the latest findings from CoinShares’ Q3 mining report, offering actionable insights into cost structures, profitability models, and strategic shifts defining the future of Bitcoin mining.
Rising Production Costs and Operational Challenges
Bitcoin mining profitability has faced headwinds in 2025 due to declining revenues and lower hash prices. Despite these challenges, major mining firms continue expanding infrastructure, betting on future price appreciation. This expansion has pushed network difficulty to record highs, intensifying cost pressures across the sector.
According to CoinShares' estimates, the average cash cost to produce one Bitcoin among publicly listed miners rose to $49,500** in Q2 2025, up from $47,200 in Q1. While this remains below current market prices—allowing most operators to remain cash-flow positive—the full cost picture is more complex. When accounting for depreciation and stock-based compensation, the all-in cost jumps to $96,100 per Bitcoin**, highlighting the financial strain many companies face.
Access to affordable credit has also tightened since the FTX collapse and broader crypto market turmoil. With rising interest rates and stricter lending terms, miners have increasingly turned to equity financing—often diluting shareholder value. This trend has dampened investor sentiment, especially as mining stocks failed to fully benefit from the surge driven by U.S. spot Bitcoin ETF approvals earlier in the year.
Modeling Hash Rate Growth and Energy Constraints
Accurately forecasting Bitcoin’s hash rate growth is critical for assessing long-term mining economics. Traditional mathematical models—such as exponential or power functions—fall short due to real-world physical and energy limitations. CoinShares’ updated model introduces a segmented approach: an initial phase of rapid exponential growth followed by a slowdown as the network approaches its theoretical energy ceiling.
This ceiling is based on globally stranded natural gas resources—estimated at 150 billion cubic meters flared annually—which can be repurposed for mining. If fully utilized, this would not only power vast mining operations but also reduce carbon emissions by an estimated 63% by eliminating wasteful flaring.
The model predicts that total network hash rate will reach 765 EH/s by the end of 2025, up from 684 EH/s today. In a long-term scenario where stranded energy sources are maximized, the network could stabilize at this level by 2050.
Hash price—the daily revenue generated per PH/s of hash rate—has hit multi-year lows. Projections suggest it will fluctuate between $32–$50 per PH/s per day through 2028, remaining under pressure until the next halving.
Bitcoin Mining vs. Direct Investment: A Profitability Crossroads
Is it better to mine Bitcoin or simply buy it? For many investors and operators, direct ownership may now offer superior returns.
A standard 1 MW containerized mining project costs approximately $740,000**, equipped with efficient ASICs like the Canaan Avalon A1566. Assuming Bitcoin reaches **$130,000 by 2026 and electricity stays at the industry average of 4.5 cents/kWh, capital recovery occurs within 27 months. However, over a four-year horizon, direct investment in Bitcoin outperforms mining returns under current conditions.
To close this gap, miners would need substantially higher fee income. Currently, transaction fees represent only about 5% of daily block rewards. To match buy-and-hold returns, fees would need to rise to 70% of daily issuance within four years—a significant shift requiring either network congestion or fundamental changes in usage patterns.
This raises operational dilemmas around curtailment strategies: pausing operations during low-fee periods risks missing high-reward blocks, undermining potential gains.

Cost Leadership and Competitive Differentiation
Efficiency is now the primary determinant of survival in Bitcoin mining. Cost disparities among operators reflect differences in energy sourcing, infrastructure design, and operational execution.
- Cormint, a private miner, leads with a production cost of $16,700 per BTC**, dropping to **$14,900 when excluding non-energy expenses. Its success stems from hybrid cooling (70% air-cooled, 30% immersion), proprietary software optimization, and in-house energy management that avoids third-party curtailment costs.
- TeraWulf ranks second at $18,700 per BTC**, thanks to its Nautilus nuclear-powered facility and a fixed **$0.02/kWh electricity contract valid through August 2027.
- In contrast, Riot Platforms reports one of the highest costs at $65,900 per BTC**, though effective curtailment programs reduce this to **$49,500.
These figures underscore how strategic advantages—like access to low-cost power and participation in demand-response programs—can dramatically alter cost profiles.
Hash Cost: A Better Metric for Operational Efficiency
While BTC production cost is widely cited, hash cost offers a clearer view of daily operational efficiency. It measures how much a miner spends per PH/s of hash rate per day:
Hash Cost = ($/kWh) × (efficiency in W/T) × 24 hours
Unlike production cost, hash cost isn’t affected by halvings—it reveals whether companies are truly improving their cost structure amid falling revenues.
Cormint again leads in this metric, having reduced its total hash cost by 31% since Q3 2023, reflecting sustained improvements in energy efficiency and infrastructure scaling.
Riot’s participation in ERCOT’s demand-response and 4CP programs generated $13.9 million in curtailment credits in Q2 2025, significantly lowering net power costs. These strategies highlight how smart grid integration can turn energy volatility into a financial advantage.
Capital Efficiency and Financial Sustainability
Long-term viability hinges not just on low costs but on capital discipline. Many miners burn through cash rapidly due to aggressive expansion, high SG&A expenses, and reliance on equity financing.
The most efficient capital allocators generate lasting shareholder value for every dollar raised. In Q2:
- Hut-8 was the only miner to reduce cumulative losses, driven by strong operational performance and $7.5 million in unrealized gains from financial assets.
- Companies like Core Scientific and Iren saw extreme negative ratios (-1068%, -3836%), indicating heavy losses despite minimal new funding.
- Bitdeer maintained flat cumulative losses, signaling improved fiscal control.
Free cash flow (FCF) yield remains a vital health indicator. Miners integrating AI workloads—such as Core Scientific via its 12-year, $8.7 billion agreement with Coreweave—are achieving positive FCF yields. These “mullet miners” (AI in front, mining in back) enjoy stable, predictable revenue streams that support growth without shareholder dilution.
Conversely, firms like Argo and Stronghold have cut back operations to meet debt obligations—achieving positive FCF but sacrificing scalability.
Strategic Infrastructure Expansion: Buy vs. Build
In 2025, acquiring existing infrastructure has proven more cost-effective than greenfield development:
- Cleanspark: ~$330,000/MW (wind-cooled acquisitions)
- Marathon: ~$450,000/MW
- Riot: ~$881,000/MW (Corsicana immersion project)
Purchasing distressed or turnkey sites allows faster deployment and lower entry costs. Meanwhile, AI-focused builds come at a premium—around $1.5 million/MW—due to high-density liquid cooling and redundant power systems.
TeraWulf’s CB-1 project exemplifies this shift: a 20 MW HPC/AI-ready facility with fiber redundancy and support for over 90 kW per rack, scalable to 145 kW via PDU upgrades.
