The upcoming Bitcoin halving in 2025 is poised to reshape the mining landscape, with rising operational costs and shrinking rewards pushing many miners toward financial strain. A recent report by CoinShares sheds light on the growing challenges facing Bitcoin mining firms, projecting that the average production cost per BTC will reach **$37,856** post-halving. At current price levels below $40,000, only a select few mining companies are expected to remain profitable.
This in-depth analysis explores the shifting cost structures, identifies the most resilient miners, and examines broader market dynamics affecting miner behavior ahead of the halving.
Projected Average Mining Cost: $37,856
With less than 90 days before the 2025 halving, CoinShares has analyzed network difficulty, hash rate efficiency, and energy consumption trends to estimate that the break-even cost for Bitcoin mining will rise to $37,856 per BTC**. This represents a significant increase from previous cycles — during the 90-day window before the 2020 halving, average production costs ranged between **$7,600 and $7,900.

Bitcoin’s protocol adjusts mining difficulty approximately every two weeks to maintain a consistent block time of 10 minutes. As more miners join the network or upgrade their hardware, total computational power (hash rate) increases, leading to higher difficulty levels. While this ensures network stability, it also raises the bar for profitability — especially when block rewards are cut in half.
During previous halvings, miners with inefficient operations or high electricity costs were gradually forced out of the market. The same pattern is expected in 2025: as difficulty remains elevated and revenue per block declines, miners operating above the cost curve will face mounting losses.
Structural Challenges Facing Modern Mining Firms
Despite advancements in mining technology, CoinShares highlights a critical flaw in the current strategies of many mining companies: overreliance on hardware upgrades without addressing core cost inefficiencies.
While firms are aggressively purchasing next-generation ASIC miners to boost hash rate output, they often overlook the fundamental issue — energy consumption. Upgraded equipment still requires substantial power to operate, and without access to low-cost electricity, profit margins remain thin.
"Most mining firms are increasing their overall efficiency in terms of watts per terahash (W/T), but their underlying cost structures aren't improving," the report notes. "Post-halving, even with new machines, miners will need to consume more energy to mine the same number of bitcoins."
This creates a dangerous cycle: rising energy demands lead to higher operational expenses, which become unsustainable when BTC prices stagnate or dip below break-even levels.
Key Cost Drivers in Bitcoin Mining
CoinShares evaluated 14 publicly traded mining companies using data from U.S. SEC filings and financial statements, focusing on three primary cost components:
- Electricity & Energy Costs: Accounting for 68% to 71% of total expenses, this is by far the largest burden. Miners with access to cheap, renewable energy sources have a decisive advantage.
- SG&A (Selling, General & Administrative): Includes operational overheads such as salaries, office expenses, and corporate management. Non-cash items like stock-based compensation were excluded.
- Interest Expenses: Debt servicing costs, excluding lease payments or other financing charges.
To stay profitable post-halving, miners may be forced to slash SG&A spending, liquidate BTC reserves, or restructure debt — actions that could impact long-term growth and shareholder value.
The Five Miners Likely to Survive
Based on its analysis, CoinShares concludes that only five mining companies are positioned to remain profitable if Bitcoin trades below $40,000 after the halving:
- Bitfarms
- Iris Energy
- CleanSpark
- TeraWulf
- Cormint
These firms stand out due to their low-cost energy sources, efficient infrastructure, and conservative financial management. Among them, CleanSpark and TeraWulf are particularly well-prepared, leveraging renewable energy and strategic geographic placement to minimize power costs.

The report warns that all other miners may face severe pressure, potentially leading to:
- Liquidation of Bitcoin holdings
- Dilutive equity raises (issuing new shares)
- Debt conversion or restructuring
Such moves could erode investor confidence and trigger further market volatility.
“Unless Bitcoin’s price remains above $40,000, we believe only Bitfarms, Iris, CleanSpark, TeraWulf, and Cormint can sustain profitability.”

Miners Are Selling More BTC Than Ever
Despite bullish sentiment driven by the approval of Bitcoin spot ETFs and growing interest in Bitcoin ordinals, on-chain data reveals a troubling trend: miners are offloading BTC at an accelerating pace.
According to CryptoQuant, daily miner outflows spiked to 61,389 BTC on January 12, marking the highest single-day sell-off in over three years. This surge suggests that many mining operations are converting freshly mined coins into fiat to cover operational costs.
Bradley Park, analyst at F2Pool, commented that while increased selling is often seen as bearish, the correlation isn’t always clear-cut. However, sustained outflows could exert downward pressure on prices — especially during periods of low institutional buying.
Just before the ETF approvals in early 2024, Bitcoin miners accounted for 21.49% of on-chain transaction volume, the highest level since October 2019 (IntoTheBlock). This indicates strong short-term liquidity pressure within the mining sector.
Why Are Miners Selling?
- Rising Operational Costs: Electricity prices, maintenance, and debt obligations continue to climb.
- Reduced Block Rewards: Anticipation of lower income post-halving drives preemptive sales.
- Capital Needs: Some firms sell BTC to fund expansion or avoid insolvency.
While this behavior is rational from a business perspective, it may create temporary supply shocks in the market.
Frequently Asked Questions (FAQ)
Q: What is the Bitcoin halving?
A: The Bitcoin halving is a programmed event that occurs roughly every four years (every 210,000 blocks), reducing the block reward given to miners by 50%. In 2025, the reward will drop from 6.25 BTC to 3.125 BTC per block.
Q: Why does mining cost matter after the halving?
A: With revenue cut in half but operational costs remaining high (especially electricity), only miners with low production costs can remain profitable. Those above the cost curve risk shutdowns or bankruptcy.
Q: How is Bitcoin mining profitability calculated?
A: It depends on electricity cost per kWh, miner efficiency (J/TH), network difficulty, BTC price, and pool fees. Tools like ASIC profitability calculators help estimate daily returns.
Q: Can miners survive if BTC stays below $40K?
A: Only a handful can — those with sub-$38K break-even costs and strong balance sheets. Most will need to reduce expenses or sell reserves.
Q: Will miner sell-offs crash Bitcoin’s price?
A: Not necessarily. While increased supply can pressure prices short-term, macro factors like ETF inflows and institutional adoption often offset miner selling.
Q: How can miners reduce costs?
A: By relocating to regions with cheaper electricity (e.g., Texas, Iceland), using stranded or renewable energy, optimizing cooling systems, and refinancing high-interest debt.
