Yes, Bitcoin mining is facing a real profitability crisis—but it is a severe margin squeeze and industry restructuring, not proof that mining is about to end. Older machines, expensive electricity and debt-heavy operations are most exposed. Efficient fleets with low-cost or flexible power can still earn operating cash, while some public miners are trying to diversify into AI and high-performance computing (HPC). That pivot may help, but it is not guaranteed revenue.
The central question is not whether every miner is profitable. It is whether a particular machine, at a particular site and power price, can earn more than its operating costs—and whether it can also recover its purchase and facility costs. Those are different tests.
What the crisis looks like in the numbers
The clearest sign of pressure is hashprice: the expected daily revenue from a unit of mining power. CoinShares reported that Bitcoin hashprice fell from about $63 per PH/s per day in July 2025 to roughly $28–$30 in early March 2026, before recovering into the $30–$35 range later in its reporting period. It described the conditions as the most difficult since the April 2024 halving. These figures describe the report’s period, not a verified snapshot for August 16, 2026; hashprice changes with Bitcoin’s price, fees and network difficulty. CoinShares’ Q1 2026 mining report
What’s actually slowing this PC down?

At about $30/PH/s/day, CoinShares estimated that miners with efficiency below an Antminer S19 XP operating at electricity costs of $0.06/kWh or more were losing money. Its estimate placed this equipment at roughly 15%–20% of the global fleet. Newer machines below about 15 joules per terahash (J/TH) could retain operating margins at ordinary industrial power prices, while older generations generally needed electricity below about $0.05/kWh to remain cash-profitable. These are estimates under stated market assumptions—not universal break-even rules. Machine condition, actual power draw, fees, uptime, cooling, hosting and contract terms all matter.

In short, the squeeze is uneven. High-cost, older and debt-financed operators face acute pressure; operators with unusually cheap, fixed or interruptible power may keep running. Some miners can also earn revenue from curtailment or other power-market arrangements. Hashrate can remain high even while margins are poor.
Hashprice, machine revenue and profit are not the same
Hashprice is a market-wide revenue measure, commonly quoted in U.S. dollars per petahash per day (USD/PH/s/day). It is not the profit of a specific machine. A machine’s approximate daily gross mining revenue is:
Daily revenue = ASIC hashrate in PH/s × hashprice in USD/PH/s/dayOne PH/s equals 1,000 TH/s. Hashprice reflects the expected value of mining output and is affected by Bitcoin’s price, the block subsidy, transaction fees and network difficulty. Luxor’s hashprice documentation explains the metric and its inputs.
Electricity cost can be estimated separately:
Daily electricity cost = power draw in kW × 24 × electricity price per kWhThen subtract pool fees, hosting, cooling, repairs, labor and other operating expenses to estimate operating cash profit. A positive result does not establish that buying the ASIC is a sound investment. A full-cost analysis also considers the machine’s purchase price, shipping and customs, electrical work, facility costs, financing, taxes, downtime and eventual replacement.
Energy-only break-even example
For an ASIC rated at H TH/s, drawing P kW, with hashprice R USD/PH/s/day and a combined deduction rate F for pool fees and other revenue-based charges, an approximate energy-only break-even power price is:

Revenue per day = (H / 1,000) × R
Energy-only break-even $/kWh = Revenue × (1 − F) / (P × 24)This calculation omits fixed hosting, repairs, capital recovery and other costs. Use actual site power draw rather than relying only on a manufacturer’s rating. Do not treat one daily-profit figure as durable unless its date, hashprice, Bitcoin price, electricity location, uptime, hardware configuration and included costs are clear.
Why mining margins have been squeezed
1. The halving cut the block subsidy
Following the April 2024 halving, the Bitcoin block subsidy is 3.125 BTC per block. The subsidy halves every 210,000 blocks; the next halving is projected for April 2028, with the exact date dependent on block production. A halving reduces newly issued bitcoin paid to miners. Unless Bitcoin’s price, fees or mining efficiency rises enough to offset the reduction, the same infrastructure earns less subsidy revenue.
2. Hashrate and difficulty kept competition intense
The halving did not switch off competing machines. Miners may keep operating because their ASICs and facilities are already paid for, their power is cheap or contractually fixed, they have debt obligations, they expect prices to recover, or they value holding bitcoin. Some operations may be strategically or state-backed, and manufacturers may run fleets to absorb hardware inventory. These factors help explain why high hashrate does not disprove a profitability crisis: hashrate measures computation and competition, not profit.
More competition means each unit of hashrate generally earns a smaller share of block rewards. CoinShares reported that high difficulty and rising hashrate diluted production per machine. MARA likewise attributed changes in its production and energy cost per bitcoin partly to the 2024 halving and higher global hashrate and difficulty. MARA’s 2025 annual filing
3. Transaction fees have not replaced the subsidy
CoinShares reported that transaction fees were consistently below 1% of total block rewards during the period it analyzed, averaging about 0.018 BTC per block. Fees vary, so that is a period-specific observation, not a permanent condition. When blocks are less congested, users may pay less to have transactions included, which is good for users but leaves miners with less fee revenue. Over the long term, transaction fees become increasingly important to miner revenue as block subsidies decline.

4. Bitcoin’s price fell while costs remained
MARA’s 2025 annual filing said Bitcoin fell from about $126,000 to a low near $60,000 during Q4 2025 and Q1 2026. A lower BTC price cuts the dollar value of mined bitcoin, while many costs—electricity, leases, wages, maintenance and debt service—are payable in fiat currency. A specific market price is a snapshot; it should not be substituted for the price over a miner’s accounting period.

These are company-specific energy figures, not a universal cost to mine one bitcoin. MARA’s Q1 2026 filing
6. Older ASICs lose ground to more efficient models
Mining economics depend on how much hashrate a machine produces for the power it consumes. Newer ASICs can produce more hashes per watt, putting older equipment at a disadvantage even when it still works. Operators face a difficult capital decision: continue running old machines while they cover marginal costs, or spend heavily on replacements that could themselves lose value as difficulty rises or market conditions change. A functioning machine is not necessarily a competitive or profitable one.
Who is most exposed—and who has a better chance?
| More exposed | Better positioned, all else equal |
|---|---|
| Older-generation ASICs, including S19-era or earlier fleets | Efficient, newer-generation hardware |
| Power above roughly $0.06/kWh for older equipment, especially with extra fees | Very low-cost power; below roughly $0.05/kWh can matter for older fleets, depending on conditions |
| Residential-rate or opaque hosted power | Industrial power with transparent, fixed or hedged terms |
| High-interest debt, limited liquidity or a need to sell mined BTC immediately | Low leverage and sufficient liquidity to withstand downturns |
| Low uptime, poor cooling, frequent repairs or demand charges | Reliable operation and the ability to curtail when power is expensive |
| No alternative use for the site or power connection | Credible, funded alternatives such as contracted data-center workloads |
The table is a risk guide, not an individual profitability verdict. Even a low headline power price may exclude transmission, demand charges, taxes, hosting, seasonal rates, minimum-use commitments or curtailment conditions. Conversely, a higher power price may be partly offset by demand-response income or flexible shutdowns.
Why difficulty adjustment helps survivors—but not immediately
Bitcoin adjusts mining difficulty approximately every 2,016 blocks to target an average block interval of about ten minutes. If enough miners shut off, blocks can initially arrive more slowly. At a subsequent adjustment, difficulty can fall, allowing the remaining miners to earn a larger share of block rewards per unit of hashrate.

This is a relief mechanism, not instant insurance. A miner may have to operate through losses until an adjustment, and the amount of relief depends on how much hashrate leaves and whether other operators add machines. Falling difficulty can make marginal equipment viable again, but higher Bitcoin prices can also attract machines back and raise competition. The result is a painful feedback cycle, not necessarily a permanent downward spiral.
How to read public miners’ cost figures and BTC sales
“Cost per bitcoin” can mean several different things:
- Energy cost: electricity consumed by mining equipment.
- Cash production cost: energy plus some combination of hosting, maintenance, pool fees and operating expenses.
- All-in corporate cost: potentially including depreciation, corporate overhead, interest, taxes, construction and other investment.
These figures are not comparable without checking the company’s definition and reporting period. CoinShares cautioned that AI/HPC construction and overhead can distort per-bitcoin costs at hybrid companies when costs are compared with a shrinking Bitcoin-production base. MARA, for example, reported a defined operating-cost metric of $27.60 per PH/s per day in Q1 2026 and purchased energy costs of $40,047 per bitcoin. The units and definitions differ; neither should be read as the other or as a complete all-in cost measure.
Under pressure, miners may sell newly mined bitcoin or treasury holdings, borrow against bitcoin, issue equity or debt, reduce capital spending, delay upgrades, curtail machines, sell assets or seek other customers. CoinShares reported that listed miners in its analysis had reduced BTC treasuries by more than 15,000 BTC from peak levels, including sales reported by Core Scientific, Bitdeer and Riot. A treasury sale is not, by itself, proof of insolvency: companies also sell to fund expansion, repay debt, meet taxes or fulfill other obligations.

Mining sites can be attractive to data-center customers because they may already have industrial land, grid connections, substations, fiber, cooling and experienced operators. But an electricity connection is not an AI data center. High-performance computing may need different cooling, denser power delivery, networking, specialized buildings, GPUs, construction capital and demanding service levels.

A proposed project or site’s potential is not proof of contracted or current AI revenue. MARA’s filing describes power, regulatory, internet, equipment-supply and energy-price risks relevant to both mining and data-center operations.
Does the squeeze threaten Bitcoin’s security?
Not automatically. A miner losing money does not mean blocks have stopped or that Bitcoin has suffered a security failure. Difficulty adjustment is designed to keep block production near its target as miners enter and leave. The more plausible concerns are gradual: mining could concentrate among operators with the cheapest power and best financing; pools, geography or equipment supply could become more concentrated; and fewer miners may be willing to invest in capacity.
Those risks should be discussed specifically rather than inferred from a profitability estimate. Hashrate alone does not reveal who controls mining, whether operators are profitable, or how geographically concentrated facilities are. Longer term, Bitcoin’s security budget also faces the question of how transaction fees will contribute as block subsidies continue to decline.

What could improve profitability—and why none is a sure fix
- A higher Bitcoin price: raises the dollar value of mined BTC, but rising prices can bring more hashrate online and lift difficulty, diluting the benefit.
- A decline in hashrate and difficulty: can improve revenue per unit of capacity for survivors, but only after the network’s adjustment and with uncertain timing.
- Higher transaction fees: add revenue without requiring a larger subsidy, but fee income is volatile and depends on demand for block space.
Operators can also improve their own position with more efficient machines, better power terms, reliable uptime and flexible curtailment. None of these eliminates capital costs or guarantees a positive return.
A practical decision checklist
If you are considering an ASIC
- Calculate with your actual electricity rate, including delivery, demand charges, taxes and hosting—not just an advertised energy price.
- Verify the exact model, condition, real hashrate and power draw. Include shipping, customs, installation and repair risk.
- Check electrical capacity, ventilation, heat, noise, internet reliability and local rules before buying.
- Run several scenarios for BTC price, hashprice, difficulty, fees and uptime. Do not assume difficulty stays constant.
- Separate operating cash flow from payback on the ASIC and facility. If the purchase only works with a guaranteed BTC-price increase, the economics are speculative.
- Do not trust promised fixed mining returns or send funds to an unverified cloud-mining platform. A calculator cannot validate a provider or contract.
At residential electricity prices, especially above roughly $0.08–$0.10/kWh, a standalone ASIC purchase is often difficult to justify; the actual result still depends on hardware, fees and power terms. Hosted mining requires its own full cost and contract review. Check service terms for machine ownership, repairs, downtime, curtailment, contract length and exit rights. A hosted customer’s payout is revenue, not net profit.
If you already operate a fleet
- Measure marginal cash cost per PH/s per day and compare it with current, dated hashprice.
- Use the all-in power price, including demand charges and curtailment or take-or-pay terms.
- Identify which machines are below operating break-even; distinguish that from machines failing to recover capital cost.
- Review fleet-weighted J/TH, uptime, repair frequency and cooling overhead.
- Model monthly BTC sales, liquidity, debt maturities and the effect of BTC remaining below your base case.
- Assess whether curtailment, power-market income or facility upgrades improve returns after their costs.
- Treat AI/HPC revenue as contracted or realized only when the evidence supports that label.
If you are evaluating a public miner
Look beyond BTC mined, total hashrate, market capitalization or a headline cost-to-mine figure. Review the company’s cost definitions, energized versus installed hashrate, machine efficiency, power contracts, BTC treasury policy, debt maturities, dilution, capital spending, curtailment income and geographic and regulatory exposure. For an AI/HPC pivot, distinguish signed customer commitments and recognized revenue from announced capacity and projections.
The verdict
Bitcoin mining profitability is under real pressure, but there is no single global break-even price that describes every operator. The key divide is between marginal operating cash flow and full investment returns: some miners can keep earning cash while failing to recover what they spent on hardware and facilities. Difficulty adjustment can ease pressure after inefficient capacity exits, while the halving and low fee revenue make the business more dependent on efficient equipment, favorable power and disciplined capital. Mining is not disappearing; the economic cutoff is moving upward.
