Bitcoin Miners Are Going Dark as Hash Revenue Falls 35% — ROI Now Tops 1,000 Days

Hashprice is the expected daily revenue per unit of mining power. In practice, it’s measured in USD per unit of hashrate per day (e.g. dollars per PH/s/day) and reflects how much a miner can earn from block rewards and fees for one petahash of computing power.

As one mining analytics firm explains, “hash price [is] the USD revenue per PH/day of hashpower”. In recent months, hashprice has collapsed from roughly $55 per PH/s/day in Q3 2025 to about $35 per PH/s/day by early December 2025, a drop of roughly 30–35%.

Several factors have driven this decline:

• Bitcoin price decline: After hitting an all-time high above $126,000 in October 2025, Bitcoin’s price fell about 35% to around $81,000 by late November. A lower BTC price means each block reward is worth less in USD, directly cutting miner revenue.
• Higher network difficulty: The network’s mining difficulty reached record highs (156 trillion in early Nov 2025, +6.3% over the prior adjustment). Higher difficulty means more total hashing power competes for the same rewards, so each miner earns fewer coins per unit of power.
• Halving: The April 2024 halving cut the block subsidy from 6.25 BTC to 3.125 BTC per block. This permanently reduced the mining reward by 50% overnight, shrinking the mining “pie” that miners compete for.
• Low transaction fees: On-chain transaction fees have been exceptionally low, contributing virtually nothing to miner revenue. Fees recently averaged only a few hundredths of a BTC per block (about 0.0197 BTC on average, or 0.63% of block rewards). One analysis notes fees are at “multi-year lows” (4 satoshis/vbyte), offering minimal relief.

These combined pressures, a 50% reward cut, weak BTC prices, near-record difficulty, and negligible fees, have pushed hashprice to historical lows. As one data provider notes, hashprice is now at five-year lows ($34–36/PH/day) even as difficulty stays near all-time highs. In short, miners are each getting a far smaller slice of the revenue pie than they were a year ago.

Notably, Ethereum co-founder Vitalik Buterin also commented on Bitcoin’s mining scale, writing on X:

Why Are Bitcoin Miners Shutting Down in 2025?

With revenues so depressed, many miners simply can’t cover costs. Recent estimates put large public miners’ all-in cost of production at roughly $44 per PH/s/day, while revenue is only $35–38 per PH/s/day.

In other words, the industry is predominantly mining at a loss. In practice this means miners are burning through cash reserves with every hour of uptime.

Faced with those math, many operators are powering down machines. In the past week, social media and industry reports have shown evidence of widespread rig shutdowns and sales of excess mining gear. The hash ribbon indicator, a technical metric that tracks two moving averages of Bitcoin hashrate, has recently “flashed a historically significant miner capitulation signal.”

This crossover (the 30-day hash rate moving average dipping below the 60-day average) suggests unprofitable miners are shutting down equipment en masse and may be liquidating Bitcoin holdings to cover losses. Historically, such a signal tends to coincide with the end of mining capitulations and has preceded price bottoms.

Several factors explain why shutdowns are spiking now:

• Cash-flow crunch: Even the newest, most power-efficient rigs can barely break even. At a hashprice of $35–38/PH/day, analysts say that “even the most efficient rigs barely cover electricity costs” at typical industrial power rates. In concrete terms, with 17–22 J/TH efficiency rigs (like the latest Bitmain S21 or MicroBT M60), miners need electricity below $0.05–$0.06/kWh just to break even. Many do not have that privilege, so each machine running cuts into capital.
• Long payback times: The payback period (or return-on-investment) for mining gear has exploded. New-generation rigs now have ROI > 1,000 days at current margins. In simple terms, that’s nearly three years of continuous mining to recover the purchase cost, far longer than reasonable. In comparison, during the 2017 Bitcoin bull run similar machines paid for themselves in just 3–6 months. With ROI so stretched, many miners prefer to just turn machines off to avoid sinking more money.
• Short-term tests fail: Miner operators often apply simple “cash-flow” and “payback” tests. At today’s hashprice and mid-range power costs, “many operators mine at a loss” and even modest declines would push setups negative. In short, every extra block mined may deepen the loss, so shutting off losing rigs is the only option.
• Capitulation dynamics: As shutdowns mount, the network hashrate has already begun to drop from its all-time high. The hash ribbon capitulation signal implies we’re entering a true miner capitulation phase. Similar capitulations in 2021 and 2022 eventually forced difficulty down and laid the groundwork for price recovery. For now, though, the signal underscores how dire conditions have become.

So Bitcoin miners are shutting down rigs because revenues have fallen well below operating costs, making continued mining a losing proposition. The situation is confirmed by on-chain metrics (hash ribbons) and by miners’ own actions (turning machines off or selling gear).

Who Will Survive the Bitcoin Mining Squeeze in 2026?

In this squeeze, survival favors the leanest operations. Analysts stress that “survivorship favors low-cost, well-capitalized miners”. In practice, that means:

• Cheapest power: Miners with access to ultra-low electricity rates are best positioned. One industry note flags a key threshold: sustainable mining in 2025 now requires around $0.06 per kWh or lower. Many large miners have legacy power contracts below these levels; others may buy or build renewable projects to hit this mark. Smaller players paying $0.08–$0.10/kWh simply cannot survive this cycle.
• Efficient hardware: Only the newest, most energy-efficient ASICs (sub-20 J/TH) make sense at current hashprices. Firms running older, less efficient rigs (e.g. +30 J/TH machines) are uncompetitive. Weaker rigs are being idle while newer fleets keep crunching, albeit at a loss.
• Strong balance sheets: Miners with deep pockets, hedges, or other revenue streams can withstand more bad months. Companies that have hedged future production or have diversified holdings (e.g. Bitcoin reserves) are less desperate to sell. By contrast, miners burdened by debt or dependent on continuous cash flow are being forced into shutdown or fire sales of equipment.
• Diversification into AI/Data centers: Unusually, many large miners are pivoting part of their business into high-performance computing (HPC) and AI hosting. Companies like Core Scientific, IREN, Hive Digital, Riot, and Hut 8 have inked deals to retrofit excess capacity for AI GPUs and data-center services. For example, Core emerged from bankruptcy to become an AI infrastructure provider, and IREN signed massive contracts with Microsoft and Dell to host compute services. This allows them to utilize their grid connections and facilities for more profitable workloads while keeping lights on.
• Consolidation: The tough market is accelerating mergers and acquisitions. Smaller or marginal outfits are being bought or shut. Given this, you should expect “more shutdowns, consolidation and distressed sales” as weak players exit. Historical precedent (e.g. 2018–2020) suggests the industry will end up with a smaller number of large, efficient firms once the dust settles.

In short, the miners best equipped for 2026 will be those with

• Very low power costs (around $0.06/kWh or less),
• Top-notch ASIC efficiency, and
• Enough capital to weather prolonged losses.

Firms that can repurpose assets or diversify revenue (such as into AI hosting) also have an edge. Many others, unfortunately, will either be forced offline or exit the market altogether.

What Does a 1,000-Day ROI Mean for New Bitcoin Mining Equipment?

ROI (return on investment) in mining typically refers to how long it takes for a miner to earn back the cost of a new rig. At current economics, payback periods have blown out to around 1,000 days or more for even the latest ASIC models.

To put that in perspective: buying a top-tier Antminer S21 or MicroBT M60 today would take nearly three years of constant operation at today’s hashprice to break even.

Crucially, that is longer than the time to the next block subsidy halving. With roughly 850 days until the 2028 halving, any machine bought now will still be mining on the old reward schedule when that halving happens (which cuts future revenue in half). In practice, this means new equipment is unlikely to ever pay for itself unless conditions improve sharply.

The implication is severe: new hardware purchases have become much riskier and less attractive. During the last major bull market (2017), ROI for new rigs was measured in just a few months, so investment was easy to justify.

Now, with ROI measured in years, only miners with exceptionally low costs or alternative revenue see any hope of hardware recouping its cost. Many operators may opt to stop expanding hardware fleets and instead mine with existing rigs at the lowest possible cost, or simply hold BTC as an alternative investment.

In short, a 1,000-day ROI means that, at current mining revenue levels, a new ASIC is on track to not pay back its purchase before the next halving occurs.

New equipment bought today would effectively be mining with half the reward by the end of its payback period, making the break-even point even more elusive. This dynamic strongly discourages new investment in rigs until the hashprice outlook improves.
