Bitcoin Mining Difficulty Stays 5% Below Peak for Over a Year

Bitcoin mining difficulty has remained beneath its all-time high for upwards of a year. As of November 8, 2026, the metric sits just above 148 trillion—roughly 5% lower than the 156 trillion peak recorded on October 29, 2025.

This represents the longest recordless period in the history of Bitcoin, eclipsing a roughly 364-day span that occurred between August 2011 and July 2012. The wider industry now faces a pressing question: is this simply a temporary phase in the mining cycle, or have operators found more lucrative returns by shifting capital toward AI data centers and high-performance computing?

Bitcoin Mining Difficulty Sets a Recordless-Streak Record

The key facts behind the new record

On October 29, 2025, Bitcoin mining difficulty peaked at nearly 156 trillion, and the network has not matched that level since. By November 8, 2026, the metric had receded to just over 148 trillion.

While the 5% gap is modest, the duration is what truly stands out. Bitcoin has now comfortably surpassed its historical benchmark for the longest continuous timeframe without a new difficulty high, a streak initiated directly following the October 2025 peak.

What Bitcoin mining difficulty measures

Difficulty adjusts dynamically as computing power enters or exits the network, ensuring that block generation remains anchored near the 10-minute target. A lower reading relative to a prior peak signifies that overall mining conditions have not fully regained their previous high-water mark.

For operators, a higher difficulty level diminishes the probability of securing a block using a fixed amount of hash rate. When expenses related to hardware, electricity, and financing remain elevated, this pressure directly impacts revenues.

Saifedean Ammous and Core Scientific Point to Structural Pressure

Ammous links the slowdown to mining economics

Saifedean Ammous, author of The Bitcoin Standard, notes that the current slowdown represents the most extended dry spell in Bitcoin history. In his view, the sector is confronting systemic structural pressures rather than a single acute shock, unlike previous downturns.

He highlights the impact of Bitcoin’s halving cycles. Because block subsidies are cut in half roughly every four years, the price of Bitcoin must appreciate rapidly enough to compensate for the reduced reward. Ammous estimates that mining economics require nearly 19% annual appreciation across a four-year window, even before factoring in dollar devaluation and the opportunity costs associated with competing infrastructure industries.

Core Scientific is redirecting capacity to AI

Core Scientific serves as a prime example of this shift. The organization recently announced intentions to fully abandon Bitcoin mining by the conclusion of 2026, positioning itself in 2027 as a dedicated colocation provider for AI and high-performance computing.

The firm has already trimmed its proprietary mining fleet by nearly half while rerouting data-center space and power supplies to infrastructure clients. During the third quarter, colocation revenue surged 58% quarter over quarter to $215.4 million, a sharp increase from the $15 million reported during the same period a year earlier.

CryptoPotato originally reported on this difficulty milestone and the evolving economic realities confronting Bitcoin miners.

Background: Earlier Difficulty Downturns Had Clearer Triggers

The 2011–2012 precedent

The previous record for a prolonged difficulty drought spanned roughly 364 days, stretching from August 2011 to July 2012. Throughout that period, the price of Bitcoin crashed by approximately 94% to 95%, providing a straightforward rationale for the degradation in mining profitability.

Conversely, the current stretch has endured far longer in the absence of a comparable price collapse or a single catalyst forcing miners to relocate en masse. This divergence is precisely why market observers are closely monitoring the latest difficulty patterns.

The 2021 China mining ban

Another major disruption materialized in 2021 when Chinese authorities enacted an outright ban on domestic cryptocurrency mining. That mandate compelled a massive fraction of global hash rate to migrate elsewhere, causing a sharp structural break in the geographic distribution of Bitcoin mining.

While the 2021 episode was driven by distinct regulatory intervention and forced geographic relocation, today’s difficulty streak is tied up with subsidy pressures, intense competition for electrical power, and the surging commercial value of data-center real estate.

How the 2023 growth cycle lifted difficulty

Historically, the network has moved in the opposite direction during periods of price recovery paired with heightened Ordinals activity. As miners deployed fresh hardware, network computing power expanded, propelling difficulty to successive new highs.

An earlier mining report linked the 2023 upswing in difficulty to appreciating Bitcoin prices and Ordinals-driven demand for block space, alongside the deployment of next-generation machines as rack space became accessible.

That prior analysis also detailed how escalating difficulty directly influences an individual miner’s likelihood of earning block rewards.

Why the Bitcoin Mining Difficulty Streak Matters

Halving pressure is increasing

Each successive halving halves the block subsidy. To maintain facility profitability, operators must consistently find methods to drive down operational expenses, enhance machine efficiency, or rely on higher Bitcoin valuations.

Ammous’s projection of roughly 19% annualized appreciation reflects the pace of value growth he believes is necessary for mining over a four-year horizon. This figure serves as an analytical estimate for sector economics rather than a formal price prediction for Bitcoin.

AI infrastructure is becoming a direct competitor

Artificial intelligence firms are actively competing for the identical pools of affordable electricity, data-center square footage, and power grid infrastructure traditionally utilized by miners. If AI colocation yields superior margins, operators can easily reallocate their facilities and capital away from deploying additional Bitcoin mining rigs.

This dynamic shifts the opportunity cost of mining. A physical site once deemed attractive for hosting ASIC hardware is now continuously weighed against the lucrative demand presented by high-performance computing clients.

The energy debate could shift

According to Ammous, suppressed mining economics could naturally subdue electricity consumption, potentially softening one of the most frequent criticisms lobbed against Bitcoin. The identical market pressures that reduce the appeal of mining operations might simultaneously bolster alternative arguments regarding the network’s overarching energy footprint.

Whether this materializes depends heavily on how much capacity departs from mining versus what enters elsewhere, alongside whether Bitcoin pricing ultimately provides sufficient incentives for operators to resume expansion.

The Numbers Show Mining Capacity Is Being Repriced

The difficulty gap is modest, but the duration is exceptional

Standing at slightly above 148 trillion, the current metric is roughly 5% shy of the near-156-trillion record. A divergence of that magnitude would not normally signal a fundamental industry rupture on its own, but its persistence for over a year—surpassing the ~364-day record set in 2011–2012—makes it notable.

The combination of elapsed time and the absence of a new peak forms the core signal. Miners have yet to guide the network back to the computing power thresholds observed during the October 2025 high.

Core Scientific’s revenue mix has changed sharply

Core Scientific’s colocation revenues climbed to $215.4 million in the third quarter, representing a 58% quarter-over-quarter increase. This compares starkly to the $15 million recorded during the same period a year earlier, illustrating precisely why high-performance computing clients can successfully compete against Bitcoin miners for vital facility space and power resources.

These metrics stem from the colocation business that Core Scientific has aggressively scaled around AI and alternative computing workloads. The firm’s planned exit from mining underscores this trend as one of the clearest corporate-level manifestations of the broader market pressures highlighted by Ammous.

The subsidy and price equation remains central

The mandatory 50% subsidy reduction accompanying every halving acts as a recurring stress test for miners. Should the market price of Bitcoin fail to scale accordingly, operators must heavily depend on efficiency gains, discounted energy tariffs, favorable hosting deals, or repurposing their infrastructure for alternative tasks.

Ammous’s estimate of nearly 19% annual appreciation over four years frames this mathematical challenge clearly, emphasizing that mining must compete not just peer-to-peer, but against the simplicity of holding spot BTC and the non-mining yields of modern infrastructure.

Risks and Open Questions Around the Mining Slowdown

Temporary cycle or lasting migration?

This recordless window could theoretically close if Bitcoin pricing, equipment efficiency, or available energy supplies improve sufficiently to catalyze another surge in computational power. Conversely, the alternative is a prolonged migration of capital and power toward AI infrastructure and general data-center clients.

The current data pattern alone does not definitively resolve this question; it merely demonstrates that the network has lingered beneath its prior difficulty peak for an unusually extended timeframe while operators continually evaluate where their facilities can generate the highest returns.

AI may raise the cost of staying in mining

Because AI infrastructure providers can frequently offer superior profitability for data centers and power access, mining enterprises may find it increasingly difficult to justify fresh capital expenditures on hardware—especially in the wake of halvings that diminish per-block rewards.

A weaker difficulty record is not the same as a weaker Bitcoin network

Mining difficulty can remain subdued below historical highs while the underlying Bitcoin network continues to function and process blocks smoothly. The metric merely tracks computational competition at a specific moment in time; it does not inherently indicate fundamental weakness within Bitcoin.

Offering a counterperspective to bearish narratives, Ammous suggests that if mining becomes less lucrative than simply holding BTC, capital that might otherwise have been sunk into hardware, real estate, and electricity could flow straight into the digital asset itself.

What Happens Next for Bitcoin Mining

Core Scientific’s deadline

Core Scientific aims to finalize its departure from Bitcoin mining by the end of 2026, transitioning fully into an AI and high-performance-computing colocation provider as it enters 2027, making this end-of-year milestone crucial for corporate strategy.

The difficulty level to watch

To officially break the ongoing recordless period, Bitcoin mining difficulty must surpass the nearly 156 trillion threshold established on October 29, 2025. Until that milestone is cleared, the network will continue pushing the boundaries of its longest stretch without a new difficulty high.

The industry’s competing investment choices

Miners will continue balancing traditional Bitcoin mining against AI colocation and alternative data-center applications. Key variables moving forward will include Bitcoin price momentum, upcoming subsidy adjustments, machine efficiency metrics, and the profitability offered by non-mining infrastructure clients.

Ultimately, this recordless streak serves as both a technical mining statistic and an indicator of changing capital allocation strategies across the sector.
