The Bitcoin market is witnessing a historic shift in miner behavior as prices surge to new all-time highs in 2025. Contrary to traditional patterns where large price rallies trigger significant sell-offs, today’s mining landscape tells a different story — one defined by restraint, strategic accumulation, and long-term confidence in Bitcoin’s value.
Rather than cashing out amid favorable market conditions, major Bitcoin miners are actively increasing their BTC reserves. This behavioral pivot signals a maturation of the mining industry and reflects deeper structural changes in how miners perceive profitability, sustainability, and market cycles.
Miners Accumulate Amid Declining Revenues
Despite Bitcoin’s price hovering near record levels — briefly touching $108,000 — miner revenues have been trending downward. According to recent data from on-chain analytics platform CryptoQuant, daily mining revenue dropped to $34 million on June 22, the lowest level since April 20, 2025.

This decline stems from two key factors: reduced transaction fees and a slight pullback in BTC’s price following its peak. Additionally, the network hashrate has fallen by 3.5% over the past 10 days — the most significant drawdown since July 2024, shortly after the last block subsidy halving event that cut mining rewards in half.
Yet, despite these financial pressures, miners are resisting the urge to sell.
“Bitcoin miners are the most underpaid they have been in the last year,” CryptoQuant noted in its Weekly Report. “However, miner selling is still muted in spite of lower revenues.”
In fact, total miner outflows — BTC transferred from miner wallets to exchanges — have plummeted from a daily high of 23,000 BTC in February 2025 to just around 6,000 BTC. There have been no instances of extreme outflows since early in the year, suggesting strong conviction among mining operations.
Strategic Reserves: Large Miners Buck the Trend
Miners holding between 100 and 1,000 BTC have collectively increased their reserves by 4,000 BTC since April — bringing their total holdings to 65,000 BTC, the highest level since November 2024.
This accumulation occurred even during periods of local price strength and volatility, underscoring a strategic shift toward balance sheet optimization. In previous bull runs, such price action would typically prompt widespread profit-taking. Now, miners appear to be treating Bitcoin as a long-term asset rather than a liquid revenue stream.
CryptoQuant attributes this “hodl” trend to an estimated 48% operating margin across the mining sector. With efficient operations and access to low-cost energy, many large-scale miners can afford to hold through short-term revenue dips, betting on future price appreciation.
Satoshi-Era Miners Enter Full Hodl Mode
One of the most striking developments in 2025 is the behavior of so-called “Satoshi-era” miners — early participants who mined Bitcoin during its infancy (2009–2012) when difficulty was low and adoption minimal.
Historically, these dormant wallets tend to activate after major price rallies, often interpreted as a bearish signal indicating that long-term holders are finally taking profits. However, in 2025, that pattern has reversed dramatically.
“Selling from Satoshi-era miners remains at low levels,” CryptoQuant reports. “These miners have sold only 150 Bitcoin so far in 2025, compared to almost 10,000 Bitcoin in 2024.”
This represents a staggering 98.5% reduction in sell pressure from one of the most watched on-chain cohorts. The data suggests that even the earliest adopters — those with the deepest cost basis advantage — are choosing not to distribute supply.

The implications are profound: if those who could exit with near-zero cost are staying put, it reinforces the idea that confidence in Bitcoin’s long-term trajectory is stronger than ever.
Why Are Miners Holding? Market Implications
Several factors explain this unprecedented restraint:
- Reduced Sell Pressure: With fewer coins hitting exchanges, available supply tightens — potentially supporting further price increases.
- Improved Operational Efficiency: Advances in ASIC technology and renewable energy integration have lowered break-even costs for many miners.
- Institutional Influence: Publicly traded mining firms now play a larger role, and their reporting standards encourage transparency and disciplined treasury management.
- Macro Confidence: Persistent inflation fears, geopolitical uncertainty, and growing institutional adoption continue to boost Bitcoin’s appeal as digital gold.

Additionally, earlier in June 2025, the Hash Ribbons indicator delivered its third confirmed “buy” signal of the year — a technical pattern that historically identifies capitulation points among unprofitable miners and precedes local price bottoms. Its appearance amid broader accumulation adds further credibility to the current bullish structure.
Frequently Asked Questions (FAQ)
Q: Who are 'Satoshi-era' miners?
A: These are individuals or entities that mined Bitcoin during its earliest years (2009–2012), often using basic hardware. Many remained dormant for years before moving coins during major bull markets.
Q: Why is low miner selling bullish for Bitcoin?
A: When miners hold instead of selling, less supply enters the market. This scarcity can drive prices higher, especially during periods of strong demand.
Q: Are miners really 'underpaid' at current prices?
A: Yes, according to CryptoQuant. Despite high BTC prices, declining transaction fees and post-halving revenue cuts have reduced daily income to two-month lows — yet miners aren’t panicking.
Q: What does 'miner outflow' mean?
A: It refers to Bitcoin being sent from known miner addresses to exchanges or other wallets. High outflows often precede price drops due to increased sell pressure.
Q: How reliable is the Hash Ribbons indicator?
A: Hash Ribbons has a strong historical track record in identifying miner capitulation and bottoming phases in previous cycles, making it a trusted tool among on-chain analysts.
Q: Could this trend reverse suddenly?
A: While possible, sustained accumulation across multiple miner tiers — including legacy holders — suggests structural confidence rather than short-term speculation.

Conclusion: A New Era of Miner Discipline
The current behavior of Bitcoin miners — particularly the dramatic reduction in sales by early-era participants — marks a turning point in market dynamics. Rather than acting as short-term profit-takers, miners are increasingly functioning as long-term stewards of supply.
With only 150 BTC sold by Satoshi-era miners in 2025 versus nearly 10,000 BTC in 2024, and large operators adding thousands of BTC to reserves despite falling revenues, the narrative is clear: confidence outweighs immediate financial need.
This shift not only supports ongoing price momentum but also reflects greater sophistication within the mining ecosystem. As Bitcoin continues to mature as both an asset and network, such on-chain signals offer invaluable insight into market psychology and potential future direction.
For investors and observers alike, monitoring miner behavior remains a critical component of understanding macro trends — and right now, the message from the mines is simple: hold.
