Miner Treasury Liquidation Accelerates as Economics Turn Negative: The $15B Question for Bitcoin Supply
Bitcoin miners have shifted from long-term holders to forced sellers over the past five months, liquidating more than 15,000 BTC while facing mining economics below breakeven levels[1][3]. This reversal-from a cohort that once championed “never sell” policies to one now executing systematic treasury drawdowns-reflects not market timing but structural margin compression. The data reveals an uncomfortable pattern: as Bitcoin’s price declined from above $110,000 in October 2025 to approximately $70,000 by February 2026, public miner sales accelerated rather than contracted, signaling not confidence but operational desperation[1].
Key Takeaways
• Margin Compression Driver: February 2026 miner sales reached 6,100 BTC, the largest single-month volume in five months, as hashprice fell below $30/PH/s-below total cash costs for most public miners[1][3].

• Treasury Policy Reversal: Marathon Digital (MARA) expanded 2026 bitcoin sales beyond newly mined production after holding 53,822 BTC; Core Scientific plans to liquidate substantially all holdings in Q1 2026[2].
• Structural Forced Selling: Public miners sold 15,000+ BTC since October 2025 with 90,000 BTC transferred to Binance in February 2025 alone, creating measurable sell-side pressure independent of market sentiment[1][4].
• Profitability Crisis Timing: Miner profit/loss sustainability index hit 14-month low at 21 in January 2026, with miners facing up to $19,000 per BTC losses as electricity and financing costs remain fixed while revenue crashes[6][7].
• Liquidity Event Risk: Multiple miners citing “may necessitate greater volume sales” for working capital suggests reactive rather than planned liquidations, concentrating selling pressure during downturns when absorption capacity weakens[3].
The Mechanics of Forced Liquidation
The five-month selling period from October 2025 through February 2026 reveals a critical distinction: this was not discretionary accumulation or market-timing activity. Public bitcoin miners operate under structural constraints that fundamentally differ from traditional long-term holders. Revenue is directly tied to bitcoin’s market price and network difficulty, while operating costs-electricity, infrastructure, financing, and staffing-remain fixed or rising regardless of profitability[2].
When hashprice (revenue per unit of hash rate) falls below marginal cash costs, miners face an immediate liquidity squeeze. As of January 2026, the miner profit/loss sustainability index reached 21, its lowest level since November 2024[6]. For context, this metric measures the relationship between Bitcoin’s price and mining profitability; at this level, miners are operationally underwater. Some miners face up to $19,000 losses per BTC mined, forcing them to tap existing treasury reserves rather than hold newly produced supply[7].
The selling pattern across the five-month window demonstrates this mechanical pressure:
October and November 2025 saw modest sales of approximately 1,300 and 1,500 BTC respectively, when Bitcoin traded above $90,000[1]. December 2025 jumped sharply to 3,100 BTC as prices moved lower, with Riot liquidating four times its monthly production[3]. January 2026 reached 3,600 BTC, while February 2026 exploded to 6,100 BTC as prices fell toward $70,000[1].
This acceleration-not deceleration-as prices fell is the inverse of typical holder behavior. Long-term accumulators typically buy more aggressively on weakness; miners must sell more aggressively on weakness to cover operational losses and maintain liquidity for ongoing operations[1].
Treasury Policy Shifts: From HODLing to Survival Mode
The 2025 earnings disclosures released in March 2026 reveal a systemic policy reversal across the largest public mining operators. Marathon Digital Holdings (MARA), which held 53,822 BTC valued at approximately $4.7 billion as of December 31, 2025, disclosed that it expanded its crypto management strategy for 2026 to permit sales of bitcoin held on its balance sheet[2]. This marks a significant departure from the company’s 2025 policy, which allowed sales only from newly mined production.
The shift reflects deteriorating mining economics. MARA mined 8,799 BTC in 2025, down from 9,430 in 2024, a direct impact of the April 2024 halving and rising network difficulty[2]. At the same time, the company recorded a $422.2 million decrease in fair value of its holdings as bitcoin prices fluctuated through 2025[2]. Large BTC treasuries amplify gains during bull markets but magnify balance sheet pressure during downturns-a dynamic that has clearly shifted MARA’s calculus.
Core Scientific’s announcement was more dramatic. In its latest annual report released in early March 2026, the company revealed plans to sell substantially all of its roughly 2,500 BTC holdings in the first quarter, with 1,900 BTC already sold in January for approximately $175 million[2][3]. This represents a complete treasury liquidation program tied explicitly to a strategic pivot toward AI and high-density colocation services, but the timing-executing during a price downturn-suggests operational liquidity needs drove the schedule[2][3].
Riot, another major operator, noted in filings that bitcoin’s downward trend “may necessitate the sale of a greater volume” of its bitcoin than previously anticipated to maintain liquidity for ongoing operations[3]. The language “may necessitate” reveals reactive decision-making rather than strategic planning. These are not trades; they are survival mechanisms.
On-Chain Flow Asymmetry and Liquidity Dynamics
The aggregate flow data illuminates the immediate market structure implications. On-chain data reveals that 90,000 BTC transferred from mining entities to the Binance exchange in February 2025 alone, the largest monthly volume since early 2024[4]. This represents not just selling pressure but also a concentrated liquidity event on one exchange, raising questions about the market’s absorption capacity and whether such supply concentration narrows the bid-ask spread or triggers cascading selling mechanics.
To contextualize: the Bitcoin network currently produces approximately 900 BTC per day[4]. The 6,100 BTC sold by public miners in February 2026 alone represents approximately 6.8 days of total network production concentrated into a single month and likely concentrated across fewer trading days. This creates a temporary but material oversupply to the market’s daily absorption baseline.
The critical insight is not the absolute volume-90,000 BTC is roughly 0.45% of Bitcoin’s circulating supply-but the concentration and timing. Miners are structurally forced to sell during downturns, when market liquidity is typically tightest and speculative demand is weakest. This creates an asymmetry: during bull markets, miners hold; during bear markets, miners dump. This is the inverse of what would create stable price action.
The flow concentration also matters for spot market dynamics. When selling is concentrated in a single venue and a short timeframe, it can trigger cascade effects if bids are thin. Conversely, if the market successfully absorbs 90,000 BTC inflows without triggering further liquidation cascades, it suggests underlying demand resilience despite the miner supply shock.
Revenue Collapse and Operating Cost Pressure
The profitability metrics reveal the economic trap. Hashprice is the key profitability metric for miners: revenue per unit of computational power (measured in dollars per petahash per second, or $/PH/s). Recent data shows hashprice falling below $30/PH/s, a level below the total cash-based hashcost for most public miners[3]. This means that for many operators, the marginal revenue from mining a new block no longer covers the direct cash cost of electricity and equipment maintenance.
This is distinct from GAAP profitability-which can remain positive due to depreciation and financing structures-but it directly impacts cash flow. When hashprice falls below cash costs, miners cannot sustainably operate without drawing on reserves or raising external capital[3]. The January 2026 sustainability index at 21 confirms this: at that profitability level, miners are mining at a loss in real-time cash terms.
Operating costs compound the problem. Electricity costs remain largely fixed under long-term power purchase agreements (PPAs), many locked in at high rates during the 2021-2024 bull market. Financing costs rise as collateral values decline and credit conditions tighten. Infrastructure, hosting, and staffing remain fixed overhead. Revenue, by contrast, moves directly with Bitcoin’s price and difficulty-both of which moved sharply against miners in early 2026[6].
This creates a time-bound problem: miners cannot indefinitely sustain negative hashprice. They either raise external capital, negotiate better power deals, or liquidate reserves. Given the current market environment, external capital is expensive and difficult to access. Power deals are long-term and cannot be renegotiated quickly. Treasury liquidation is the immediate lever[2][3].
Strategic Positioning Implications
For traders and institutional investors, the miner liquidation creates a specific structural imbalance: forced supply into a demand curve that is weakening rather than strengthening. This is the opposite of the 2024 halving dynamic, when miner supply was cut in half while demand surged on ETF inflows and macro optimism.
The current environment shows large miners becoming net sellers precisely when smaller retail holders, according to CryptoQuant LTH (long-term holder) data referenced in sources, are accumulating[1]. This creates a positioning divergence: the largest and most leveraged holders of newly produced supply are reducing exposure while smaller, less-leveraged holders are increasing it. This suggests a potential redistribution of supply from forced sellers to patient accumulators-a dynamic that typically precedes supply-demand rebalancing.
However, the timing of this rebalancing matters critically. If miner selling continues to accelerate faster than new demand emerges, the selling pressure could extend, keeping prices compressed until miner profitability improves or miner balance sheets are substantially reduced. Conversely, if new demand (from institutional buyers, geopolitical demand, or macro catalysts) absorbs the miner supply without triggering further cascades, the liquidation could represent a supply shock that clears quickly rather than one that creates persistent downside pressure.
Forward-Looking Structural Risk
The most material risk embedded in current miner dynamics is reactive rather than planned liquidation. Marathon and Core Scientific have disclosed specific timelines and quantities; this is transparent and likely already priced. But other miners cited “may necessitate” language, suggesting threshold-triggered selling rather than predetermined schedules[3]. If Bitcoin’s price extends lower from current levels, additional forced selling could accelerate, creating a potential cascade dynamic where each wave of liquidations pressures prices further, triggering additional margin calls or operational crises at the next tier of mining operators.
This risk is asymmetric: if mining economics improve (via price recovery or difficulty adjustment), the selling pressure ends and can reverse. If economics deteriorate further, the feedback loop intensifies. The sustainability index at 21 has room to fall further before reaching true economic breakeven, suggesting that downside risk in forced selling remains material.
The shift in miner treasury policy also has longer-term implications for Bitcoin’s supply dynamics. If large miners transition from “never sell” to “sell strategically” policies, the narrative of miners as long-term accumulators and supply reducers effectively ends. They become traders and operational entities rather than treasury operators. This changes the supply/demand calculus for the Bitcoin market and removes one structural element that previously supported price floors during downturns.
Market Structure Verdict
The data shows miner selling accelerating from 15,000 BTC over five months (October 2025-February 2026) with February alone accounting for the largest single-month volume. This represents measurable, concentrated sell-side pressure at a time when mining economics are at 14-month lows and miners face up to $19,000 per BTC losses. The treasury policy reversals from Marathon and the announced liquidation from Core Scientific provide transparency into the magnitude of potential supply, but the reactive language from other miners suggests additional selling could emerge if conditions deteriorate.
For positioning purposes, this creates a structural supply headwind that is independent of market sentiment or retail investor behavior. The offset-patient accumulation by smaller holders and potential institutional demand-is not yet visible in flow data at a scale that clearly overwhelms the miner supply. Until that dynamic shifts, miner liquidation remains a material risk to price stability, and the absorption of additional supply remains the key test for market structure resilience.
