Enterprise Bitcoin and Ethereum Treasury Panorama: Strategy, Bitmine, and Mining Company Holdings Strategy Explanation

In Q1 2026, Bitcoin’s price, which had fallen steadily from a peak above $110,000 in mid-2025 to below $70,000, put corporate Bitcoin treasury strategies through a collective stress test. About 40% of publicly traded Bitcoin treasury companies traded at prices below their net asset value, and the financing—buy-and-rollover—cycle that the market once dubbed an “infinite money loophole” was failing.

Against this backdrop, three types of corporate holders exhibited distinctly different behavioral patterns and financial outcomes: aggressive, leverage-accumulation holders represented by Strategy were still continuously buying; yield-staking holders represented by Bitmine sustained operations through asset productivity; and miners represented by Marathon and Riot accelerated Bitcoin selling, shifting toward AI infrastructure or debt management. Each of the three models reflects a different capital structure, risk appetite, and sustainability logic.

Based on publicly available data as of April 7, 2026, this article compares and analyzes the core differences between the Bitcoin treasury strategies of these three types of enterprises, and extrapolates their long-term evolution directions under multiple scenarios.

At the limit of aggressive leverage: How long can Strategy’s “Saylor-style buying” last?

Strategy (formerly MicroStrategy) is the largest corporate Bitcoin holder in the world. As of April 6, 2026, Strategy held 766,970 BTC, with a cumulative invested cost of approximately $58.02 billion and an average cost basis of $75,644 per coin.

• Between March 30, 2026 and April 5, 2026, Strategy raised $330 million through preferred stock issuance of STRC and raised $144 million through common stock issuance of MSTR, for total proceeds of $474 million. It bought 4,871 BTC at an average price of $67,718. As of now, Strategy still has roughly $27.0 billion worth of remaining issuance capacity for MSTR shares that it can use.
• In Q1 2026, Strategy recognized $14.46 billion in unrealized digital asset losses. As of March 31, its digital asset carrying value was $51.65 billion, and deferred tax assets were $2.42 billion, but it also recorded valuation allowances of an equal amount at the same time.

Strategy’s “21/21 plan”—raising $21 billion each through equity financing and fixed-income instruments—essentially converts equity market premium into financial engineering for Bitcoin holdings. Its sustainability depends heavily on two conditions: the equity market prices MSTR stock at a premium (mNAV > 1), and Bitcoin’s price does not remain below its average cost basis over the long term.

Both conditions are weakening now. Strategy’s mNAV is nearing 1x, meaning the market is no longer willing to pay a premium for MSTR relative to the value of the Bitcoin it holds. The company is increasingly relying on preferred stock financing; STRC’s annualized dividend rate is already as high as 11.5%. The company holds about $2.25 billion in cash reserves, sufficient to cover interest and dividend payments for more than two years, but this defensive window is narrowing.

If mNAV remains below 1x for the long term, the appeal of raising new funds through share issuance will drop sharply. At that point, Strategy may face two choices: continue financing with preferred stock at even higher cost (further driving up fixed expenditures), or slow the pace of buying. Based on its current cash reserves and financing costs, Strategy can still sustain continuous purchases for 12 to 18 months without relying on stock-price premium—but its leverage capacity is being compressed.

A buffer from staking yields: Bitmine’s Ethereum treasury defense model

Bitmine Immersion Technologies chose a path sharply different from Strategy. It positions itself as the “largest Ethereum treasury company in the world.” As of April 5, 2026, it holds about 5.72T ETH, representing 3.98% of ETH’s circulating supply. Of this, more than 4.8M ETH have been staked via the MAVAN platform; the staked assets are valued at approximately $7.1 billion (at $2,123 per ETH), and the current annualized staking yield is about $196 million.

• Bitmine is continuously accelerating its Ethereum buying. In the week ending April 5, the company added 71,252 ETH, setting the highest single-week record since December 2025. Tom Lee, Chairman of Bitmine’s board, said the accelerated buying was based on the view that Ethereum is in the final phase of a “mini crypto winter.”
• Bitmine also faces pressure from unrealized losses on its books. Since the average cost basis for ETH is about $2,123, and as of April 7, 2026 the ETH price is $2,111.41, the scale of mark-to-market unrealized losses on paper is relatively limited. But in late February 2026, when the ETH price dipped into lower ranges, the company experienced unrealized losses exceeding $8.4 billion.

The core defensive mechanism in Bitmine’s model is “staking yield.” Even if Ethereum trades in a range around $3,000, Bitmine can still earn about $590 million in staking income each year. This cash flow can cover part of operating costs and, when capital markets tighten, provide a continuing source of liquidity. Unlike Strategy, which relies entirely on external financing, Bitmine’s holdings themselves have “production capacity.”

Bitmine’s sustainability depends highly on Ethereum’s staking yield and the long-term trend in Ethereum’s price. If Ethereum’s price falls further, the fiat value of staking yields will be compressed; if staking yields decline due to network upgrades or intensified competition, the cash-flow defense function will also weaken. But compared with pure leverage accumulation, Bitmine has more ample buffer space in a bear market—staking yields can partially offset the mark-to-market losses caused by falling prices.

From “diamond hands” to strategic deleveraging: miners’ shifting logic for Bitcoin holdings

Miners are the third major category of corporate Bitcoin holders, but their behavior changed significantly in Q1 2026. Seven leading U.S. and Canadian publicly traded mining companies held Bitcoin worth approximately $2.79 billion.

• Marathon Digital Holdings sold 15,133 BTC between March 4, 2026 and March 25, 2026, raising about $1.1 billion. It used the proceeds to repurchase approximately $1.0 billion of convertible bonds, reducing its total outstanding debt by about 30%. After the sale, MARA’s Bitcoin holdings fell from 53,822 BTC at the start of the year to 38,689 BTC.
• Riot Platforms also accelerated its selling. Its Bitcoin holdings fell from 19,368 BTC at the end of 2025 to about 18,000 BTC in January 2026, a reduction of more than 1,300 BTC. On April 2, 2026, Riot transferred an additional 500 BTC again, which the market widely interpreted as being prepared for sale.
• Metaplanet became an exception. This Japanese listed company spent about $398 million in Q1 2026 to buy 5,075 BTC, bringing its total holdings to 40,177 BTC—surpassing MARA to become the world’s third-largest publicly traded Bitcoin holder.

Miners’ selling behavior reflects constraints from their specific business model. Mining companies’ operating costs (electricity, equipment depreciation, labor) must be paid in fiat currency, while Bitcoin block rewards being halved and competition for hash power across the network continue to compress mining profit margins. When the Bitcoin price falls below mining costs or when market financing costs rise, miners sell holdings to pay operating expenses or repay debt—this is a rational financial decision rather than a “collapse of conviction.”

Riot sold Bitcoin to support a transition toward AI and high-performance computing infrastructure, while Marathon sold to reduce debt leverage. Together, these moves indicate that miners are treating Bitcoin holdings as reallocatable liquidity assets rather than untouchable strategic reserves.

Sustainability comparison across the three models

The table below compares the three types of corporate Bitcoin treasury strategies across four dimensions: financing structure, cash-flow sources, stress resilience, and core risks.

• In Q1 2026, about 40% of publicly traded Bitcoin treasury companies traded at prices below their net asset value, indicating that the market is questioning the effectiveness of passive holding models. Strategy’s mNAV has fallen to about 0.94x, meaning its stock trades at roughly a 6% discount to the per-share Bitcoin value it supports.
• Strategy currently holds about 76% of all corporate treasury Bitcoin. Recently, its digital-asset treasury purchase share surged to about 98%. Meanwhile, all other companies combined purchased only about 1,000 BTC during the same period, down 99% from peak activity.

Corporate Bitcoin treasuries are shifting from “distributed accumulation” to “concentrated risk.” The market currently depends heavily on the ability of a single company (Strategy) to keep buying. If Strategy’s financing channels further narrow or if mNAV stays below 1x, the entire corporate Bitcoin buying narrative could face a structural interruption.

Market narrative vs. real pressure: the boundary of the “diamond hands” myth

For a long time, the market narrative for corporate Bitcoin treasuries has centered on “institutionalization.” The logic was that when public companies put Bitcoin on their balance sheets, Bitcoin shifts from being led by retail investors to becoming a standard option for institutional allocation. This narrative helped drive corporate Bitcoin purchasing booms in 2024 and 2025.

But the price pullback in Q1 2026 exposed the structural limits of this narrative:

• During the summer 2025 peak, many digital asset treasury companies saw their market capitalization briefly spike to 3 to 5 times net asset value. Those premiums have largely disappeared now; some companies even trade at a discount.
• The total Bitcoin holdings by listed companies still exceed 1.16 million BTC, representing more than 5% of total supply. But over the past week, the total number of BTC held by listed companies fell from about 1.07 million to about 1.06 million, for net selling of roughly 10k BTC.
• The large-holder cohort holding 1,000 to 10,000 BTC has turned into net sellers. Their position increase shifted from about +200k BTC at the high point of the 2024 bull market to roughly -188k BTC today.

The behavior of corporate Bitcoin holders is shifting from “one-way accumulation” to “two-way management.” When Bitcoin enters a down cycle, corporations will also sell holdings to meet needs such as debt management, operating financing, or strategic transformation. This means that “institutionalization” is not inherently a volatility-smoothing mechanism. If institutional behavior resembles a cyclical liquidity manager rather than a perpetual holder, institutions could actually amplify two-way market volatility.

Scenario-based evolution projections

Based on the current financing structure, price level, and corporate behavioral patterns, over the next 12 to 18 months, corporate Bitcoin treasury models may follow one of three possible evolution paths:

Scenario 1: Bitcoin rebounds to above $85,000

• If Bitcoin rises back above $85,000, Strategy’s unrealized losses could narrow significantly, and mNAV has the potential to expand again. Capital markets would likely re-recognize the value of its “Bitcoin leverage,” lowering equity financing costs and allowing Strategy to continue its accumulation model. Bitmine’s staking-yield value would also increase as Ethereum’s price rebounds. Miners might slow their selling pace and even restart accumulation.

Scenario 2: Bitcoin trades sideways between $60,000 and $75,000

• This is the most likely scenario. Within this range, Strategy continues to face unrealized loss pressure, making it difficult for mNAV to return to a significant premium. The company would rely more on high-cost financing such as preferred stock; the 11.5% annualized dividend burden would gradually erode its cash reserves. Bitmine’s staking yield can maintain operations, but it cannot support large-scale accumulation. Miners would continue to choose selective selling to manage debt and cash flow, and corporate Bitcoin purchases would concentrate among a few participants with special financing channels.

Scenario 3: Bitcoin falls below $60,000

• If Bitcoin drops below $60,000, Strategy’s unrealized losses would widen further, deepening the mNAV discount. Some companies using leverage models may face forced liquidation risk. Debt pressure at high-leverage treasury companies would intensify, potentially triggering chain reactions similar to a Nakamoto-style collapse. Under this scenario, the corporate Bitcoin narrative would shift from an “accumulation race” to a “survival race,” and proactive balance-sheet management would become the norm.

Regardless of which scenario occurs, the structural divergence among corporate Bitcoin treasury models will continue. The purely “buy and hold” passive strategy is being replaced by three more complex patterns: capital-engineering-based accumulation (Strategy), asset-yield-based allocation (Bitmine), and liquidity-management-based holding (miners). Differences in sustainability across models will be ultimately tested in the next full market cycle.

Conclusion

Strategy, Bitmine, and miners each represent three prototypes of corporate Bitcoin treasuries: leverage accumulation, staking-yield generation, and operational hedging. Strategy—with a BTC holding size of 767k and a quarterly unrealized loss of $14.5 billion—demonstrates the scale effect and fragility of aggressive leverage. Bitmine—with nearly $600 million in annualized staking yield—shows that digital assets themselves can become productive capital. Miners’ collective selling reveals an easily overlooked fact: corporate Bitcoin holders are also constrained by cash-flow needs and debt cycles.

In a market environment where around 40% of Bitcoin treasury companies trade at a discount and the large-holder cohort has turned into net sellers, the corporate Bitcoin narrative is shifting from “belief-driven” to “finance-driven.” Which model is the most sustainable? The answer does not depend on long-term Bitcoin price predictions, but on whether each model can cross a full market cycle without being forced to sell under its underlying business-logic and capital-structure constraints.
