Bitmine Buys More ETH, Strategy Posts $17B Loss—What’s the Difference?

Bitmine Immersion Technologies (BMNR) announced Monday that its Ethereum holdings have reached 4.14 million ETH, valued at approximately $13.2 billion. The company now owns 3.43% of the total Ethereum supply, with 779,000 ETH already generating staking yield.

The aggressive accumulation contrasts sharply with Strategy Inc. (MSTR), which disclosed a $17.44 billion unrealized loss in the fourth quarter on the same day.

Bitmine Bets On Staking Yield

Bitmine Chairman Tom Lee said the company acquired 32,977 ETH in the final week of 2025, maintaining its status as the largest “fresh money” buyer of Ethereum globally. The company aims to accumulate 5% of the total supply, a target Lee calls the “Alchemy of 5%.”

“We are excited about the prospects for Ethereum in 2026 given the multiple tailwinds of US government support for crypto, Wall Street embracing stablecoins and tokenization,” Lee said.

Meanwhile, Onchain Lens data showed that Bitmine staked an additional 186,336 ETH, worth $604 million, bringing total staked holdings to 779,488 ETH, valued at $2.52 billion.

Bitmine’s staking strategy addresses a core weakness of digital asset treasuries. Crypto holdings generate no income, while companies must service debt and pay dividends. The company plans to launch its Made in America Validator Network (MAVAN) in Q1 2026. At full deployment, Bitmine projects annual staking revenue of $374 million—over $1 million daily.

Strategy’s Losing Streak Deepens

Strategy, the pioneering Bitcoin treasury company led by Michael Saylor, faces mounting pressure. Its stock tumbled 48% in 2025, plunging nearly 70% from the November 2024 peak. The company posted $17.44 billion in unrealized losses in the fourth quarter alone. The full-year 2025 figure came in at $5.4 billion—far smaller because gains earlier in the year partially offset the Q4 collapse.

Its stock tumbled 48% in 2025, plunging nearly 70% from the November 2024 peak. The company’s mNAV—the ratio of market cap plus debt to token holdings—has fallen to just above 1, eroding the premium investors once paid for leveraged Bitcoin exposure. Strategy established a $2.25 billion cash reserve in December to address concerns about servicing obligations, but it generates no yield from its 673,783 Bitcoin, which are worth approximately $63 billion.

Two Models, One Question

Both companies remain exposed to crypto volatility, but their diverging approaches—yield-generating staking versus pure price appreciation—may determine which treasury model proves sustainable as institutional adoption accelerates.
