Bitmine Increases Ethereum Holdings, Faces Strategy Inc’s $17 Billion Loss

Bitmine Immersion Technologies (BMNR) reported on Monday an increase in its Ethereum holdings, now totaling 4.14 million ETH, valued at about $13.2 billion. This accounts for approximately 3.43% of Ethereum’s total supply, with 779,000 ETH already being used to generate staking yields. This strategic accumulation stands in contrast to Strategy Inc. (MSTR), which, on the same day, revealed a $17.44 billion unrealized loss for the fourth quarter.

Bitmine’s Focus on Ethereum Staking

Tom Lee, Chairman of Bitmine, stated that the company acquired 32,977 ETH in the final week of 2025, solidifying its position as the largest global purchaser of Ethereum with new capital. Bitmine’s goal is to acquire 5% of Ethereum’s total supply, a strategy Lee refers to as the “Alchemy of 5%.”

“We are optimistic about Ethereum’s prospects in 2026, given the favorable conditions such as U.S. government support for cryptocurrencies and Wall Street’s acceptance of stablecoins and tokenization,” Lee remarked. Additionally, Onchain Lens data reveals that Bitmine has staked an extra 186,336 ETH, valued at $604 million. This brings its total staked holdings to 779,488 ETH, approximately $2.52 billion in value.

Bitmine’s approach aims to address a key challenge facing digital asset treasuries: the lack of income generation from holdings, while companies still need to service debt and pay dividends. The company plans to introduce its Made in America Validator Network (MAVAN) in the first quarter of 2026, with full deployment expected to generate an annual staking revenue of $374 million, or just over $1 million per day.

Strategy Inc’s Declining Performance

Strategy Inc., known for its pioneering role in Bitcoin treasury management under the leadership of Michael Saylor, is facing significant pressure. In 2025, the company’s stock plummeted by 48%, marking a nearly 70% decrease from its peak in November 2024. The fourth quarter alone saw unrealized losses amounting to $17.44 billion, although the full-year loss was $5.4 billion due to earlier gains.

The company’s market value-to-asset ratio (mNAV) has dropped to just over 1, diminishing the premium investors once paid for its leveraged Bitcoin exposure. To address concerns over meeting financial obligations, Strategy Inc. set aside a $2.25 billion cash reserve in December. However, its 673,783 Bitcoin holdings, worth roughly $63 billion, do not generate any yield.

Evaluating Two Treasury Models

Both Bitmine and Strategy Inc. are vulnerable to the inherent volatility in the crypto market. However, their differing strategies—Bitmine’s yield-generating staking versus Strategy’s reliance on price appreciation—could determine which model sustains as institutional interest in cryptocurrencies grows. The outcome of these strategies remains to be seen as the market continues to evolve.
