Ethereum Crash Pushes BitMine into $3.7B Unrealized Loss

BitMine Immersion Technologies, the largest corporate holder of Ethereum, is now facing an estimated $3.7 billion unrealized loss on its reserves. 

The scale of this setback has intensified scrutiny of digital-asset treasury firms, many of which depend on rising crypto prices to support their business models.

BitMine Ethereum Cost Basis Exposes the Depth of the Decline

The latest 10x Research report shows that the company is down roughly $1,000 per ETH, with its 3.56 million coins, worth approximately $10.7 billion, purchased at an average of $4,051 each, well above the current market price of $2,789.

This comes as Ethereum has dropped 8% in the past 24 hours alone. Specifically, the decline widened the gap and added pressure to BitMine’s balance sheet while straining investors seeking liquidity.

According to 10x Research CEO Markus Thielen, these losses are making it harder for shareholders to exit positions without accepting steep discounts. He said shrinking premiums across digital-asset treasuries leave many investors effectively “stuck,” especially as valuations continue to compress.

mNAV Decline Highlights Limited Capital Options

BitMine’s position becomes clearer when viewed through its modified net asset value (mNAV). This ratio compares the company’s market valuation with the net value of its crypto holdings.

Specifically, a reading above 1 signals that a firm trades at a premium, allowing it to raise capital by issuing new shares. Conversely, a reading below 1 suggests a discount, making share issuance far less attractive.

BitMine’s basic mNAV is 0.75, while its diluted mNAV stands at 0.92, according to Bitminetracker. Both figures remain below parity, indicating that the market values the company at less than its underlying assets. Consequently, BitMine has limited flexibility to expand its holdings or raise funds through equity.

Similarly, several other digital-asset treasury firms, including Strategy, Metaplanet, Sharplink Gaming, Upexi, and DeFi Development Corp, have also seen their mNAVs fall. This trend suggests that the pressure on BitMine is part of a wider industry strain rather than an isolated case.

These financial pressures come alongside deeper issues. According to 10x Research, many digital-asset treasury firms use complex, opaque fee systems similar to hedge funds. Thielen warns that such structures can gradually reduce returns, especially in weak markets with lower liquidity.

BlackRock’s New ETF Adds Competitive Pressure

Meanwhile, the environment is becoming increasingly challenging as BlackRock expands its Ethereum product. The firm recently registered a staked Ethereum ETF in Delaware, signaling a big push into yield-generating crypto offerings.

10x Research suggests this could draw investors toward simpler, more transparent options. BlackRock’s ETF has a 0.25% management fee, much lower than the costs built into traditional digital-asset treasuries.

With REX-Osprey and Grayscale already launching similar staked ETH ETFs earlier this year, competition is heating up fast.

Overall, BitMine and similar firms face a tough environment. Falling mNAVs, large unrealized losses, and the growth of low-cost crypto ETFs are reshaping the market.
