Tom Lee–Linked Bitmine Sits on $6B in Unrealized Losses on ETH Reserve

Bitmine Immersion Technologies, a publicly traded digital asset treasury firm linked to investor Tom Lee, is facing more than $6 billion in unrealized losses on its Ether reserves after the latest downturn in crypto markets, highlighting the balance-sheet risks tied to large-scale token accumulation strategies.

The losses widened after Bitmine acquired an additional 40,302 Ether last week, lifting its total holdings to over 4.24 million ETH.

Data from Dropstab shows the firm’s Ether position is now valued at roughly $9.6 billion at current prices, down sharply from an estimated peak of $13.9 billion in October.

Thin Liquidity and Leverage Pressure Push Ether Toward $2,300

The drawdown comes amid a broader market sell-off that has weighed heavily on major digital assets.

Ether prices slid toward the $2,300 level over the weekend, a move that market observers linked to thinning liquidity and elevated leverage.

Analysts at The Kobeissi Letter said fragile market depth left prices vulnerable to sudden gaps lower, with crowded positioning accelerating the decline once selling pressure emerged.

The result has been a swift erosion of paper gains for firms holding large, concentrated crypto reserves.

The setback marks a sharp contrast from the optimism that surrounded crypto markets earlier in the cycle.

Lee, who has been a long-time advocate of digital assets, has recently cautioned that near-term conditions have deteriorated.

He warned that 2026 could begin on a difficult footing as markets continue to digest the effects of deleveraging that followed October’s $19 billion liquidation event, which reset risk appetite across the sector.

Despite the losses, Lee has maintained that longer-term fundamentals for crypto remain intact, arguing that the current phase represents a painful adjustment rather than a structural breakdown.

2026 is shaping up to be similar to 2025:

– good fundamentals 😀
– tariff escalations and White House picking “winners and losers”
– political divisiveness
– tailwinds from AI and blockchain
BUT: dovish Fed now and QT over

And so a painful decline may lie ahead but we would… https://t.co/7Mp3rcOcP1

That view was echoed in a recent market outlook from Wintermute, which said a durable recovery will require renewed momentum in Bitcoin and Ether, broader participation from exchange-traded funds and expanded corporate treasury adoption.

Wintermute also pointed to the absence of retail inflows as a key constraint. With many investors drawn to faster-growing themes such as artificial intelligence and quantum computing, crypto markets may struggle to regain their previous wealth effect until confidence and liquidity return.

Ethereum Foundation Makes Quantum-Resistant Security a Strategic Priority

As reported, the Ethereum Foundation has elevated post-quantum security to a core strategic focus, forming a dedicated Post Quantum team and committing $2 million to the effort.

Announced by Ethereum researcher Justin Drake, the initiative will be led by Thomas Coratger alongside Emile, a contributor to leanVM.

Drake said the foundation has been working on quantum-resilience research quietly for years, dating back to early discussions in 2019, before formally making it a top-level priority.

The foundation’s plan spans research, development, and ecosystem coordination.

This includes new developer calls focused on user-facing security, two $1 million cryptography prize programs, active multi-client post-quantum testing networks, and a series of global workshops aimed at accelerating collaboration and readiness across the Ethereum ecosystem.
