BroadChain has learned that on March 6, professional short-selling research firm Culper Research announced it is taking a short position on Ethereum (ETH) and related securities, with a primary focus on Nasdaq-listed company BitMine Inc. (ticker: BMNR).
Based on extensive industry analysis and data verification, Culper Research concludes that the Digital Asset Treasury (DAT) model—which relies on fundraising to inflate the value of token holdings—has largely run its course. Assets tied to the Ethereum ecosystem are collectively facing a severe valuation bubble, with significant downside pressure building.
I. Core Short Thesis: BitMine’s Business Model Is Unsustainable—Its Growth Is “Artificial”
Culper Research’s analysis of BitMine’s core business model reveals that its growth is not driven by genuine profitability, but by a “circular game” dependent on continuous fundraising to prop up its valuation.
The mechanism works as follows: issue shares to raise capital → use the proceeds to buy large amounts of Ethereum (ETH) → artificially boost the ETH holdings per share → thereby supporting an inflated stock price. This creates a closed loop of “fundraise → buy tokens → boost valuation.”
This model lacks a foundation of sustainable earnings. Once funding dries up or market sentiment shifts, the valuation bubble is poised to burst.
II. Severe Valuation Overextension: Trading at a Premium Disconnected from Fundamentals
Globally, digital asset treasury companies using the DAT model have generally seen their share prices fall below net asset value (NAV), with NAV premiums evaporating across the board—a sign the industry is returning to rational valuations.
Yet BitMine’s stock still trades at roughly a 1.4x premium to its NAV, well above the industry average. This highlights a severe disconnect from fundamentals and clear room for a valuation correction.
III. Delayed Disclosure: Withholding Key Data to Obscure Deteriorating Fundamentals
Culper Research notes that BitMine has recently stopped reporting several core operational metrics in a timely manner, seemingly to avoid market scrutiny. The undisclosed data includes:
• NAV per share denominated in ETH (a key valuation anchor);
• The number and timing of new share issuances (which directly dilute ETH holdings per share);
• Total ETH holdings and changes (reflecting asset quality and valuation support).
Culper Research believes this opacity is intended to conceal the ongoing dilution of ETH-per-share and declining asset quality—thereby masking flaws in the company’s valuation narrative.
IV. Clear Downside Risk: BMNR Could Fall >40% Even If ETH Price Stays Flat
Culper Research provides a concrete valuation assessment: even assuming Ethereum’s price remains stable, simply aligning BitMine’s share price with the industry’s rational premium level (i.e., trading at NAV) would imply a downside of over 40%—underscoring pronounced correction pressure.
V. Broader Pressure on Ethereum: Three Key Factors Weighing on the Asset
Beyond BitMine’s specific issues, Culper Research notes that Ethereum itself faces growing headwinds, raising the risk of a medium-term correction. Three core factors are at play:
1. Slowing institutional inflows: Inflows into Ethereum spot ETFs have peaked in the near term, with insufficient new capital to sustain current elevated valuations.
2. Weak fundamental support: Key on-chain metrics—including network utilization, on-chain revenue, and ETH fee burn—do not justify Ethereum’s current price, creating a severe mismatch between valuation and fundamentals.
3. Macro and regulatory pressure: Persistently high global interest rates and elevated funding costs continue to weigh on risk assets. Meanwhile, unresolved regulatory uncertainty in the crypto sector is further dampening market sentiment.
VI. Key Conclusions
• The core “token-holding appreciation” thesis behind the Digital Asset Treasury (DAT) model is breaking down, and the industry is entering a valuation normalization cycle.
• Ethereum, pressured by capital flows, fundamentals, and regulation, may be entering a medium-term correction phase with substantial downside risk.
• ETH-linked assets like BitMine (BMNR)—burdened by an unsustainable model, overvaluation, and opaque disclosures—face significant catch-down risk, with clearly defined downside potential.
