Culper Research Short Selling ETH Event Overview

The short-selling institution Culper Research publicly disclosed a short position on ETH, while also shorting related assets BMNR, and released a short report.

1. Core Logic of Short Selling

1. Fusaka Upgrade Aftermath
The increase in Gas limit led to approximately 90% drop in Gas fees, reducing validator staking rewards and weakening network incentives.
2. On-Chain Data Falsification
About 95% of new wallets are dust attacks, over 50% of transaction growth is due to false address poisoning, and genuine demand is severely exaggerated.
3. Competition Pressure
L1 market share is being continuously eroded by Solana and various L2 solutions, with ecosystem value spilling over.
4. Key Figures’ Dispositions
The report mentions that Vitalik Buterin sold nearly 20,000 ETH within the year, supporting a bearish stance.

2. Market Impact

Short-term (1–3 days)
- Sentiment turns bearish, ETH prone to sharp drops and wide fluctuations
- Triggers stop-losses/position reductions, amplifying volatility
- Short-selling sentiment spreads, dragging down ETH-based L2 and DeFi

Medium-term (1–2 weeks)
- Tests key support levels; breaking below may trigger negative feedback
- Movements of institutions and whales will determine whether sentiment is digested or trend weakens
- Related stocks BMNR face pressure

Long-term
- Does not alter the fundamental outlook of the Ethereum ecosystem, but will push for protocol optimization, burning mechanisms, and faster L2 deployment
- If on-chain data recovers later, the short thesis will be invalidated

3. Operational Reminders

- Short-term: Strictly control leverage, implement proper take-profit and stop-loss strategies
- Long-term: Focus on core data such as Gas, staking yields, and active addresses for validation
- Caution: Short reports often exaggerate negative news; avoid blindly following the trend
