Culper Research: Why We Are Firmly Committed to Shorting ETH

DeepFlowTech · 2026-03-06T11:15:53+00:00

Culper Research released a report stating that the Ethereum token economy model has collapsed, mainly because the cheap block space resulting from the Fusaka upgrade in 2025 has not generated real demand, and the actual data has been falsified by newly created "toxic" wallets. Vitalik frequently sells ETH, indicating his pessimistic outlook for the future. The report warns investors that $ETH will continue to decline and recommends carefully examining on-chain data and its true significance.

Deep Tide Overview: Culper Research is a well-known Wall Street short-selling firm that has accurately targeted several high-profile companies. This report directly addresses Ethereum’s core issues: the Fusaka upgrade in December 2025 brought a large amount of cheap block space, but genuine organic demand has not kept pace—the so-called “prosperity” on-chain is actually fabricated through address poisoning attacks. Vitalik himself has been selling ETH extensively, while Ethereum’s most steadfast bull advocate, Tom Lee, continues to defend it with flawed data. This article is not a prediction but a data-backed, verified short thesis worth reading carefully for anyone holding ETH.

We are shorting Ethereum and ETH-linked securities, including BMNR.

We believe the December 2025 Fusaka upgrade has severely damaged Ethereum’s tokenomics. Vitalik is aware of this and continues to sell; meanwhile, ETH’s most committed bull, Tom Lee, is pouring good money into a bad bet.

$ETH will continue to decline.

Tom Lee’s Defense: Active Addresses and Transaction Volume Are Rising

Tom Lee’s $BMNR defends ETH, claiming “ETH is not entering a death spiral because its utility is increasing.” He cites the surge in active addresses and transaction volume after Fusaka as evidence of “fundamental strengthening” and institutional adoption.

Lee’s logic is flawed.

According to his own logic, if ETH’s on-chain activity does not reflect real growth in utility, then ETH is heading toward a death spiral.

Our research shows that this is exactly what is happening.

The Truth About On-Chain Data: 95% of New Wallets Are Poisoning Attacks

Our comprehensive analysis of on-chain data from January 2025 to February 2026 reveals that the “institutional adoption” figures Tom Lee cites are actually explained by large-scale address poisoning (address poisoning) and wallet dusting attacks caused by the excess block space after Fusaka.

Specific data after Fusaka:

95% of new wallets are explained by newly created “poisoned” wallets
Address poisoning attacks increased more than threefold
Poisoning attacks account for over 50% of ETH transaction volume growth
Poisoning attacks now make up 22.5% of all ETH transactions

Fusaka Upgrade: Gas Fees Collapsed by 90%, Much Worse Than Expected (by 3-9x)

Fusaka increased the gas cap from 45 million to 60 million, aiming to expand Ethereum L1. Vitalik and PTG estimated gas fees would drop by 10-30%.

Reality: gas fees have fallen by about 90%.

Vitalik and validators severely underestimated L1 demand elasticity, with errors of 3-9 times—using outdated math models from before EIP-1559 and L2 emergence.

Vitalik is Selling Frenziedly

This is why we believe Vitalik is massively selling ETH. On January 30, he announced plans to sell 16,384 ETH to fund Ethereum Foundation’s “contraction phase.” Since then, he has sold over 19,300 ETH and continues to sell.

He knows what Tom Lee does not: ETH’s tokenomics have already collapsed.

We personally verified address poisoning attacks

We conducted on-the-ground testing of address poisoning: creating two new wallets, transferring between them, and being targeted by poisoning attacks within five minutes.

We encourage readers to verify for themselves.

Losses from poisoning attacks are growing at over 8 times the rate before Fusaka.

Validator’s Flywheel Is Reversing

Additionally, the increased gas cap has severely hurt ETH validators, whose tips per unit of gas have dropped by 40-50%. Lower rewards reduce staking demand and high-value activities, further weakening institutional adoption foundations.

The flywheel is now reversing.

Ethereum Is Losing to Solana and Its Own L2

Meanwhile, ETH continues to cede market share:

Solana developer growth in 2025: +29%, Ethereum only +6%; talent is fleeing
Visa and Citigroup are choosing Solana to build DeFi applications
Solana DEX trading volume is now more than twice that of Ethereum

Conclusion: The Next Nokia

During the dot-com bubble, Netscape and Nokia dominated the market for over a decade, only to be overtaken by Google and Apple.

We see ETH in the same light.

We believe the tokenomics have already collapsed, Tom Lee is in a difficult position, and $ETH will continue to decline.

ETH-4,95%

SOL-4,28%
