A large holder believed to be an early Ethereum (ETH) investor is seen moving all holdings to a centralised exchange, effectively exiting the Ethereum position. On-chain analysis estimates the investor made about $274 million in profit from the sale.

On-chain analytics firm Lookonchain, cited by blockchain outlet BeInCrypto on Sunday, said the investor accumulated a total of 154,076 ETH at an average purchase price of about $517. The wallet has transferred the Ethereum holdings in stages to the centralised exchange Bitstamp over the past few weeks.

Lookonchain said the investor stepped up transfers from late last week and deposited an additional 40,251 ETH over the past two days alone. The investor then moved the final remaining 26,000 ETH to the exchange, appearing to complete a full sale. That implies a return of about 344 percent across the transactions.

Arkham data show the transfers to exchanges did not happen over a short period but progressed gradually from about eight months ago. The investor first sent small amounts of ETH as a test, then transferred an additional 17,000 ETH three months ago and 18,000 ETH a month ago in a staged exit strategy.

Some in the market also interpret the move as more than an individual taking profits, linking it to broader caution among institutional investors facing Ethereum.

Ethereum's Coinbase premium index remains clearly in negative territory. The indicator, often used as a gauge of U.S. institutional sentiment, shows the price gap between Coinbase, where U.S. institutional trading is relatively heavy, and global exchanges. A negative reading is interpreted as relatively strong U.S. institution-led selling pressure.

Some analysts raise the possibility the trend could continue through 2026, and say institutional investors are still maintaining conservative positions.

Not all market participants are pessimistic. Analyst Quinten Francois said Ethereum is significantly undervalued when comparing on-chain economic activity with the current price.

Milk Road also said the scale of payment and economic activity on the Ethereum network is steadily increasing, but the price is not fully reflecting it. It cited the fact that large investors are still choosing Ethereum first in terms of uptime, liquidity, payment stability and regulatory clarity.

Some traders, citing a breakdown of a falling wedge pattern and the end of a long consolidation range, are also projecting Ethereum could rebound with a medium-term target above $4,400.

The Ethereum market is in a phase where short-term risks from profit-taking by early whale investors and institutional selling pressure are operating at the same time as long-term fundamentals driven by expanding network economic activity.

The exit of early adopters is interpreted as a warning signal, but on-chain usage and ecosystem growth remain strong. Whether Ethereum's price can ultimately follow those fundamentals is expected to be confirmed through future market moves.
