An account linked to the notorious “Coinbase hacker,” implicated in a significant data breach in May 2025, has recently been under scrutiny for cryptocurrency trading activities. This individual or group reportedly acquired 3,976 ETH, valued at nearly $18.9 million, on September 13. However, just two days later, during a market downturn, they liquidated their entire position at a loss of approximately $932,000, selling at $4,522 per ETH.
The breach that linked the Coinbase hacker to stolen funds involved sophisticated tactics that deceived users into transferring their assets, leading to estimated losses between $180 million and $400 million. On-chain analysts, including popular sleuth ZachXBT and platforms like Arkham Intelligence, have been tracking the hacker’s transactions, identifying a notable address which played a key role in the fraudulent activities.
The trading activities raise questions about how a known hacker can operate freely in the cryptocurrency market. Critics voiced their concerns on social media, suggesting that existing systems fail to impose necessary sanctions on those labeled as hackers. Experts explain that this leniency arises from the nature of decentralized exchanges, like CoW Protocol, which facilitate trading on censorship-resistant platforms. These decentralized networks empower users to transact without interference, complicating efforts to restrict traders linked to criminal activities.
Trading on decentralized networks comes with inherent risks, yet they also provide a vital outlet for those affected by political oppression or instability. The fundamental principle of decentralized finance—“code is law”—means that preventing such trading requires robust systems designed to withstand breaches or tools that anonymize user activity.
As Ethereum approaches a pivotal support level of $4,505, following a significant period of volatility, its future in the wake of the upcoming Federal Reserve interest rate decision remains uncertain. The native token’s price has held above the 50-day exponential moving average since a major rally in May, coinciding with when the hacker began accumulating stolen funds.
Analyzing current market conditions, Ethereum’s performance is pivotal. Should it maintain or bounce back from the $4,505 level, bullish momentum could be expected. Conversely, falling below this threshold may lead to further declines, testing the limits of investor confidence as cryptocurrency operates amid a complex landscape of regulation and market dynamics.
