In the fast-paced world of crypto, even hackers aren't immune to the whims of market volatility. A recent tweet from on-chain analytics firm Lookonchain highlights a dramatic turn for the perpetrator behind the massive $300 million-plus theft from Coinbase users. This individual, who bribed Coinbase support staff back in May 2025 to access user data and siphon funds, just executed a panic sale of 3,976 ETH—worth about $17.98 million—at $4,522 per token. That's a hefty $932,000 loss in just two days after buying the same amount at $4,756.

This move comes on the heels of the hacker's earlier purchase, as detailed in Lookonchain's previous post. Using stablecoins like DAI to swap through CoW Protocol—a decentralized exchange aggregator that helps users get better prices by batching trades—the hacker appears to have gotten cold feet amid a dip in ETH's price.

For those new to the story, the hack involved social engineering tactics where the culprit bribed insiders at Coinbase, one of the largest crypto exchanges, to steal user credentials and drain accounts. According to reports from sources like Cointelegraph and Binance Square, the total haul exceeded $300 million, much of it laundered through various chains.

Since then, on-chain trackers like Lookonchain and Arkham Intelligence have labeled and monitored wallets associated with the hacker, such as 0x15f4c13E0cA461e0ef23F6d35Bbeb5dCE2495879. These addresses show a pattern of strategic—and sometimes erratic—investments, including dips into major assets like ETH and SOL.

The Hacker's Foray into Solana and Meme Token Ecosystems

What's particularly intriguing for meme token enthusiasts is the hacker's activity on Solana. Back in August 2025, as per Lookonchain's update, the hacker scooped up 38,126 SOL for around $7.95 million when SOL was trading at $209. Solana is a hotbed for meme tokens, hosting viral projects like Bonk, Dogwifhat, and countless others that thrive on community hype and rapid price swings.

While there's no direct evidence of the hacker diving into specific meme coins, their SOL holdings position them to potentially engage with the ecosystem. Solana's low fees and high speed make it ideal for meme token trading, and large inflows like this could indirectly boost liquidity and sentiment in the meme space. Imagine if some of those stolen funds trickle into pump-and-dump schemes or new launches—it underscores the shadowy side of decentralized finance where illicit gains fuel speculative markets.

This saga isn't just about one bad actor's misfortune; it's a stark reminder of the risks in crypto trading, especially for meme tokens. Meme coins are notoriously volatile, often swinging wildly based on social media buzz, whale movements, or macro events. The hacker's panic sell mirrors what many retail traders experience—buying high on FOMO (fear of missing out) and selling low in a panic.

On-chain analysis tools like those from Lookonchain reveal these moves in real-time, helping savvy traders spot opportunities or avoid pitfalls. For instance, the hacker has a history of mistimed trades: selling 26,762 ETH for $69.25 million at $2,588 in May 2025, only to buy back in later at higher prices. Compare that to other hackers, like the Cetus exploiter, who timed buys better during dips.

Additionally, the hacker's taunting on-chain message to crypto sleuth ZachXBT—sent alongside another ETH-to-DAI swap in May—adds a layer of bravado. ZachXBT, known for exposing scams in the meme and NFT spaces, received a provocative note embedded in a transaction, highlighting how blockchain's transparency can backfire on criminals.

As blockchain practitioners, keeping tabs on such events sharpens our understanding of market dynamics. Meme tokens, built on hype and community, can be influenced by whale activities like this. If you're trading memes on Ethereum or Solana, tools like Arkham Intelligence or Etherscan can help monitor big wallets for signs of dumps or accumulations.

Remember, volatility cuts both ways—while the Coinbase hacker nursed a loss, patient holders in the meme space have seen massive gains. Always DYOR(스스로 조사하세요), diversify, and avoid emotional trading. In the end, even those with stolen millions can fumble, proving that no one beats the market every time.
