On-chain data has revealed a significant case of "panic selling" by a prominent market participant following the historic security breach at Binance. A whale associated with revolving credit loans liquidates a substantial position in cbBTC (Coinbase Wrapped BTC) during the market downturn, only to buy back a portion of the assets at a higher price as the market stabilized. This event highlights the volatility and emotional decision-making often triggered by major exchange security incidents.
On-Chain Activity and Panic Selling Details
According to monitoring by on-chain analyst Yu Jin, the whale address 0xc79b executed a series of high-stakes transactions following news of the October 29, 2026, Binance hack, which saw approximately $6.3 billion in digital assets stolen. Fearing a broader market collapse, the whale sold 288.1 cbBTC for approximately 22.35 million USD at a price of $77,592 per token.
The asset cbBTC is an ERC-20 tokenized version of Bitcoin issued by Coinbase, backed 1:1 by Bitcoin reserves, and frequently used in decentralized finance (DeFi) protocols on the Base and Ethereum blockchains.
The sale occurred during a period of extreme market anxiety. However, Bitcoin (BTC) prices proved resilient, rebounding toward the $81,000 mark shortly after the initial panic. During a subsequent minor dip on the night of November 5, the same whale attempted to re-enter their position but faced a less favorable entry point.
- Initial Sale: 288.1 cbBTC at $77,592 (Total: $22.35M)
- Buyback: 203.6 cbBTC at $77,804 (Total: $15.85M)
- Result: Purchase price was slightly higher than the previous exit price.
Market Context: The Largest Theft in Record
The whale's decision to liquidate was likely influenced by the sheer scale of the Binance heist, which has been described by investigators as the largest cryptocurrency theft to date. The Federal Bureau of Investigation (FBI) has attributed the attack to the North Korean-linked hacking unit TraderTraitor.
"Blockchain records indicate most of the money left in about 20 minutes... this is almost certainly the single largest-known theft of any kind", noted analysts reviewing the $6.36 billion outflow across ten different blockchains.
Despite the gravity of the hack, Binance's commitment to fully absorb the losses and the successful freezing of roughly $3 billion in stolen assets helped prevent a sustained market freefall. By November 5, BTC was trading near $76,000–$77,000 following a tech-stock-led correction on Wall Street, providing the whale with an opportunity to buy back 203.6 cbBTC, though they effectively reduced their total Bitcoin holdings in the process.
The behavior of whale 0xc79b serves as a cautionary tale regarding the risks of reactive trading during "Black Swan" events. While the Binance breach initially spooked large-scale holders, the rapid institutional response and the exchange's "Secure Asset Fund for Users" (SAFU) effectively mitigated a total market capitulation, leaving those who panicked to chase the subsequent rebound.
