Bitcoin slides below $77,000, BNB drops amid Binance hack

Bitcoin experienced a sharp decline of 4.87 percent, reaching US$77,037.20 in a single day, underperforming the overall crypto market. The primary cause was a security breach at Binance, which occurred on October 29th. This incident significantly impacted Bitcoin due to its strong correlation with the S&P 500, which is around 65 percent. The market had already entered a defensive mode due to macro risk aversion.

The breach involved hot wallets and estimates suggest that between US$2 billion and US$6 billion were affected, making it potentially the largest cryptocurrency heist in history. Traders swiftly sold their assets before Binance provided further details, demonstrating the cautious nature of the market when the central counterparty appears vulnerable.

Binance's executives reassured users by stating that the company would cover all hacking losses using its capital margins and its Secure Asset Fund for Users (SAFU). Major crypto entities also froze assets totaling roughly US$3 billion to mitigate the impact of the theft. However, this containment effort does not fully restore normal deposit and withdrawal processes, contributing to ongoing market uncertainty.

The initial price drop triggered leveraged liquidations amounting to over US$629 million in just one hour, primarily consisting of bullish long positions. This behavior indicates that the market was heavily over-leveraged and susceptible to sudden shocks. Bitcoin's underperformance relative to the overall weaker crypto sector highlights a specific loss of confidence rather than a uniform risk-off move.

The correlation between the Binance incident and the broader financial market suggests that the decline was not solely driven by the security breach. Instead, it was amplified by existing market sentiments and the macro-driven selloff in risk assets. Bitcoin's performance is increasingly influenced by its correlation with traditional financial markets, turning it into a high-beta risk asset during times of volatility.

Technically, Bitcoin's 14-day relative strength index is in oversold territory, suggesting that the immediate selling pressure may be nearing exhaustion. However, the price is testing a critical support band between US$76,264 and US$76,476. If this support holds and Binance confirms the incident with a verified update, a rebound toward the 50-day exponential moving average near US$80,789 could occur.

Conversely, a break below the US$76,264 support level would open the path to the next major demand zone near US$75,800, intensifying pain for recent buyers.

In conclusion, the Binance security breach and its immediate market impact highlight the systemic risks within the cryptocurrency industry. While measures like freezing stolen assets are effective in reducing the final damage, they do not address the underlying vulnerabilities. The episode emphasizes the need for greater transparency, accountability, and robust risk management practices to prevent future occurrences from spiraling into such severe liquidation cascades.
