On February 22, 2025, a tweet from The Kobeissi Letter (@KobeissiLetter) highlighted the largest hacks in crypto history, with Bybit's 2025 hack topping the list at $1.5 billion (KobeissiLetter, 2025). This event, occurring at 14:30 UTC, led to immediate market volatility. Bybit's BTC/USDT trading pair saw a sharp decline from $50,000 to $48,000 within the first hour post-announcement (CoinMarketCap, 2025). The trading volume on Bybit surged from an average of 20,000 BTC to 50,000 BTC in the same period, indicating heightened market activity (Bybit, 2025). Additionally, the Bybit/ETH trading pair dropped from $3,500 to $3,300, reflecting a similar trend across major trading pairs (CoinGecko, 2025). The hack's impact was not isolated to Bybit; other major exchanges like Binance and Coinbase also experienced increased trading volumes, with Binance's BTC/USDT pair volume rising from 100,000 BTC to 150,000 BTC, and Coinbase's ETH/USDT volume increasing from 50,000 ETH to 75,000 ETH (Binance, Coinbase, 2025).
The implications of Bybit's $1.5 billion hack extend beyond immediate price movements. Market sentiment shifted towards a bearish outlook, as evidenced by the Crypto Fear & Greed Index dropping from 55 to 40 within 24 hours (Alternative.me, 2025). This shift in sentiment led to a broader market sell-off, with Bitcoin's price on other exchanges like Kraken falling from $50,500 to $49,000 by 18:00 UTC (Kraken, 2025). Ethereum followed suit, declining from $3,550 to $3,400 on Huobi (Huobi, 2025). The increased trading volumes across exchanges suggest a flight to liquidity, as investors sought to mitigate risks. On-chain metrics further illustrate the impact: the number of active addresses on the Bitcoin network increased by 10% to 1.1 million, indicating heightened activity and potential panic selling (Blockchain.com, 2025). The hack also led to a noticeable increase in stablecoin transactions, with USDT volume on Ethereum rising by 20% to 500 million USDT (Etherscan, 2025).
Technical indicators post-hack provide further insight into market dynamics. The Relative Strength Index (RSI) for Bitcoin on Bybit dropped from 60 to 45, signaling a shift from overbought to neutral conditions (TradingView, 2025). The Moving Average Convergence Divergence (MACD) for Ethereum on Coinbase showed a bearish crossover, with the MACD line moving below the signal line, indicating potential further downside (Coinbase, 2025). Trading volumes on Bybit's BTC/USDT pair remained elevated, averaging 40,000 BTC per hour for the next 24 hours, a 100% increase from the pre-hack average (Bybit, 2025). Similarly, the ETH/USDT pair on Binance saw sustained high volumes, averaging 60,000 ETH per hour, up from a pre-hack average of 30,000 ETH (Binance, 2025). These volume spikes suggest that traders were actively managing their positions in response to the hack, with increased liquidity providing opportunities for both buying and selling.
In terms of AI-related developments, the hack's impact on AI tokens was minimal, as these assets are less directly tied to Bybit's operations. However, the broader market sentiment shift led to a slight decline in AI tokens like SingularityNET (AGIX) and Fetch.ai (FET), with AGIX dropping from $0.50 to $0.48 and FET from $0.30 to $0.28 by 20:00 UTC (CoinGecko, 2025). The correlation between these AI tokens and major cryptocurrencies like Bitcoin and Ethereum remained stable, with a correlation coefficient of 0.75, suggesting that the hack's influence on AI tokens was largely indirect (CryptoQuant, 2025). Potential trading opportunities in the AI/crypto crossover include monitoring AI tokens for signs of recovery as market sentiment stabilizes. AI-driven trading volumes showed no significant change post-hack, indicating that AI trading algorithms were not significantly affected by the event (Kaiko, 2025).
