**[4E: Crypto Market Flash Crash of $1.2 Billion; Whale Liquidation; Bitcoin Cycle Pattern May End]** According to 4E's observation, the crypto market experienced a sudden flash crash on Monday, with over $1.2 billion liquidated within 24 hours, of which long positions accounted for more than 90%. Bitcoin briefly dropped from $108,000 to $105,000, while Ethereum plunged from $3,700 to $3,500. Both saw liquidation amounts exceeding $100 million within an hour. During the crash, the Coinbase Bitcoin Premium Index remained around -$30, indicating that U.S. investors may have been the dominant selling force. Monitoring platform "Ember" revealed that the account known as the "100% Win Rate Whale" liquidated $258 million worth of BTC, ETH, and SOL long positions 8 hours ago, incurring a loss of $15.65 million—almost wiping out all profits from the past 20 days. The account currently holds approximately $148 million in long positions, with an unrealized loss of $18.86 million. CryptoQuant CEO Ki Young Ju pointed out that Bitcoin's "four-year halving cycle" model may no longer apply. His analysis suggests that whale unrealized profit margins are in a neutral range, mining companies continue to expand, ETF and MicroStrategy buying activity has slowed, short-term whales are near breakeven, while long-term whales still maintain about 53% profit. Overall on-chain data indicates that the market has shifted from being cycle-driven to liquidity-driven by institutions. **4E Commentary:** The flash crash reflects the fragility of high-leverage structures and the pressure linked to rising U.S. Treasury yields. If Bitcoin enters a "non-cycle" phase, future volatility will rely more on institutional capital flows and macro liquidity signals rather than historical patterns.
