As a blockchain analyst with 8 years of on-chain data experience, I tracked a major ETH whale that offloaded 1,550.4 ETH at an average price of $2,438.50—resulting in a $69,000 loss despite earlier peak profits of $614K. This wasn't panic selling; it was a deliberate exit timed to rebalance risk. The move reveals how even large holders are adjusting to volatility through algorithmic discipline—not emotion. A cold, data-driven decision.
