Whale movements are trading signals from large-cap players and often serve as market indicators. Recently in the crypto circle, a certain whale transferred 5,000 BTC from an exchange to a cold wallet, suspected of long-term accumulation; another institution simultaneously reduced its ETH holdings, leading to increased short-term selling pressure. These operations can be tracked through on-chain data—accumulation or profit-taking signals are positive, while reduction adds volatility. Retail investors need to understand the logic—whales are not always precise, so before following the trend, observe the underlying market sentiment.
