Crypto traders are advised to monitor unusual market movements as large transaction volumes may indicate whale activity, potentially causing significant price fluctuations. Onchain analysis is crucial for detecting these movements, particularly high-value transfers between non-exchange wallets. A sudden increase in trading volume, coupled with large buy or sell orders, can signal market shifts. Observing the inflow and outflow of cryptocurrencies from whales to exchanges is essential for anticipating price corrections or breakouts. Tools like "whale alert" on onchain monitoring platforms are valuable for gaining insights beyond traditional charts.
