Crypto whales, individuals or entities with significant cryptocurrency holdings, can greatly influence the market. They often amass their wealth through early adoption, strategic investments, mining, and trading profits. Tools like blockchain explorers, whale alert services, on-chain analytics, and social listening tools can track whale activity, providing insights into market trends and potential price movements. To protect their identities, whales use multiple wallets, privacy coins, off-exchange storage, legal entities, and tax havens. However, they must balance anonymity with compliance to avoid legal complications.
