Whale Watching: How Crypto Investigators Unmask Anonymous Wallets

A crypto whale is defined as any wallet or entity holding enough Bitcoin, Ethereum, or another asset to move its price with a single trade. While their transactions are visible on public blockchains, whales work hard to keep their identities anonymous.

Whales rely on pseudonymous wallet addresses instead of hiding transactions outright. Every trade is permanently visible on the blockchain, but the name behind the wallet remains hidden. Address splitting, privacy tools, and off-chain habits limit what investigators can connect back to them.

The gap between 'visible transaction' and 'invisible owner' is shrinking due to AI-assisted address clustering and entity attribution platforms such as Arkham Intelligence. Even with these protections in place, whales still use methods to protect their privacy, but their effectiveness is limited.
