What is a crypto whale?

A crypto whale is a person or entity holding a large enough amount of a cryptocurrency that their trades can move its price. This matters because a single whale selling a big position can crash a thin market in minutes, while a whale buying can spark a rally, so traders watch their wallets closely.

There's no fixed cutoff, but on Bitcoin, addresses holding 1,000 BTC or more (worth tens of millions of dollars) are typically labeled whales. On smaller altcoins with less liquidity, even a $500,000 holding might qualify.

Whale activity gets tracked through on-chain analytics tools like Whale Alert, which post real-time alerts when large transfers hit exchanges. Readers should note that a whale moving coins to an exchange doesn't always mean they're selling; it could be for custody, staking, or an over-the-counter deal instead.
