Whale
A whale is an individual or entity holding a very large amount of a cryptocurrency — enough that their buying or selling can move the market. There is no official threshold; for bitcoin, addresses holding 1,000 BTC or more are commonly labeled whales, while for smaller tokens a far more modest holding can dominate the market. Whales include early adopters, funds, exchanges, corporate treasuries, and in some cases governments holding seized coins.
Whales matter because crypto markets are thinner than traditional ones, so concentrated holdings translate into real price power. A whale selling a large position into a quiet market can push the price down sharply, and large transfers to exchanges are often read as a prelude to selling. This is why "whale watching" is a genre of crypto analysis: because blockchains are public, services track large wallets and broadcast alerts when significant sums move. For example, an alert that a dormant wallet from 2011 just moved thousands of BTC to an exchange will circulate within minutes and can itself affect sentiment before any sale occurs.
A common misconception is that every large on-chain transfer signals an imminent dump; many big movements are exchanges reshuffling internal wallets, custody migrations, or over-the-counter deals that never touch the open market. Whale concentration is also a useful risk signal when researching small tokens — if a few wallets hold most of the supply, holders are exposed to those wallets' decisions. Smaller holders are sometimes playfully called fish or shrimp.
