whale
An investor or trader holding very large amounts of cryptocurrency or assets.
A whale is someone who owns enough cryptocurrency or other assets to significantly influence markets through their buying and selling. The term comes from the idea that whales are the largest creatures in the ocean. In crypto and finance, whales typically control millions or billions of dollars worth of assets.
Whales matter because their large trades can move prices up or down, sometimes dramatically. When you see headlines about whale activity, it’s usually because their moves are being tracked to predict market direction or because their actions reveal something about insider sentiment. For ordinary investors, whale activity is worth noting but shouldn’t drive your own decisions—large players often have different goals and risk tolerances than everyday traders.
