Whale
A whale is a market participant, address or wallet that holds or moves an unusually large amount of a cryptocurrency. Their trades can be big enough to move the price on their own.
Who counts as a whale
There is no official threshold. The word simply means someone whose holdings are large relative to the market. In Bitcoin, analysts often use cut-offs such as 1,000 BTC per address, but the line is a convention, not a rule. In a small token, a wallet holding a few percent of the supply can be a whale.
Whales include early adopters, investment funds, companies holding coins on their balance sheet, exchanges, and sometimes token teams or their investors.
How whales can move markets
Order books have limited depth. If a whale sells a large amount at once with a market order, it eats through many buy orders and pushes the price down sharply. That is why large holders often split trades into smaller pieces, use over-the-counter (OTC) desks, or trade slowly over days.
In thinly traded tokens, a single whale can dominate price action. If a handful of addresses hold most of the supply, the risk that they sell into the market is a real factor for everyone else.
An example
Imagine a token where buy orders within 5 percent of the current price add up to about 500,000 dollars. A whale who dumps 2 million dollars' worth in one go would push the price far more than 5 percent lower, and smaller holders with stop-loss orders could be triggered, deepening the drop.
Common mistakes when watching whales
Blockchains are public, so large transfers are easy to see, and alert services report them constantly. The problem is interpretation. A big wallet is often not one person: exchange cold wallets, custodians and smart contracts hold coins for thousands of users. A large transfer may be an exchange moving funds internally, not a sale.
Copying whales blindly is also risky. You rarely know their reasons, their time horizon or whether they are hedged elsewhere. Treat whale activity as one piece of context, not a trading signal.

Frequently asked questions
How much crypto do you need to be a whale?
There is no fixed number. It depends on the coin and on who is defining it; the point is that the holding is large enough to matter for the market.
Can you see what whales are doing?
You can see on-chain transfers between addresses, but not always who owns them or why. Trades on exchanges and OTC deals are largely invisible on-chain.
Is a whale transfer to an exchange a sell signal?
Not by itself. Coins sent to an exchange may be sold, but they may also be used as collateral, moved between accounts, or left untouched.
