What is a crypto whale?
A whale is a person or organisation that holds a very large amount of a cryptocurrency compared with the rest of the market. The IMF notes holdings of many crypto assets can be concentrated in the hands of a few whales.
What it means for you
When a few wallets hold much of a coin's supply, one large sale can move the price sharply, and the IMF lists whale trades among the market-manipulation risks in illiquid markets. Before buying a small coin, check how much of the supply its top wallets hold; a block explorer shows this.
How it works
The IMF uses "whale trade" for a trade by one trader or entity whose position is large enough to move the market. In thin crypto markets, one sale by such a holder can drop the price sharply, and the IMF groups whale trades with pump-and-dump schemes as manipulation risks that illiquidity makes easier. FSOC adds a second channel: whales borrowing or lending large amounts on a single platform. If such a position loses value or is liquidated, the platform and its other users can come under pressure, as when one large withdrawal from a lending protocol sent its lending and borrowing rates spiking within hours.
