Spoofing
Spoofing is placing large buy or sell orders you never intend to execute, then cancelling them quickly, to mislead other traders about supply and demand. It is a form of market manipulation and is illegal in regulated markets.
How spoofing works
Many traders and trading bots read the order book, the list of open buy and sell orders. A wall of large buy orders below the price looks like strong demand; a wall of sell orders above looks like heavy supply.
A spoofer exploits this. They place a big order on one side to create a false impression, wait for others to react, trade on the other side at a better price, and then cancel the big order before anyone can fill it.
An example
Say a coin trades at 10.00. A spoofer wants to sell 50,000 tokens at a higher price. They place buy orders for 2 million tokens at 9.95. Other traders see the huge bid, assume the price is well supported and start buying, pushing the price to 10.10. The spoofer sells their 50,000 tokens into that demand, then cancels the 2 million token bid. The support was never real, and the price drifts back down.
Is spoofing legal?
In regulated markets it is not. In the United States, the Dodd-Frank Act of 2010 explicitly made spoofing illegal in futures markets, and regulators have since brought cases against traders and banks. Many other jurisdictions, including the EU under its market abuse rules, treat it as market manipulation too.
Crypto spot markets are unevenly regulated across countries and exchanges, and supervision of order-book activity varies a lot. That makes spoofing harder to police there, although exchanges' own rules usually forbid it.
How to protect yourself
Treat large walls in the order book as information that can disappear, not as a promise. Orders that keep appearing and vanishing just before the price reaches them are a classic warning sign.
Thin markets, such as small tokens, are easiest to spoof because a relatively small fake order looks large. Relying on executed volume and price action rather than resting orders reduces the chance of being misled.

Frequently asked questions
Is cancelling orders spoofing?
No. Traders cancel orders all the time for legitimate reasons. Spoofing requires intent: the order was placed never meaning to execute it, in order to deceive.
How can I recognise spoofing?
Watch for very large orders near the price that are repeatedly pulled when the market approaches them. Certainty is hard from the outside, so treat order-book walls with caution.
Is spoofing the same as wash trading?
No. Spoofing fakes intentions with orders that are cancelled. Wash trading fakes activity with trades that actually execute, but where the same party is effectively on both sides.
