A pump and dump is market manipulation: organizers inflate a token's price with hype and coordinated buying (the "pump"), then sell into the demand they created (the "dump"), leaving latecomers with losses. This guide explains it.
How it works
A small group accumulates a low-liquidity token cheaply, then promotes it aggressively — social posts, paid influencers, manufactured urgency — to draw in buyers and drive the price up [1]. Once enough new money arrives, the organizers sell their holdings at the inflated price. The price collapses, and those who bought near the top are left with losses [2].
Why low-liquidity tokens
Pump-and-dumps target thinly traded tokens because a small amount of buying moves the price sharply, making the "pump" easy to engineer and the "dump" devastating. The same dynamic makes a recovery unlikely once the organizers exit.

How to protect yourself
Be skeptical of sudden price spikes paired with coordinated hype, time-pressure messaging, and promises of guaranteed gains. In regulated markets, pump-and-dumps are illegal market manipulation, and they are a frequent crypto scam (see our common crypto scams guide).
The bottom line
A pump and dump inflates a price on hype, then sells into it — by design, latecomers lose. Recognizing the pattern keeps you from becoming someone else's exit liquidity. To keep learning the fundamentals, follow more from Bitbase Academy.
