What is Pump & Dump?
Crypto Glossary Definition
A coordinated manipulation of the price of an asset. A whale or group of people all start buying a cryptocurrency causing the price to drastically increase very rapidly. This often causes wild speculation and others start buying it out of excitement. The original actors immediately sell everything they originally bought causing the price to come tumbling back down.
Why Pump & Dump Matters
In a pump and dump, a coordinated group buys a low-liquidity coin to drive the price up, generates hype to draw in outside buyers, then sells into that demand, leaving latecomers holding losses. Low-market-cap, low-liquidity coins with sudden unexplained price spikes are the classic warning sign.
Pump & Dump in Practice
A trader browsing a low-cap altcoin discord notices an unusual amount of coordinated excitement building around a token with barely any daily trading volume. Within an hour, the price triples, driven by a small group of early holders who quietly accumulated the coin days earlier and are now flooding social media and Telegram channels with bullish charts and promises of an imminent exchange listing. Newcomers, afraid of missing out, start buying in, pushing the price even higher and generating the kind of parabolic candlestick chart that gets shared across trading forums. Once the price peaks, the original group — who bought cheaply before the hype campaign began — sells their entire position into the buying frenzy they manufactured, and liquidity dries up almost instantly. The chart collapses just as fast as it rose, often losing most of its gains within minutes, leaving the latecomers holding a bag of rapidly depreciating tokens with nowhere to sell. This pattern repeats constantly with thinly traded microcap coins, and experienced traders learn to treat sudden, unexplained volume spikes on obscure tokens as a red flag rather than an opportunity, checking things like token holder concentration and liquidity pool depth before ever considering a trade.
