What is Pump and dump?
Coordinated promotion of a thinly-traded stock or crypto to drive the price up, followed by the promoters selling while retail buyers are still piling in.
A pump-and-dump is a manipulation scheme where promoters hype a thinly traded stock or crypto to drive the price up, then sell their own holdings into the buying frenzy — leaving latecomers holding a collapsing price. The 'pump' is the coordinated promotion; the 'dump' is the insiders cashing out at the top.
Social media has made these rampant, with coordinated campaigns pushing obscure tickers or tokens as the next big thing. The tell is aggressive, synchronised promotion of a little-known asset promising fast, guaranteed riches, often with urgency ('get in before it explodes'). Because the asset is thinly traded, a burst of hype-driven buying moves the price sharply — until the promoters sell, the buying dries up, and the price crashes back down, usually below where the victims bought.
Promoters hype an obscure asset to spike the price, then sell into the frenzy, leaving latecomers with a crash. By the time you hear of the 'sure thing', you're the exit liquidity.
For example
An obscure token is suddenly hyped across social media as a 'guaranteed 10x'; it spikes as newcomers pile in, then crashes the moment the promoters dump their holdings.

Pump-and-dumps matter because social media has industrialised them, and the victims are ordinary investors drawn in by FOMO and the fear of missing a fast fortune. Recognising the pattern — coordinated hype around an obscure, thinly traded asset with promises of guaranteed, rapid gains — is the defence, since by the time you hear about a 'sure thing', you're likely the exit liquidity the promoters are selling to. Genuine opportunities aren't marketed this way.
⚠ Buying into coordinated hype
When an obscure stock or token is suddenly everywhere, promoted as a guaranteed, imminent windfall, the promotion itself is the danger — you're likely being recruited as the buyer the promoters will sell to. Chasing a coordinated hype wave means buying near the top of a manufactured spike. Broad, sudden promotion of an unknown asset is a reason for suspicion, not excitement.
