A pump and dump is a market manipulation scheme in which a coordinated group of traders buys a token to inflate its price, generates attention and FOMO among outside buyers, and then sells their holdings simultaneously into the demand they created. The outside buyers who bought during the pump phase are left holding at elevated prices as the dump drives the price back down.
Mechanics
Classic pump and dump execution follows a pattern:
- A group of traders quietly accumulates a low-liquidity token at low prices
- The group begins public promotion — social media posts, Telegram shills, CT posts from KOL accounts
- Retail buyers see the promotion and rising price, FOMO in
- The coordinating group sells their accumulated position into the retail buying, extracting profit
- Price collapses as selling pressure overwhelms new buyers; late buyers are left holding
Pump and dump vs. organic pumps
The line between a coordinated pump and dump and an organic pump that attracts genuine retail interest is not always clear from the outside. Both can look identical on charts. The key differentiator is the intent and presence of a coordinating group. In practice, many organic-seeming pumps in low-cap tokens have some coordination behind them; distinguishing which type you're entering is difficult.
Legality
Pump and dump is explicitly illegal in regulated securities markets. Cryptocurrency markets occupy a more ambiguous legal space, but major jurisdictions have increasingly applied market manipulation prohibitions to crypto assets. The practical enforcement environment remains inconsistent.
