Pump and Dump

A pump and dump strategy is a type of investment scam where a group of individuals artificially inflate the price of a particular asset, then sell it off at a profit, leaving other investors with losses. In the context of cryptocurrency, this typically involves a group of traders who coordinate to buy large quantities of a low-liquidity token, creating the appearance of surging demand. As the price rises rapidly, uninformed retail investors are drawn in by the excitement and fear of missing out, pushing the price even higher.

Once the price reaches a target level, the original group — often called the "pump group" — sells their holdings all at once. This sudden wave of selling collapses the price, and latecomers who bought in near the top are left holding assets worth a fraction of what they paid. These schemes are often promoted through social media, messaging apps like Telegram, or Discord servers, where organizers use hype, fake news, and coordinated buying signals to attract participants.

Pump and dump schemes are illegal in traditional securities markets, and regulators in many jurisdictions are increasingly applying similar rules to cryptocurrency. However, the pseudonymous and decentralized nature of crypto markets makes enforcement difficult. The best protection is skepticism: sudden, unexplained price surges in low-cap or obscure tokens are a common warning sign. Algorithmic traders should be especially cautious about entering positions based on volume spikes that are not supported by any fundamental news or on-chain activity.
