Pump and Dump

A pump and dump is a manipulation scheme in which organizers accumulate a cheap, thinly traded asset, artificially inflate its price through coordinated buying and hype (the pump), and then sell their holdings onto the buyers they attracted (the dump), crashing the price.

A typical example: a group quietly buys a low-liquidity altcoin, then floods social media channels with claims of imminent listings or partnerships. Latecomers see the price rocketing and buy in fear of missing out. The organizers, who bought far lower, sell into that demand; the price collapses within minutes or hours, and the late buyers hold losses that rarely recover.

Pump and dumps thrive on small-cap tokens because tiny liquidity means little money is needed to move the price dramatically. Some schemes are run openly through group chats whose ordinary members are, in reality, the exit liquidity for insiders who receive earlier signals. The practice is illegal in regulated securities markets and increasingly prosecuted in crypto. Warning signs include sudden parabolic moves in obscure tokens, anonymous teams, coordinated identical shilling, and urgency-driven messaging. A common misconception is that joining early makes a pump profitable for you; the organizers' entire design is that outsiders, whenever they enter, are the ones left holding.
