In short
A pump group is a chat where members agree to buy the same token at an announced time to drive the price up. The organisers, who bought earlier, sell into that buying; the members who arrive late take the loss. Coordinated price manipulation is potentially illegal, and joining one does not put you outside that.
Key points
- Members buy the same token at an announced time
- Organisers accumulate first and sell into the rush
- Late buyers absorb the losses by design
- Coordinated manipulation is potentially illegal for participants too
Definition
A chat group organised so that members buy a chosen token simultaneously at a set time, spiking its price, with the intention of selling into the move.
The format is consistent. The ticker is withheld and only a start time announced; at the appointed moment the name is released and members buy at market; the price spikes within minutes and then collapses, leaving a narrow spike on the chart.
Only those who bought before the announcement profit. Organisers and senior members accumulate in advance and sell into the wave. Some groups sell tiers that receive the ticker seconds early — a design that assumes later buyers must lose.
The legal position matters. Japan's Financial Instruments and Exchange Act prohibits trading intended to move prices and the spreading of rumours, and unfair trading in crypto assets is covered under the framework combining that act with the Payment Services Act. Organisers are not the only ones exposed; knowingly joining can be a problem too. Declining the invitation is the only safe response.
Watch out for
- · 'We'll tell you the next ticker' is recruitment for buyers, nothing more
- · By the moment the price spikes, the selling has already started
- · Taking part in manipulation can carry legal liability in Japan
