Pump Group
A coordinated private group — typically on Telegram or Discord — that secretly accumulates a low-value cryptocurrency then simultaneously promotes it to inflate the price before selling at a profit, leaving later buyers at a loss.
Also known as: crypto pump group, pump-and-dump group, pump signal group

A pump group is an organised collective that coordinates cryptocurrency price manipulation. The group, usually numbering dozens to thousands of members, identifies a low-liquidity token, accumulates positions quietly, then sends a simultaneous 'buy signal' to all members. This sudden burst of coordinated buying artificially inflates the token's price and trading volume, attracting external buyers who see the spike and assume there is genuine momentum.
Group organisers — who hold the largest positions and bought earliest — sell into the rising price, a practice called 'dumping'. Rank-and-file group members may also profit if they react quickly enough. However, most external buyers who see the spike on price charts and pile in after the signal are left holding tokens at inflated prices when organisers dump their holdings, causing the price to collapse.
Pump groups operate openly in messaging apps, advertise their 'signals', and target newer investors unfamiliar with pump-and-dump dynamics. Some groups even charge membership fees or sell 'premium' early signals, adding an additional revenue stream for organisers. Pump-and-dump schemes are illegal in regulated securities markets; their legal status for unregistered cryptocurrencies varies by jurisdiction, though regulators globally are increasingly treating coordinated crypto manipulation as market abuse.
Examples
- A Telegram group of 10,000 members announces a 'buy signal' for an obscure token at a set time; the coordinated purchase spikes the price 300%, the organisers sell their holdings, and the price crashes within minutes leaving most participants at a loss.
