What Is a Pump and Dump? How to Avoid Falling for a Price Pump
A pump and dump is a scheme where an asset's price is artificially inflated, and then the organizers sell to people who believed the rally. Here's how it works and how not to be the last buyer.
How the scheme works
| Stage | What happens |
|---|---|
| Accumulation | The organizers quietly buy an illiquid asset |
| Pump | Promotion in chats and on social media: "it's about to take off," and the price rises |
| The crowd | Beginners buy on FOMO, and the price speeds up |
| Dump | The organizers sell everything, and the price collapses |
The victims are left holding an asset worth many times less than what they paid. On regulated markets, this is illegal manipulation, but it happens regularly in crypto and small-cap stocks.
Signs of a pump
- A small asset with low liquidity.
- A sharp rise of tens of percent with no news.
- Calls to "get in before it's too late" in chats and channels.
- A spike in volume out of nowhere; more about it in the article trading volume.
How not to fall for it
- Don't buy something you heard about from a promotional "signal" in a chat.
- Don't enter after a vertical rally, even if it feels like you're missing out.
- Always set a stop-loss and calculate your position size.
- Trade liquid assets, where it's hard to pump the price.

Frequently Asked Questions
Can you make money on a pump?
The organizers make money at the expense of those who buy later. A beginner almost always ends up among the last buyers.
How is a pump different from a normal rally?
A normal rally is usually backed by news, earnings reports, and broad demand. A pump is sudden, has no reason behind it, happens in a small asset, and comes with aggressive promotion.
Are pumps legal?
On regulated markets, it's manipulation and is punished. Crypto regulation is weaker, so these schemes are more common there.
