How a pump and dump works
- Accumulate quietly. Organisers buy a low-liquidity coin, where a modest amount of money moves price a lot.
- Pump. They push price up fast, often while promoting the coin in groups, channels or social posts that promise “the next 10×”.
- Dump. As late buyers rush in, the organisers sell into that demand. Price collapses, often below where the pump started, and the late buyers hold the losses.
Coordinated schemes like this are market manipulation and are illegal in many jurisdictions. Even where crypto rules are unclear, the arithmetic is the same: the people who arrive late fund the people who left early.
Warning signs
| Signal | Pump and dump | Healthy breakout |
|---|---|---|
| Price action | Near-vertical candles with long upper wicks | Steps up, holds retests |
| Volume | From almost nothing to extreme in minutes | Rises over hours or days |
| Liquidity | Thin order book, small daily dollar volume | Deep book, consistent volume |
| Open interest | Spikes late, as leveraged longs chase | Builds steadily with price |
| Funding | Jumps to extreme positive levels | Moderate |
| News | None, or vague hype and screenshots | A clear catalyst, or none needed |
What it looks like in futures data
On perpetual futures, the late stage of a pump has a clear signature: price is already far up, funding turns sharply positive as longs pay up to stay in, and open interest jumps as leveraged buyers pile in. When the organisers sell, those late longs are liquidated, which turns the dump into a cascade. That is why the drop is usually faster than the rise.
Example (illustrative): a small coin rises 45% in two hours on volume 30 times its average. Funding goes from +0.01% to +0.4% per interval and OI doubles in the final hour. Within a day price gives back the whole move, and OI falls by more than half as longs are liquidated.
How to protect yourself
- Don’t chase vertical candles. If you missed the move, the risk is now on the downside.
- Check liquidity first. Small daily dollar volume means a few players can move price both ways.
- Ignore “pump group” calls. Anyone announcing a pump in advance needs buyers to sell to.
- Watch funding and OI. Extreme funding plus late OI spikes mean the move is crowded and fragile.
- Size small and use a stop. Dumps gap through levels quickly, and leverage magnifies them.
Telling new money from a pump
A move backed by steady open interest growth is different from one where OI appears only at the top. The which coin will pump today board lists coins where price and OI are rising together. To flag overheated moves instead, scan for:
Overheated: be careful
A huge short-term move, longs paying a heavy premium and volume far above normal. Classic late-pump conditions.
Frequently asked questions
What is a pump and dump in crypto?
A scheme where organisers buy a low-liquidity coin, push its price up with buying and hype, then sell to the late buyers they attracted, so price collapses.
Are crypto pump and dumps illegal?
Coordinated price manipulation is illegal in many jurisdictions. Rules for crypto vary by country, but participants who buy late almost always lose money either way.
How can I tell a pump from a real breakout?
Real breakouts build over time with steady volume, rising open interest and moderate funding, and they hold retests. Pumps are vertical, come from thin liquidity, and show extreme funding and late OI spikes.
Can you make money from a pump and dump?
The organisers usually do; late participants usually don’t. Trying to time the top of someone else’s pump is one of the riskiest trades in crypto.
