Spot a Pump-and-Dump
Why small coins jump 200% and then crash, and how to see it coming
What Is a Pump-and-Dump?
A pump-and-dump is when a group buys a coin cheaply, drives the price up with hype, and sells to the people who buy late. It works best on coins with low volume, because a little money moves the price a lot.
A small group buys a thinly traded coin cheaply while nobody is watching. Volume is low, so they can build a big position without moving the price much.
Posts, group chats and paid promotions start talking about the coin: a partnership, a listing, "the next 100x". The story matters more than whether it is true.
New buyers pile in and the price shoots up, often tens or hundreds of percent in a day. Each green candle attracts more buyers who are afraid of missing out.
The early group sells into that demand. With little real volume underneath, the price falls fast, and late buyers are left holding a coin worth a fraction of what they paid.
A rug pull is the harsher version: the team behind a token sells its own large holdings or removes the liquidity, and the price can drop 90% or more within minutes.
The Warning Signs (and What Our Badge Checks)
Every coin page shows a risk level: Low, Elevated, High or Extreme. It is the worst of the signals below, and three or more High signals together count as Extreme. Tap the badge to see which signals fired and the numbers behind them.
With little volume, one large order can move the price a lot, and you may not be able to sell at the price on screen.
Under $100K traded in 24 hours is Elevated, under $10K High, under $1K Extreme.
Moves this large and this fast are usually driven by hype or a few big buyers, and they often reverse.
+25% or -25% in 24 hours is Elevated, +50% or -40% High, +100% Extreme. Over 7 days: +50% / -40%, +100% / -60%, +200%.
This is the shape a pump-and-dump leaves on the chart: a fast run-up, then a slide as early holders sell.
Rose at least 50% within a week, then gave back at least 30% from the peak (30% and 20% for Elevated).
Bigger swings mean bigger losses as well as gains, and position sizes that are fine for BTC are too large here.
Typical daily move over the last 30 days at least 3× Bitcoin's (Elevated) or 5× (High).
New listings are often the most volatile and have no track record. Many pumps happen in the first days of trading.
Under 30 days of price history is Elevated, under 7 days High.
They rebalance every day, so in a market that goes up and down their value decays, even if the price ends where it started. They are built for short holds.
Names like NEAR5S, BTC3L or ETHUP: tokens that aim for 3× or 5× the daily move of another coin. Always High.
A stablecoin that loses its peg can keep falling if holders rush to exit.
A dollar stablecoin trading 0.5% away from $1 is Elevated, 2% High, 10% Extreme.
New buys are disabled. You can still sell what you hold.
The coin has been delisted on CoinSparring. Always Extreme.
Before You Buy a Coin That's Flying
- Look at 24h volume before the price. A big percentage on a tiny volume is easy to fake and hard to exit.
- Ask why it moved. If you can't find a reason beyond posts telling you to buy, treat the move as hype.
- Don't chase a candle that is already up 50%+. If you do buy, use a small position and set a stop-loss first.
- Check the chart for the spike-then-fade shape and how long the coin has been trading.
- Never put more into a small coin than you can afford to see go to zero. On CoinSparring that money is practice money; build the habit now.
Common questions
What is a pump and dump in crypto?
- A scheme where a group buys a thinly traded coin cheaply, drives the price up with hype, then sells to the people who buy late. The price usually collapses once they have sold.
How do crypto pump-and-dump schemes work?
- In four stages: quiet buying while volume is low, a burst of hype in posts and group chats, a fast price spike as new buyers pile in, and the dump, when the early group sells into that demand and the price falls.
What does a pump and dump look like on a chart?
- A sharp run-up on a coin with little trading volume, often tens or hundreds of percent within a day or a week, followed by a slide as the early holders sell. CoinSparring's risk badge flags that spike-then-fade shape, thin volume and extreme moves on every coin.
