Pump-and-dump schemes: how to spot the pattern on ripr

On ripr, you can spot a pump-and-dump scheme before you buy by checking four things: the shape of the move on the chart, the split between buys and sells, how much of the supply sits in a few wallets, and where the hype reached you. Pump-and-dump schemes all follow one arc. Quiet buying, loud promotion, then a sell-off into the people the promotion brings in — and every phase leaves a mark you can read in two minutes.

What pump-and-dump schemes are, and how they end

A pump-and-dump scheme is a coordinated effort to push a coin's price up with hype and concentrated buying, then sell the supply bought earlier into the new buyers who arrive. It runs in three phases: quiet accumulation, loud promotion once the position is set, and a wave of selling that leaves late buyers holding a coin nothing is bidding on.

It is not the same thing as a rug pull, where the liquidity backing a coin is taken out of its pool. Here the pool stays put and the coin keeps trading; the money just moves from the people who arrived last to the people who were there first. So you are not looking for a broken pool — you are looking at who is buying, who already holds the supply, and where the excitement came from.

Read the move on ripr's chart before you believe it

The first thing to do with a sudden spike on ripr is change the chart's timeframe. Search the coin by name, ticker or its full contract address — the string that identifies it on Solana — and open the chart. Web charts offer eight timeframes from one second to one day, in price, market-cap or volume mode; the iOS and Android apps draw tick through one-day ranges with your entry line and trade markers.

A staged move looks different at different zoom levels. On a one-minute chart it is a wall of green. Step out to six hours or a day and it is usually one near-vertical candle with nothing underneath it: no earlier base, no steady climb.

Now switch the web chart into volume mode. When interest builds on its own, buying thickens gradually. When it is manufactured, nearly all of the volume lands inside the spike itself.

One Solana coin showed the whole arc in a single reading on ripr: up roughly 210% over six hours, with the most recent hour of that stretch already down about 17%. The turn usually starts while the posts are still arriving. That is why the help centre's note on why price moves so quickly on new coins tells you not to chase a sudden spike.

Check who is actually trading the coin

On ripr, a coin's trade feed answers the question the chart cannot: who is actually trading it. Prices, charts and trade feeds update live over a streaming connection rather than on a page refresh, so you can watch the fills arrive one at a time. Volume tells you how much. The feed tells you who.

The tell is a trade count far bigger than the number of wallets behind it, with buys dwarfing sells. On that same coin, ripr's market data put 24 hours of activity at about 8,000 buys against roughly 1,000 sells, made by fewer than 1,000 distinct wallets. That is around nine trades per wallet and eight buys for every sell: a coin being worked rather than found.

ripr's Trending list already leans against that pattern: it ranks coins on how fast trades, volume and distinct buyers are growing, and lowers coins whose activity looks manipulated. Read the split yourself anyway — fast growth tells you where the attention is, not who is behind it.

Check who holds the supply and who launched it

ripr's holders panel on each coin shows what share of the supply the top 10 and top 50 wallets hold and what the creator holds, with pools and vaults left out. That share is the ammunition for the dump. Supply concentrated in a handful of wallets can be sold into your buy order at any moment.

Next, look at how the supply got there. ripr checks coins — including brand-new ones — for coordinated-launch patterns, linked wallets and creators keeping supply, and shows anything it finds as a warning on the coin. A coordinated launch is precisely the set-up this scheme needs: wallets that look unrelated but bought together at the start.

Those warnings appear in the buy flow as well as on the coin page. On iOS and Android the coin page also flags a coin that is under review, has low liquidity or is still being checked, and no coin is ever labelled "safe". To see the raw accounts behind a coin, paste its contract address into explorer.solana.com.

Finally, ripr lists the other coins a creator has launched, so you can read their record yourself. A row of coins that each spiked once and flatlined is as clear a signal as you will get. Our guide to spotting a risky meme coin before you buy walks through the rest of the coin page.

Trace where the hype came from on ripr's feed

Pump-and-dump schemes need an audience, and ripr lets you inspect that audience directly. The app pairs trading with a social feed: you can read a coin's comment thread on its own page, follow traders and open any profile at ripr.trade/. Scroll the thread. Did these accounts post about the coin before it moved, or only after?

Then open a profile. Every ripr account is a Solana wallet, and a profile shows that wallet's holdings and trading results, so you can see whether the loudest voices actually hold what they are promoting.

On iOS and Android, Narratives group coins that share a theme word in their name or ticker and label each theme Hot, Rising or Cooling. A theme turning Hot with a dozen near-identical tickers under it is a crowded trade, not a discovery.

Creators can also livestream about a coin from ripr's apps, with live chat and tips. Streams are part of the fun, but no one can guarantee a market outcome: the help centre's answer to can stream hosts guarantee returns is a flat no. Its advice on how to trade more safely is blunt too: confirm the details on the coin page yourself, and don't copy trade calls from social media.

What to do when a coin is already running

When a coin is already vertical, the practical response on ripr is to slow down and size down:

1. Don't chase the candle. Smaller entries first, and split a larger trade into parts rather than buying the top in one click.
2. Leave Auto slippage on. Slippage is the gap between the price you saw and the price you get; ripr's Auto slippage sets your maximum from how much the coin moved in the last five minutes, between 3% and 15%.
3. Let the app check the transaction. Before your wallet signs, ripr checks the prepared transaction on your device against the amount and slippage you chose, and refuses it if anything differs — so the trade that goes out is the one you set up.
4. Plan the exit before the entry. Drag take-profit and stop-loss lines on a ripr chart and they sell for you while the app is open. Our post on when to sell meme coins and take profits covers the levels.
5. Sell in chunks. When many people sell at once, quotes worsen between preview and execution — the help centre explains why a sell can return less than expected on a drop.

To keep flagged coins out of your lists, turn on "Hide warnings" in Explore and set your own ranges for liquidity, holders and coin age.

Frequently asked questions

Does ripr warn you about a pump-and-dump scheme?

ripr shows rule-based warnings for the patterns these schemes rely on — coordinated launches, linked wallets and a creator keeping supply — on the coin page and in the buy flow, and its Trending list lowers coins whose activity looks manipulated. No coin is labelled "safe", so read the holders panel and the buy and sell counts too.

What is a dump in crypto?

A dump is a fast, concentrated wave of selling that pushes a coin's price down much faster than it went up. In a pump-and-dump scheme the dump is the point of the exercise: the wallets that accumulated early sell into the buyers the hype attracted.

Can you make money buying into a pump and dump?

Some early wallets do, but they bought before the promotion started, and a buyer arriving on the spike is the exit they are selling into. If you take the trade anyway, risk only money you can afford to lose and set your exit levels before you buy.

How long does a pump and dump last?

On small coins the whole arc often plays out within hours, and the fall can be quicker than the rise. On ripr you can watch it at the resolution it happens: one-second candles on web and a live tick view on iOS and Android cover the most recent minutes of the move.

The habit that protects you

A pump-and-dump scheme only works on someone who buys the story instead of the coin. So open the coin page on ripr, zoom the chart out, read the trade split and the holders panel. Give yourself the two minutes the promotion is trying to take away.
