What Is a Pump and Dump? Inside the Memecoin Playbook

How memecoin pumps run stage by stage, why about 94% of suspected pump-and-dump pools appear rugged by their creator, and the checks to run first.

A pump and dump is a coordinated con: insiders hype an asset with false or misleading claims, buyers pile in, and the insiders sell into that demand at the top. The price then drops and late buyers hold the bag. In memecoins it usually ends with the creator pulling the liquidity pool, which is where pump and dump and rug pull become the same trade.

Short version: if the only reason a coin is moving is a tip in a group chat, you are the exit liquidity.

What is a pump and dump, in plain terms?

It is a two-step manipulation: pump the price with hype, then dump your own bag on the buyers that hype pulled in.

The SEC's investor site describes fraudsters who spread false or misleading information to create a buying frenzy, then sell their own shares at the inflated price. The scheme was built for penny stocks. The SEC flags microcaps as easy targets because there is limited public information about microcaps.

Swap "microcap stock" for "token launched an hour ago" and you have the memecoin version. Even less information, even faster tape.

How a memecoin pump and dump runs, stage by stage

The playbook barely changes. What changes is the speed.

The launch. Someone deploys a token and creates the trading pool on a DEX. Hold onto that detail: the address that creates the pool is the address that can usually drain it.

The crowd. Promoters gather buyers in chat rooms and messaging channels. The CFTC notes some of these groups contain thousands of members. The pitch is urgency: a coin about to rip, a signal coming, get in now.

The pump. The signal drops, members buy, the chart goes vertical. That spike is the bait. Outside buyers see green candles and chase.

The dump. Insiders sell into the bid. Per the CFTC, the people pulling the strings get out first, and everyone else scrambles to sell before they lose their money.

The rug. In memecoins the dump often ends with the pool itself getting emptied. Chainalysis found that about 94% of suspected pump-and-dump pools appear rugged by the pool's own creator.

How long does all that take? In the CFTC's example, the cycle was over in under eight minutes. Not days. Minutes.

Pump and dump vs rug pull: what's the difference?

A pump and dump is about price: hype it up, sell into it. A rug pull is about liquidity: the person who controls the pool pulls the money out and leaves holders with tokens nobody can sell.

So the rug pull vs pump and dump question mostly comes down to sequence. The pump draws the buyers. The rug takes their money.

The on-chain signals you can check before buying

You cannot see a group chat, but you can see the chain. Chainalysis turned the pattern into a concrete test.

Its 2023 screen flagged tokens with under $300 of liquidity left, where a single address removed more than 70% of liquidity in one transaction, after five or more earlier DEX purchases. For its 2024 data it loosened the threshold to 65% to catch tokens with bigger pools.

Translate that into a pre-buy checklist:

SignalWhat to checkWhy it matters
Pool creatorWhich address created the DEX poolThat address drained about 94% of suspected pump-and-dump pools
Liquidity controlWhether one address holds most of the poolOne address removing over 70% in a single transaction is the core of the Chainalysis test
Liquidity depthHow much liquidity actually sits in the poolFlagged tokens ended with under $300 left
How you found itA tip, a call, a sudden spikeThe CFTC says don't buy on tips or spikes alone

One caveat Chainalysis itself makes: matching the pattern does not prove a scheme. It is a warning sign, not a verdict. Treat it like a smoke alarm.

How common pump and dumps are in crypto

Common enough that "check before you ape" is the baseline, not paranoia.

For 2024, Chainalysis says 3.59% of launched tokens showed patterns that may be linked to pump-and-dump schemes. Its 2023 analysis put the combined haul for the launchers of flagged Ethereum tokens at about $241.6 million in profit.

Here is the part that matters for your wallet. Per token, the average take was just $2,672 per flagged token, and those tokens were only 1.3% of Ethereum DEX volume in 2023. Each one is a small, quick grab. The model is volume: launch, pump, rug, repeat. You are not watching one big heist. You are watching a production line.

What the regulators say

The SEC describes fraudsters who spread false or misleading information, then sell into the frenzy. The CFTC covers the crypto side: its oversight of spot crypto markets is limited, but it holds general anti-fraud and manipulation authority over them.

Its advice to retail buyers fits in one line: skip tips and sudden price spikes.

Straight answers

How do you tell if a coin is a pump and dump?

Start with how you heard about it. The CFTC's line is blunt: don't buy on social media tips or sudden spikes. Then check the pool: who created it, and whether that address can still pull the liquidity out.

Is a pump and dump the same as a rug pull?

Not quite. A pump and dump is the hype-then-sell cycle; a rug pull is the liquidity getting yanked. In memecoins they usually travel together, with the creator's address pulling the pool after the pump.

Is a pump and dump illegal in crypto?

Regulators treat it as fraud and manipulation. Even where its oversight of spot crypto is limited, the CFTC says it keeps enforcement authority over fraud and manipulation in those markets.

How fast does a pump and dump happen?

Fast. In the CFTC's worked example the whole cycle, from buy signal to the organisers selling out, took under eight minutes. If you are reading about the pump in a chat, you are probably already late.
