Pump and Dump

In Brief
A pump and dump is a scheme where insiders quietly accumulate a token, inflate its price with coordinated hype, then sell their holdings onto latecomers — leaving the buyers who believed the promotion holding a collapsing asset.
What Is a Pump and Dump?
A pump and dump is a market-manipulation scheme in which insiders quietly accumulate an asset, artificially inflate its price through coordinated hype, and then sell their holdings into the buying frenzy they created. The price collapses, and the latecomers who believed the promotion are left holding the losses.
The scheme is old — it predates crypto by a century — but low-liquidity tokens, anonymous teams, and viral social media make crypto markets especially fertile ground for it.
How the Scheme Unfolds
Accumulation: organizers buy a thinly traded token cheaply, often one they created or control.
Promotion: coordinated hype begins — influencer posts, "insider tip" groups, fake news, promises of imminent gains.
The pump: incoming buyers push the price up fast, which itself becomes the marketing.
The dump: organizers sell everything into the demand. Liquidity vanishes, the price craters, and the promoters move on.
Warning Signs
A token you'd never heard of is suddenly everywhere, with urgency ("buying window," "next 100x").
The pitch is price prediction, not product — nobody explains what the token does.
"Signal groups" promise coordinated buys; in practice, the organizers always buy first and sell on you.
Most of the supply sits in a few wallets, or liquidity is thin enough that one seller moves the market.
Pump and Dumps and Trust Wallet
Trust Wallet's Security Scanner helps flag risky tokens and contracts before you sign, and self-custody keeps whatever you hold under your keys. No tool can make a manipulated market safe, though — if the only case for buying is that the price is rising fast, that's the scheme working as designed.
