AMM algorithms power decentralized exchanges by using mathematical formulas to set prices based on token reserves in liquidity pools. Learn how Uniswap, Curve, and Balancer calculate prices, handle slippage, and evolve with new models like concentrated liquidity and dynamic fees.
Liquidity Pools Explained: How They Work and Why They Matter in Crypto
When you trade crypto on a decentralized exchange like Uniswap or SushiSwap, you're not buying from another person—you're trading against a liquidity pool, a smart contract that holds paired tokens to enable instant trades without order books. Also known as automated market makers, these pools are the backbone of modern DeFi. Without them, you’d need to wait for someone to match your buy or sell order. With them, trades happen in seconds, even for obscure tokens.
Liquidity pools don’t just make trading possible—they shape token value. If a token has a small pool with little money in it, even a modest trade can crash its price. That’s why you see posts about Perezoso (PRZS), a meme coin with almost no trading volume and dangerously low liquidity, or DexKit (KIT), a token tied to a platform struggling to attract enough users to sustain its pool. Low liquidity isn’t just inconvenient—it’s a red flag. It means slippage, high risk, and the chance your investment could vanish if no one else is buying.
But not all liquidity pools are risky. Some are deeply funded, like those backing Bitcoin or Ethereum on major DEXs. These offer stability. Others, like the ones behind wrapped assets, tokens that represent real crypto on other blockchains, are built to move value across chains and unlock new uses. These pools help connect Bitcoin to DeFi, or Solana tokens to Ethereum-based lending. But they also introduce complexity—what if the bridge breaks? What if the underlying token loses value? That’s why understanding how liquidity works matters more than ever.
Behind every low-volume token you read about—whether it’s Birb (BIRB), a confusing meme coin with multiple versions on different chains, or PumaPay (PMA), a failed payment protocol now worth almost nothing—there’s a liquidity pool that either never grew or collapsed. The same goes for airdrops like CHY, a token with $0 value and zero trading activity. If no one puts money in, the pool is empty. And an empty pool means no one can trade. No one cares. And the token dies.
It’s not just about how much is in the pool—it’s about who put it there, why, and how long they plan to stay. Smart liquidity providers earn fees, but they also risk impermanent loss. If one token in the pair spikes or crashes, they can lose money even if the overall value goes up. That’s why most retail traders avoid providing liquidity—and why the posts you’ll find here focus on the tokens that are being traded, not the ones being supplied.
What you’ll see below isn’t a list of how to build a pool. It’s a catalog of real-world failures, scams, and barely-alive projects where liquidity either never arrived or disappeared overnight. You’ll learn why some tokens are traps, why others still have a pulse, and how to spot the difference before you invest. This isn’t theory. It’s what’s happening right now—in every low-volume trade, every abandoned pool, every ghost chain.
