## Why Do Centralized Exchanges (CEX) Often Have Tighter Spreads for Altcoins than Decentralized Exchanges (DEX)?

CEXs use a traditional, high-speed, off-chain order book model that attracts professional, competitive market makers who actively quote tight spreads to capture flow. DEXs, however, primarily use Automated Market Makers (AMM) and liquidity pools.

DEX transactions incur variable, on-chain gas fees and are prone to higher slippage due to the AMM formula, making the effective cost and spread generally wider than on a CEX.
