Exchange
A cryptocurrency exchange is a platform that allows users to buy, sell, and trade digital assets such as Bitcoin, Ethereum, and altcoins. Exchanges come in two forms: centralised (CEX), like Binance or Coinbase, and decentralised (DEX), like Uniswap. Centralised exchanges offer user-friendly interfaces, high liquidity, and customer support but require identity verification (KYC). DEXs offer more privacy and control over funds, operating through smart contracts. Exchanges also offer tools for portfolio tracking, market analysis, and margin trading. Choosing the right exchange depends on factors like security, fees, and available assets.
