Centralised vs Decentralised"},"content":{"rendered":"<p>A crypto exchange is a marketplace for buying, selling and trading digital assets. There are two broad types, and the difference matters for how much control \u2014 and risk \u2014 you take on.<\/p>\n<h2>Centralised exchanges (CEXs)<\/h2>\n<p>A centralised exchange is a company that runs the marketplace, holds customer funds, and matches buyers with sellers. They are the easiest on-ramp: you sign up, deposit money from a bank card or transfer, and trade. The trade-off is custody \u2014 while your crypto sits on the exchange, the exchange controls it. &#8220;Not your keys, not your coins&#8221; is the reminder that funds on a platform depend on that platform staying solvent and honest.<\/p>\n<h2>Decentralised exchanges (DEXs)<\/h2>\n<p>A decentralised exchange is software \u2014 smart contracts on a blockchain \u2014 that lets people trade directly from their own wallets, with no company holding funds. You keep custody the whole time. The trade-offs are a steeper learning curve, network fees, and the fact that if you make a mistake there is no support desk to call.<\/p>\n<h2>How to choose<\/h2>\n<ul>\n<li><strong>Custody:<\/strong> a CEX holds your coins; a DEX lets you keep them.<\/li>\n<li><strong>Ease:<\/strong> CEXs are simpler for beginners and for converting cash.<\/li>\n<li><strong>Checks:<\/strong> reputable CEXs require identity verification; DEXs usually do not.<\/li>\n<\/ul>\n<p>Many people use a CEX to buy and a personal wallet to store.
