<p>Centralized Exchanges (CEXs) are traditional cryptocurrency trading platforms that facilitate transactions between buyers and sellers through an order book. They are the most common type of crypto exchange and are often the first point of entry for new cryptocurrency traders.</p>

<h2>How It Works</h2>
<p>CEXs work by matching buy and sell orders from users. Here's a simplified explanation:</p>
<ul>
  <li><strong>Order Book</strong>: A CEX maintains an order book, which is a digital record of all the buy and sell orders for a particular cryptocurrency. This includes the price at which the user is willing to buy or sell, and the quantity of the cryptocurrency they want to trade.</li>
  <li><strong>Matching Orders</strong>: When a buy order matches a sell order at the same price, the trade is executed, and the cryptocurrency is exchanged between the two users.</li>
  <li><strong>Fees</strong>: CEXs generate revenue by charging fees for each trade, usually a percentage of the total trade value.</li>
</ul>

<h2>Why It Matters</h2>
<p>CEXs matter for several reasons:</p>
<ul>
  <li><strong>Liquidity</strong>: CEXs often have high liquidity, meaning there are many buyers and sellers active on the platform. This makes it easier to trade large amounts of cryptocurrency without significantly affecting the price.</li>
  <li><strong>Regulation and Security</strong>: CEXs are typically regulated by financial authorities, which can provide users with a level of protection. They also often have robust security measures in place to protect user funds.</li>
  <li><strong>Ease of Use</strong>: CEXs are usually designed with user experience in mind, making them a good choice for beginners. They often support a wide range of cryptocurrencies and trading pairs.</li>
