Chapter 1: Introduction to CEXs

When discussing cryptocurrencies, the term "CEX" refers to a "Centralized Exchange." These online platforms serve as marketplaces that simplify the buying, selling, and trading of various cryptocurrencies. Acting as intermediaries, CEXs facilitate transactions between buyers and sellers by providing user-friendly interfaces and order matching services.

Typically, centralized exchanges function as follows:

1. User Registration: To begin using a CEX, individuals must register by providing personal details and, in many cases, completing a Know Your Customer (KYC) verification process. This process is crucial for compliance with legal requirements and to prevent illicit activities such as money laundering.
2. Deposits: Once registered, users can deposit funds into their exchange wallets, which can be in the form of cryptocurrencies or fiat currencies (e.g., USD, EUR). Each user receives a unique wallet address for each supported cryptocurrency.
3. Order Entry: After funding their accounts, users can place various types of orders on the exchange. The most common types are "market orders" (buy/sell at the current market price) and "limit orders" (set a specific price at which to buy or sell). Some exchanges also offer advanced order types, such as "stop-loss" and "take-profit."
4. Order Matching: The exchange's system pairs buy and sell orders based on the specified price and other market factors. A transaction occurs when the price of a buy order meets or exceeds the price of a sell order.
5. Execution and Fees: Upon the completion of a transaction, the corresponding digital assets or funds are credited to the user’s accounts. The exchange charges fees for transactions, which may include trading fees, withdrawal fees, and other additional charges.
6. Security: Centralized exchanges hold user funds in wallets, necessitating robust security measures to protect against hacks and breaches. Established exchanges implement various security protocols, including two-factor authentication (2FA), cold storage for most of their assets, and continuous monitoring for suspicious activities.
7. Withdrawals: Users have the option to withdraw their cryptocurrency or fiat funds at any time, adhering to the platform's withdrawal policies.

While CEXs offer convenience and user-friendly experiences, it's essential to recognize their drawbacks. Unlike decentralized exchanges (DEXs), CEXs store user funds in centralized wallets, which can make them more susceptible to hacking. Users must place their trust in the exchange's ability to safeguard their assets, which can be concerning if the platform is untrustworthy or poorly managed. To minimize risk, users should opt for reputable exchanges known for their security and reliability.
