What Are Centralized Exchanges (CEX) And How Do They Work?

Crypto traders usually operate on different platforms depending on their financial approaches and goals. Today we’ll discuss centralized exchanges, or CEXs, and try to find out what they are, how they work, and whether it's a good idea to use them for crypto trading.

What Is A Centralized Exchange?

A centralized exchange is a digital platform where users can buy, sell, and trade cryptocurrencies; in other words, CEX is an intermediary that facilitates the transactions. Operated by a company or organization, a centralized exchange manages users' funds, maintains order books, and ensures liquidity by matching buy and sell orders.

Centralized exchanges offer a wide range of trading pairs, advanced tools, and customer support, making them popular choices for both novice and experienced traders. However, they also pose risks such as potential hacks, regulatory scrutiny, and the possibility of the exchange acting as a single point of failure, which has led some users to prefer decentralized alternatives for greater control over their assets.

How Does CEX Work?

To understand how CEX works, it’s essential to learn the following aspects that describe the main principles of such exchanges work:

1. Account creation and verification: users start by registering on the exchange platform, providing essential details like an email address and password. Most CEXs require completing a Know Your Customer (KYC) process, which involves submitting identification documents and sometimes additional personal information to verify identity. Once registered, users can deposit funds into their exchange accounts.

2. Order placement and matching: users can place different types of orders, such as market(executed immediately at the current price) or limit orders (executed at a specified price). The exchange maintains a special book listing all active buy and sell orders. A matching engine within the CEX automatically pairs compatible orders based on price and time priority, facilitating trade execution.

3. Holding and security of funds: CEX holds users’ funds in its wallets. Advanced security measures, including encryption, two-factor authentication (2FA), and regular security audits, are implemented to protect user assets from hacks and unauthorized access.

4. Trading features and tools: centralized exchanges offer different products, such as P2P trading and staking, as well as auxiliary trading tools such as charts and technical analysis. Additionally, CEXs may provide liquidity and market-making services to ensure smooth and efficient trading.

5. Fees and revenue model: CEXs generate revenue through various commissions, including trading fees (a percentage of each transaction), withdrawal or listing fees for new cryptocurrencies, and sometimes charges for additional services like margin trading. These figures can vary based on the user’s trading volume and membership tier within the exchange.

By centralizing these functions, CEXs create a user-friendly and efficient environment for cryptocurrency trading, leveraging their infrastructure to offer liquidity, diverse trading options, and robust security measures. Users must trust the exchange to manage their funds securely and comply with relevant regulations, making the choice of reputable and well-established CEXs essential.

Not all coins can be traded on centralized exchanges, but only those that are listed on it. CEX listing is the process by which a cryptocurrency or token is officially added to a centralized exchange, enabling it to be bought, sold, and traded by its user base. This inclusion is a significant milestone for blockchain projects as it enhances the token’s visibility, accessibility, and liquidity within the broader cryptocurrency market.

Pros And Cons Of CEX

Centralized exchanges play a pivotal role in the cryptocurrency ecosystem, offering various advantages and facing certain drawbacks. Understanding the pros and cons of CEXs can help users make informed decisions about where to trade and store their digital assets.

Pros of CEX

Let’s look into the advantages of using CEXs:

1. User-friendly interface. CEXs typically feature intuitive interfaces that cater to both beginners and experienced traders, making the trading process straightforward. They often provide extensive customer support, including tutorials, FAQs, and responsive help desks to assist users with any issues.

2. High liquidity. CEXs usually have large user bases, ensuring high liquidity. This means users can execute large trades without significantly affecting the market price. High liquidity leads to faster order matching and execution, reducing the time it takes to complete transactions.

3. Wide range of trading pairs. CEXs offer a vast selection of cryptocurrencies and trading pairs, allowing users to diversify their portfolios easily. They also often list newly launched tokens promptly, providing traders with early access to emerging projects.

4. Advanced trading features. CEXs provide sophisticated trading tools, including charting software, technical indicators, and automated trading options. Many CEXs offer margin trading and leverage options, enabling users to amplify their trading positions.

5. Security measures. Reputable CEXs implement strong security protocols, such as encryption, two-factor authentication (2FA), and cold storage solutions to safeguard user funds. Some exchanges even maintain insurance funds to compensate users in the event of a security breach or hack.

6. Regulatory compliance. CEXs adhere to regulatory standards, including Know Your Customer (KYC) and Anti-Money Laundering (AML) policies, which can enhance user trust and platform legitimacy. Some exchanges are also audited by CERTIC, which additionally enhances platform projects’ security. For example, Cryptomus is among them. Compliance with regulations can facilitate smoother operations and reduce the risk of legal issues that might disrupt services.

Cons of CEX

However CEXs also have disadvantages too. Let’s see:

1. Custodial nature. Users deposit their funds into the exchange’s wallets, relinquishing direct control over their assets. There is a risk that the unscrupulous or inexperienced exchange could mismanage funds or become insolvent, leading to a potential loss of user assets.

2. Security risks. Due to holding large amounts of user funds, CEXs are attractive targets for hackers. Centralization means that any security flaw or attack can compromise the entire platform, and If there is a service disruption, CEX may be hacked that would result in significant losses for users.

3. Regulatory vulnerability. CEXs are subject to governmental regulations and can be shut down or restricted by authorities, potentially limiting user access to funds and services. That’s why centralized exchanges require you to verify your identity to comply with AML (anti-money laundering) and KYC policy which are required by the regulation.

4. Fees and costs. CEXs typically charge various fees, including commissions for trading, withdrawals, and sometimes depositing, which can add up, especially for high-frequency traders. Some fees may not be transparent, making it difficult for users to understand the total cost of their transactions.

5. Downtime and technical issues. CEXs can experience downtime due to maintenance, high traffic, or technical glitches, preventing users from accessing their accounts or executing trades when needed. Thus, users might face delays in withdrawing their funds during high demand or technical problems.

CEX VS DEX

For your comfort, we’ve prepared a table describing centralized and decentralized exchanges. It highlights their key differences across various aspects to help you understand their distinct features, advantages, and drawbacks.

Decentralized Exchange (DEX)	Characteristics - Users retain full control of their funds through personal wallets. - Enhanced security as funds are stored in user-controlled wallets; lower risk of centralized hacks. - Often lower liquidity, though improving with advancements like automated market makers (AMMs). - Interfaces can be less intuitive; limited customer support. - Typically less regulated, offering greater privacy but potential legal uncertainties. - Often lower fees, primarily limited to transaction fees. - Slower trade execution, dependent on blockchain network speed. - Greater anonymity, as they often do not require personal information. - Limited advanced features; primarily focuses on spot trading. - Minimal custodial risk as users control their own assets. - Slower updates, reliant on community consensus. - Less prone to manipulation due to decentralized order books and transparency. - Greater interoperability with various blockchains and tokens via smart contracts. - Users are responsible for their own security, with no custodial insurance. - Access to new tokens may be delayed or require manual configuration by users. - Governed by decentralized protocols and community voting mechanisms. </br>

So, your choice between a CEX and a DEX should depend on your individual needs and priorities:

Choose a CEX if you:

• Prefer a simple and intuitive trading interface.
• Require high liquidity for large trades.
• Value customer support and advanced trading tools.
• Are comfortable with sharing personal information for compliance.

Choose a DEX if you:
