In simple terms, a Centralized Exchange, or CEX, is like the headquarters of trading in the crypto world. It’s a platform where you can buy, sell, and trade various cryptocurrencies. Think of it as a big marketplace where you can find a variety of digital assets. Unlike decentralized exchanges, CEXs are run by a central authority, making them more like traditional stock exchanges. Users trust these platforms to facilitate their transactions securely. 

This comprehensive guide offers insight into CEX trading platforms and answers the question, “What is CEX?” while giving beginners new to trading cryptocurrencies or those seeking in-depth knowledge a unique insight.

History of CEXs

Centralized Exchanges (CEXs) emerged in response to the growing demand for a platform to facilitate cryptocurrency trading efficiently. In the early years of cryptocurrencies like Bitcoin, there was a need for a centralized hub where users could easily buy and sell digital assets.

Platforms like Mt. Gox, established in 2010, played a pioneering role. However, these early exchanges faced security issues, with it famously experiencing a major hack in 2014.

Despite setbacks, newer CEXs like Coinbase and Binance entered the scene, learning from past mistakes and implementing robust security measures. Over time, CEXs became essential in making cryptocurrency trading more accessible to a broader audience, contributing to the overall growth of the crypto market.

In order to answer the question “What is CEX?”, it would be better to have a brief look at the history of its formation first. Now, let’s talk about how it works.

How Does a CEX Work?

Users place buy or sell orders on the CEX platform, specifying the desired quantity and price. The CEX then matches these orders, executing trades between buyers and sellers. It is important to mention that sometimes the deals are done quickly. This centralized model provides a streamlined and user-friendly environment for cryptocurrency trading, with the exchange managing the order book, order matching, and transaction settlement. Security measures are implemented to ensure the integrity and confidentiality of user data and assets, making CEXs a trusted avenue for participants in the crypto market. It’s good to mention that the transaction speed in CEXs is lower compared to a DEX because in CEXs, you need to wait for the intermediary’s approval.

Several steps for using a Centralized Exchange 

Account Creation 

Begin by creating an account on the CEX platform. This typically involves providing necessary details, undergoing identity verification, and setting up security features like two-factor authentication.

Deposit Funds 

Once the account is set up, deposit funds into your exchange wallet. This can often be done using various methods such as bank transfers, credit/debit cards, or other accepted payment methods.

Navigate the Platform

Familiarize yourself with the CEX platform. Most of them have an intuitive interface with sections for buying, selling, and managing your portfolio.

Placing Orders

When you’re ready to trade, you can place different types of orders. A “market order” is executed immediately at the current market price, while a “limit order” allows you to specify the price at which you want to buy or sell, waiting for the market to reach that point.

Monitoring Orders

Keep an eye on your open orders and transaction history. The platform provides real-time updates on your trades and account balance.


If you wish to move your assets to an external wallet for added security, you can initiate a withdrawal. This involves specifying the amount and providing the destination wallet address.

Security Measures

It’s crucial to implement security measures such as two-factor authentication to enhance the safety of your account.

Stay Informed 

Keep yourself informed about market trends, news, and any updates from the CEX. This knowledge can aid in making informed trading decisions.

Choose a platform with an intuitive and user-friendly interface, making navigating and executing trades easy. Ensure that the trading features are accessible and suit your level of expertise.

Supported Cryptocurrencies

Higher liquidity often results in better trade execution. Choose an exchange with a good trading volume for your preferred assets.

Fees and Costs

Understand the exchange’s fee structure, including trading, withdrawal, and other associated fees and costs. Some exchanges offer fee discounts or loyalty programs based on trading volume.

Payment Methods

Ensure that the exchange supports deposit and withdrawal methods that are convenient for you, such as bank transfers, credit/debit cards, or other payment options.

Regulatory Compliance

Verify that the exchange complies with relevant regulations in your area. This adds an extra layer of trust and legal protection.

Customer Support

Check the availability and responsiveness of customer support. A reliable support system can be crucial in case of issues or inquiries.

Confirm whether there are any geographical restrictions imposed by the exchange, ensuring that you are eligible to use the platform in your location.

Disadvantages of Centralized Exchanges

Security Risks

CEXs are susceptible to security breaches and hacking attempts. In the past, some exchanges have experienced significant security incidents, leading to the loss of user funds.

Custodial Control

Users must entrust their funds to the exchange, which is a custodian. This centralized control goes against the decentralized nature of cryptocurrencies, and in the event of an exchange’s failure, users may face financial losses.

Limited Privacy

CEXs often require users to undergo identity verification processes, compromising user privacy. Personal information can be vulnerable to data breaches.

Regulatory Dependencies

Centralized Exchanges are subject to regulatory requirements, and regulation changes can impact their operations. Users may face restrictions or additional compliance procedures.

Potential Downtime

CEXs can experience technical issues or downtime, preventing users from executing trades or accessing their funds during crucial market movements.

Lack of Control

Users do not have direct control over their private keys when using CEXs. This lack of control contrasts with the principles of self-custody advocated in the cryptocurrency space.


Centralized Exchanges often charge fees for trading, withdrawals, and other services. These fees can accumulate, affecting the overall profitability of trading activities.

Limited Access

Some CEXs have geographic restrictions, limiting access to users from specific regions. This can be a barrier for individuals in areas with limited crypto infrastructure.

Single Point of Failure

CEXs are a risk in the cryptocurrency world. If something really bad happens to an exchange, it can cause problems for lots of users and the whole market.

Counterparty Risk

Users face counterparty risk when trading on CEXs, relying on the exchange to fulfill orders. Issues such as insolvency or mismanagement can result in financial losses.
