What Is a CEX Exchange and How Does It Work?

Main Features of Centralized Exchanges (CEX) 

Centralized crypto exchanges are in high demand among traders. Binance alone has about 250 million registered accounts, and daily trading volume reaches tens of billions of dollars. 

To help you understand what a CEX exchange is and how it works, we have prepared an analysis of its key features: 

Centralized management 

CEX platforms are controlled by specific companies that regulate everything, from registering users to processing financial transactions. This makes exchanges more structured and convenient but requires trust in the administration, which is responsible for asset custody, order execution, and security. 

Ease of use 

One of the main pros of CEX exchanges is their intuitive interface. Even a beginner can easily create an account, deposit a balance, and start trading. Most CEX platforms offer mobile apps, 24/7 technical support, training, and various market research tools. 

High liquidity 

CEX exchanges process thousands of transactions daily, positively affecting liquidity and allowing users to buy and sell crypto quickly without significant price fluctuations. 

Additional features 

In addition to spot trading (transactions that involve full payment and actual delivery of assets), centralized exchanges offer advanced functionality: 

• Margin trading — the ability to borrow funds from the exchange to open trades for larger amounts to increase potential profits. 

• Futures and options are instruments for trading on price forecasts without actually purchasing assets. 

• Staking is a way to generate passive income from holding tokens and coins. 

• Lending opens up the possibility of lending cryptocurrency to other users and earning interest for its use. 

Storage of funds online and offline 

Hot wallets are used to process transactions quickly and require an internet connection. Usually, these vaults hold a small portion of assets due to the risk of cyberattacks. 

Cold wallets operate without the internet and provide maximum protection from hacks. Major crypto exchanges, such as Kraken, Binance, and WhiteBIT, store up to 95% of users’ assets in offline vaults. 

Multi-signature 

This is a mechanism where multiple digital signatures are required to validate a transaction. CEX exchanges use it to reduce the risk of unauthorized withdrawals. 

Advantages of CEX (Centralized Exchanges) 

Liquidity, convenience, and various trading features are key advantages of CEX venues, but not the only ones. The list of upsides also includes: 

• Integration with traditional finance. The ability to work with fiat currencies simplifies deposits and withdrawals. 

• Speed of operation. Transactions are processed in seconds thanks to the powerful server system CEX exchanges use. 

• Mandatory verification. The identity verification procedure increases trust and makes transactions more transparent. 

• Reliable infrastructure. Centralized management allows for quick response to changes and regular security updates. 

• Insurance. Some major CEX exchanges provide guarantees to protect users. For example, Binance has set up a special reserve fund to compensate for financial losses in case of cyberattacks or unforeseen situations. 

Disadvantages of CEX Exchanges 

Let’s consider the main disadvantages and risks of interacting with centralized platforms: 

• Limited capital control. Storing crypto assets on hot exchange wallets makes users dependent on the reliability of platforms. In case of technical failures or account freezing, you could temporarily lose access to assets. 

• Security risks. CEX platforms are often targeted by cybercriminals. For example, in February 2025, the Bybit exchange suffered the largest cyberattack in the history of cryptocurrencies, where hackers stole $1.5 billion in digital assets. 

• Regulatory restrictions. A CEX exchange is required to comply with laws and regulations, which may limit the availability of services for some users. 

• Commissions. Exchanges charge fees for trading and withdrawals, which may be higher compared to other services. 

What Is the Difference Between a Centralized Exchange (CEX) and a Decentralized Exchange (DEX)? 

DEX (Decentralized Exchange) are crypto exchanges that operate on the blockchain without a central authority. Here, transactions are made through smart contracts (algorithms that execute crypto transactions according to set conditions). Popular DEXs are Uniswap and PancakeSwap. 

Before you start trading cryptocurrencies, it is important to understand the difference between a centralized exchange and a decentralized one. Let’s consider the main criteria: 

Anonymity and registration 

CEX platforms almost always require uploading photo documents and confirming your phone number. DEXs do not ask for data: it is enough to connect a cryptocurrency wallet (e.g., MetaMask), and you can trade under a pseudonym. 

Storage of funds 

On CEX, you entrust funds to the exchange, which stores them in its wallets. On DEX, users manage their personal wallets, and transactions take place through the blockchain. The responsibility for security rests solely with you.  

Liquidity and speed 

A centralized exchange allows you to instantly execute transactions at market prices, while on DEX exchanges, the situation depends on pools — reserves of tokens, which users add. For rare coins, the spread (the difference between the buy and sell price) can be significant, and transactions are slow. 

Interface and functionality 

CEXs offer convenient service and support, while DEXs often have a minimalistic design and are aimed at experienced traders. To make a trade, you need to understand commission settings (gas), wallet connectivity, and the risks of smart contracts. 

Is It Worth Using CEX Exchanges? 

CEXs are a convenient start for beginners: they are fast and clear and offer help with problems that arise during the trading process. If you are just starting to understand crypto and value comfort, centralized exchanges will suit you. However, you should keep in mind the risks: your money is stored with the company, and in case of technical failure or hacking, you can lose it. You should use CEX if you are ready to trust the platform and are not looking for complete anonymity. The main thing is to choose trusted exchanges with a good reputation and not keep all your savings there. 

Conclusion 

Centralized cryptocurrency exchanges offer convenient trading conditions, providing high liquidity and availability of various trading instruments. However, like any other service, CEX platforms have disadvantages related to the security of asset storage and dependence on the organizations that control them.   

To sum up, a centralized exchange is a convenient but cautious choice for those who value comfort and efficiency and are willing to manage risk.
