An exchange is a platform that provides users with the means to buy and sell digital assets in the cryptocurrency market. There are two types of exchanges: Centralized Exchanges (CEX) and Decentralized Exchanges (DEX). Understanding how these two types of exchanges operate, as well as their advantages and disadvantages, will help you make the most appropriate decision for your trading needs. Let’s explore more in the following article.

What is DEX (Decentralized Exchange)
DEX (Decentralized Exchange) is a decentralized trading platform where all transactions occur automatically and directly between users without any intermediary.
A Decentralized Exchange, or DEX, is a decentralized cryptocurrency trading platform. DEXes emerged after CEXes and are considered a development from the traditional centralized exchanges (CEX).
In a DEX, due to its decentralized nature, there is no involvement, management, or supervision by any third party. This means that all transactions, including the buying and selling of assets on a DEX, are based on smart contracts and are fully automated.
Users have the autonomy to hold and manage their private keys when trading on a DEX. This mode of operation provides a sense of true ownership of assets and user data. That is, there is no third party monitoring what belongs to them.
What is CEX (Centralized Exchange)
A Centralized Exchange, or CEX, is a centralized platform for trading cryptocurrencies. On a CEX, users can connect and trade the digital assets they desire. Unlike a DEX, a CEX is monitored and managed by a third party, which is the owner of the exchange. This party is responsible for storing and managing assets, developing the platform, and collecting transaction fees.
Transactions on a Centralized Exchange (CEX) are conducted through an order book mechanism. Users can access information about cryptocurrency prices based on the buy or sell orders listed in the order book.
CEXes were established before Decentralized Exchanges (DEXes) and are considered the foundational platform for the development of DEXes later on. The trading volume on CEXes is generally higher because they are more favored by cryptocurrency investors. Common features of centralized crypto exchanges include user-friendly interfaces, a variety of trading functions, and lower fees.
Some of the most well-known CEXes include Binance, KuCoin, Kraken, Coinbase, Bybit, and Huobi Global.
Comparison of CEX and DEX – Advantages and Disadvantages of CEX and DEX
Advantages
CEX
- High Liquidity: One of the advantages of CEX that makes it a preferred choice for investors is its liquidity. With a huge trading volume, buying and selling crypto assets on CEXes is extremely smooth and fast.
- Currency Conversion Features: Major CEXes often allow users to convert between fiat currency and cryptocurrencies. This feature helps new users easily buy coins with their credit cards, for example, buying ETH with USD or VND.
- Ease of Use: CEXes are often chosen by cryptocurrency beginners because they are easy to use. Most CEXes are designed to be intuitive, support multiple languages, and optimize operations on your device.
- Diverse Features: The variety of trading features is the greatest advantage of CEXes. Not only providing real-time coin prices or listing many coins/tokens for users, CEXes also offer many features that make it easy for users to earn money, such as Spot, Margin, Futures, Staking, Lending, NFTs, Betting, etc.
DEX
- High Security: The security level when trading on a DEX is rated higher than on a CEX because of its decentralized nature. DEXes are not monitored, transactions are automated with smart contracts, so users can take control of their personal assets.
- Privacy: DEXes do not require identity verification, thus reducing the risk of information leakage.
- Transparency and Low Fees: DEXes usually support a large number of coin pairs, which helps reduce transaction fees. The exchange is not managed by a third party, direct transactions make information more transparent.
- Support for DeFi and NFTs: NFT and DeFi are both promising investment trends in the world of cryptocurrencies and blockchain. DEXes supporting NFT and DeFi offer extremely attractive money-making opportunities for their users, such as the Lending feature (cryptocurrency borrowing and lending) to earn interest periodically.
Disadvantages
DEX
- Limited Trading Features: DEXes offer relatively few trading features for users. Popular features such as Futures contracts and Margin trading are often not supported on DEXes.
- Low Liquidity: DEXes typically have low liquidity, which means that transactions on these platforms tend to be slower. This is due to challenges related to the scalability of blockchain systems.
CEX
- Security Risks: CEXes are a preferred choice because transactions on CEXes are easy, and many types of transactions are supported. However, since CEX wallets operate under the direct supervision of a third party, this third party has full control over the user’s assets on the CEX. The security of assets becomes a challenge if this third party is not trustworthy.
- Vulnerability to Attacks: Many attacks have occurred on CEXes, which are almost non-existent on DEXes. Since CEXes manage investors’ assets, they often become targets for hackers.
- Strict KYC Regulations KYC (Know Your Customer) is one of the strict and mandatory regulations at Centralized Exchanges (CEX). Therefore, it is not suitable for those who wish to trade privately and individually. To trade on a CEX, users must go through the KYC identity verification process, which can be quite complex.
conclusion
both Centralized Exchanges (CEX) and Decentralized Exchanges (DEX) have distinct roles in the cryptocurrency ecosystem. CEXes offer high liquidity, user-friendly interfaces, and a wide range of trading options but suffer from security vulnerabilities and strict regulatory requirements like KYC. On the other hand, DEXes provide a higher level of security and privacy, promoting transparency and user control over assets, but they struggle with lower liquidity and fewer trading features.
Ultimately, the choice between using a CEX or a DEX should be based on the individual’s trading needs, risk tolerance, and preferences for privacy and control. Investors are encouraged to carefully evaluate each platform’s features and to continuously update their security practices to safeguard their investments.
