How to Trade on Decentralized Exchanges: From Basics to Techniques

With the rapid development of blockchain technology and the booming rise of the cryptocurrency market, decentralized exchanges (DEXs) have become the choice of an increasing number of traders. Compared to traditional exchanges, decentralized exchanges are favored for their decentralization, high security, and superior protection of user privacy. So, how can one trade on a decentralized exchange? This article will provide practical advice and tips to help users navigate this emerging market with ease.

Understanding the principles of decentralized exchanges

A decentralized exchange refers to a trading platform without a centralized management organization. It allows users to trade directly through blockchain technology, enabling them to exchange crypto assets with each other without intermediaries. For example, users can trade via smart contracts, transferring their assets directly to the other party's digital wallet without the involvement of a traditional exchange.

1.1 Differences Between DEX and CEX

Centralized Exchange (CEX)Users are required to register and deposit assets into the exchange, where the exchange is responsible for managing trades and asset security.

Decentralized Exchange (DEX)Users retain their own private keys, directly controlling the security of their assets, and conduct transactions through smart contracts.

1.2 Advantages and Disadvantages of DEX

Advantages：

High securitySince users do not need to deposit assets into the exchange, the risk of funds being attacked by hackers is relatively low.

AnonymityDecentralized exchanges usually do not require users to provide personal information, offering better privacy protection.

High degree of freedomUsers independently decide the assets and prices for transactions.

Disadvantages：

Liquidity issueSome decentralized exchanges have relatively small liquidity pools, which may lead to insufficient liquidity.

Poor user-friendlinessCompared to traditional exchanges, the interface and operation of decentralized exchanges are more challenging for beginners.

Choose a suitable centralized exchange

Before engaging in trading on a decentralized exchange, it is especially important to choose the right exchange. Here are some selection criteria:
