Centralized exchanges and decentralized exchanges are the two main types of trading platforms in cryptocurrency trading. Below are their key information:

Centralized Exchanges

- Features: The trading platform is operated and managed by a centralized entity, and users need to deposit cryptocurrencies into the exchange's wallet. The exchange facilitates trades. Advantages include fast trading speed, good user experience, and strong liquidity.

- Representative platforms: Binance, Huobi, etc.

- Risks: There is a risk of single point of failure. If the exchange suffers a hacking attack, mismanagement, or other issues, the security of users' funds may be threatened. Additionally, users have only limited control over their assets and need to rely on the exchange's credibility.

Decentralized Exchanges

- Features: Based on blockchain technology, transactions occur directly between users without the need for a centralized intermediary. Users complete transactions through smart contracts, and assets are stored in the users' own wallets, providing higher security and privacy, as well as transaction transparency, aligning with the decentralized concept of blockchain.

- Representative platforms: Uniswap, PancakeSwap, etc.

- Risks: Transaction speed may be relatively slow, liquidity may not be as strong as centralized exchanges in some cases, user experience may not be as friendly, and there are higher technical requirements for users.

Investors should choose a trading platform that suits their needs, risk tolerance, and technical level. When engaging in cryptocurrency trading, it is also important to comply with relevant laws, regulations, and regulatory requirements.
