Centralized and decentralized exchanges each have their own characteristics. Centralized exchanges offer a better user experience and strong liquidity, but their security relies on the platform itself, and users have weak control over their assets. Decentralized exchanges allow users to have full control over their assets, with unique security guarantees, but the user experience and liquidity are relatively inferior. Cryptocurrency traders need to make choices based on their own risk preferences, weighing convenience against autonomy to make precise decisions.
