DeFi vs CeFi are two different approaches to financial services. DeFi platforms operate on blockchain technology, allowing users to directly interact with smart contracts and decentralized applications (dApps) without intermediaries. In contrast, CeFi platforms rely on centralized authorities to manage transactions and custody of funds. DeFi provides transparency, increased privacy, and lower fees, while CeFi offers convenience, customer support, and regulatory compliance. Users must choose based on their needs for control, security, and reliability.
