DeFi vs CeFi are two distinct approaches to the financial ecosystem. DeFi operates on decentralized blockchain platforms, offering transparency, autonomy, and trustless transactions without intermediaries. CeFi, however, relies on centralized authorities like banks and financial institutions to process transactions. DeFi provides greater privacy and control, whereas CeFi offers customer support and higher liquidity. Both have advantages, with DeFi focusing on decentralization and CeFi offering a more familiar, regulated approach.
