Whether decentralized finance will completely replace traditional banking remains a subject of intense debate among economists, technologists, and financial regulators. While DeFi offers unprecedented transparency, 24/7 global access, programmatic automation, and elimination of middlemen, it faces significant hurdles before achieving mainstream ubiquity. Traditional banks retain massive advantages in legal recourse, consumer protection, insured deposits, credit creation, and institutional trust, suggesting that the future will likely feature a hybrid financial system where traditional institutions integrate blockchain efficiencies rather than facing total extinction.
