As blockchain technology evolves and cryptocurrency becomes more popular day by day, adoption of decentralized finance (DeFi) is becoming more prominent. While government-controlled fiat currencies and conventional banks still dominate the financial markets, we are witnessing a shift. In the near future, virtual banks and cryptocurrencies may become standard for many transactions. It might be little early to say DeFi might replace traditional finance, but we will see DeFi having a major role in the next financial revolution.
