I admit that I am outdated on the crypto world right now. Can someone give a brief explanation of what DeFi is and what are your top 5 coins/tokens and where do you usually trade it. Thanks! 
Ethereum blockchain developers have come to upgrading the technology and making smart contracts. They thought of (DeFi) banks, loans, and exchanges relying on smart contracts and automatically performed them between two anonymous people using the software. For me, the most promising DeFi project is Uniswap, as they have an excellent development team and an optimistic vision. The others are Kava, Aave, Kyber Network, and Maker. Binance exchange will be the best for them.
