DeFi simply means Decentralized finance. To my best understanding, i think DeFi is a form of platform where money can be saved without any third party and you get interest on your saved funds. I believe DeFi is the solution to bank issues. You no longer have fears of banks crashing or folding up, it is the future as majority of people have started shifting their attention cryptocurrencies. We tend to trust blockchain wallet than other financial institutions such as banks.
Another interesting fact i have come to discover is the strict regulations of online wallets and also its security.
DeFi also give room for users to showcase their talents by organizing contests which also has an opportunity to earn more funds and also improve on their respective talents. The explosive nature of cryptocurrencies makes it more fun rather than the boring nature of banks and other financial institutions
