I feel this article was perfect. Because it touches upon "yield farming."

This "farming" should lead to a better understanding of DeFi.

Many don't know but farming yields insane returns. For the first time, we are acting as an exchange and we can earn fees, interest, etc. This led to insane returns (sometimes over 600%).

Hence DeFi is catching up. :)

Start with that article and then Uniswap. Then your mind will lead you. :)
