How should Defi learn? This is the most common question asked by many beginners of Web3. In my opinion, to learn Defi, the key is to understand what Defi's sources of income are. There are several mainstream sources of revenue for Defi projects: one ⃣ Interest on loans two ⃣ Price arbitrage (including anchor detachment scenarios) three ⃣ Pledge income (there is an opportunity to eat more than one fish) four ⃣ LP pool transaction fee income five ⃣ Arbitrage of fund rates six ⃣ Bribery mechanism (assuming holding a large amount of governance tokens to determine the yield of the treasury) seven ⃣ Cross chain bridge transaction fee In addition, another key point is that, on the basis of understanding the sources of Defi's returns, the most crucial thing is to put them into practice. Practical experience will deepen our understanding of Defi and may also reveal opportunities that bring excess returns. BTC DeFi
