At that point, I am back at the step where we have MATIC tokens in my wallet, ready to be deposited on Mai Finance as a collateral. If I do that, I can borrow MAI, swap a portion of it into USDC, create a LP pair and re-deposit it into the farm. By doing this conversion, I "secure" 100% of my rewards by swapping them into a more stable crypto (here MATIC) and I re-inject 50% of my reward into the farming pool (or actually, in this example, 46% because of the 4% deposit fee).
