To further illustrate why the longer you hold $DBOND the more profitable it is, let's take an initial $1000 investment into consideration. In this example, say this $1000 is used to buy $DIBS when $DIBS TWAP is 0.95 and then swapped for $DBOND.
If these $DBOND are redeemed when:
-$DIBS TWAP is 1.5, your investment would now be worth $1421.
-$DIBS TWAP is 2, your investment would now be worth $1789.
-$DIBS TWAP is 3, your investment would now be worth $2526.
-$DIBS TWAP is 5, your investment would now be worth $4000.
