bLEO's yield is paid out in CUB, so they are intrinsically linked. If the price of CUB goes up, you're still farming the exact same amount of CUB in the bLEO/BNB farm, but that CUB is worth more in USD.
Given a high enough yield in this farm this will force users to buy bLEO out of the shear need to compete in that pool and farm more CUB tokens.
