>You get rewards for literally just sitting on the fUSD.
no, you won't. you need to lock either sFTM or wFTM to affect your c-ratio and earn rewards, minting fUSD costs you a fee, and oyu'll need to clear the debt later, so you enter into the swinging situation and will need ot sell some wFTM at a higher price to make up the difference and clear teh debt.
sitting on fUSD does nothing, unless you swap some wFTM for fUSD and aren't minting it, but still, you can't lock that as collateral.
