Maybe if you have a super low cap, high fees, and they automatically close your position at a pretty conservative point. But that’d hardly be worth any broker’s time with that risk/reward, unless they are hosing the borrower with insane fees. Though if that’s the case, putting up collateral would be cheaper (even if you have to borrow it from somewhere).
It was pretty useful as a kid for feeding my Gameboy and Game Gear with batteries I rescued from the junk drawers of friends and family. If they were low, I knew I had to save more often to avoid losing progress if they went dead while I was playing.
