I would love to be wrong about it but I'm pretty sure that people competing into the depths of the reverse auction is the only thing that makes curation spread across a wide array of posts more efficient than everyone just piling onto whatever is already hot/trending, and for most people it is also the largest obstacle to optimizing any form of voting automation.
Currently if you see a new post voted into $100+ then there's no curation to be done - go look for smaller people, which is perfect conceptually even if there's a flaw in the execution. After this change however, it sounds very likely that it will be optimal to dogpile into anything that already has traction, knowing it might gain more the next day, which is literally the exact opposite of what the original curation system was made to do.
