In general - I really like this idea because if gives more incentivize to power up to get those additional curation rewards. I think that in general part of the curation rewards should be paid in liquid form because then you don't have to power down to make use of your earned rewards. Powering down feels kinda like damaging your account while you might need liquid Hive to invest it into a project, send a tip, sell it or just power up to get more liquid rewards. Hive account@reward.app aims to bring this functionality to Hive.

What you have invented is a way to bring back bid bots to Hive. This will cause a race to the bottom for authors who try to outbid each other to entice opportunistic curators looking for maximum ROI.

The logic that powering down feels bad but liquid instead of powered up rewards don't escapes me.

Then, there's the problem of punishing late votes that I've mentioned above.

That "problem" won't go away by redistributing some portion of the author rewards to the curators of a post under rules where the early voter advantage does not apply. One of the stated goals of this project is motivating curators not to eschew voting on high quality posts because they've got votes on them already. I think an incentive to spread out the author rewards wider has done a lot of good on this platform. It's a lot less work to just concentrate votes on the same old high-earning authors. I'm afraid this project will undo some of the good that the EIP brought about.

Of course it happens at the cost of the author's earnings, but - if you provide additional reward for curators, you can expect more upvotes which will make up for the loses. Or not? That's the thing - we'll see :)

Curation is easy to automate.
