I understand what you want to say, but that's exactly the point of my proposal, you will appreciate the post of someone with a 100% vote, nevertheless, you can still restrict the post from getting more than 100$ since the post is not worth all of that basically.
In the end, if I'd post "merry christmas" and I'd get 400$ I would feel slightly abusive since I did nothing but wish merry christmas like everyone should. So if I get 50$ but I see all my friends gave 100% to appreciate it but, restricted it a max value of 50$ I'd be way happier.
