The only people who will qualify for curation rewards will be those who make the best predictions on the future payout.

This will exclude ocasional users from being curators and may also frustate newcomers that dont get to be curators from using the platform.... steemit would become more like gambling site for a select few

I think steemit needs to be kept simple, I dont think bots will be an issue once steemit has 100.000 users because it is impossible to predict what contents may become viral, however if @ned and @dan think upvote bots are distorting the curation process I think its best to remove the rewards all together.
