I like this idea.
I don't think burning tokens is the best solution. I'd rather see the purchased Hive used to power up an account that upvotes quality posts. PeakD curation upvotes could receive a boost to incentivize more people to produce high-quality content that is actually worth the read. This boost would also enable widening the net and catching more deserving posts that otherwise would receive few or no rewards.
Better author rewards bring better authors and better content. If you reward pennies, you get content worth pennies in return.
