I agree, at least we need to burn downvoted rewards instead of returning them to the reward pool. Also, witness rewards are too high (top witnesses making 2k/month, even while the price of running servers (primary, backup, seed node) is less than 500$/month).

Also, DAO will get over 83M HIVE in the next few years. If funds are converted in 10 years, it's still almost 23k HIVE/day. We could burn almost 1/3 of the supply!
