Why convergent curve?

I m still confused why this is implemented although it helps little bit to stop reward pool abuse. Self comments upvoting stopped but its unable to stop self post voting because it starts circle voting and vote trading. The curve only stop a small user with less stack but a whale can get other alternative to bypass the curve and this is happening. Only small user are getting punished. lots of authors lost engagement on their post because small user stopped commenting because of this.

Why Decentralised Developers fund share in the Reward pool?

If we have 80 M hive sitting on the DAO then why a certain percentage going from the reward pool to DAO. This will only increase the chances to abuse the reward pool.

What if we implement a system like defi?

We have saving account in Hive wallet which is totally useless till now. If there is some reward to park your stack in the savings then it will be amazing.
