It does sound like an interesting idea, but I do prefer the liquid hive payment everyday, reason, it's just one less element to worry about... Watching the internal market value, vs hive pice, then remembering to sell...
Perhaps you can offer a choice between receiving the token or the internal coin?
We thought about this. But it can be hard to calculate the weekly delegation report and also requires a lot more coding and automation to manage it this way. With IUC tokens we are also able to give a few extra rewards to the delegators. Please reach out to me (Bala) on discord and we can have a discussion on this.
