although I like the idea, I do see some drawbacks. Mainly the use of what you have termed another 'currency'. We have steem, we have sbd, we have vest, and now we will have RC.
This opens a question...will smts need SP or RC to run smoothly? SP will give you RC, so its still SP that is needed right?
I was thinking the same thing.
If it's proportional to SP, why not just use a portion of the voting power rewards since that's already built in?
