More keys will make it more complicated and it is already quite complicated.
I am not in favor of instant PD.
I am in favor of PD taxes. I prefer that we use that fund the mitigate inflation the way @smooth is handling now, I think that is working.
I am in favor of 4 week PD.
What Smooth is doing can be done at the same time as this, it is a brilliant idea that's made Hive temporarily deflationary. This idea, the "tax" or "fee" or reclaim bucks whatever you want to label it, would be rewarding long term holders at the expense of short term hodlers.
I am supportive of that. Let's make it happen!
