If your Hive funds arent staked then youre subject to inflation which means you lose by holding liquid in the long run.
That's only if everything else stays the same. But development and future investment continue to build, presumably leading to an increasing token price.
Regarding the proposal, I'm not going to vote either proposal. I would like to see a system where the longer you power up the more your vote is worth, and the more inflation rewards you get. Not sure how easy or hard this would be to implement. But it has been received positively when it's been raised in the past.
