Neither post rewards nor curation rewards are guaranteed on Hive

Curation rewards are guaranteed, if one curates well, isn't it ? If they cannot, then better they delegate and earn the reward. My point is that, this should not be barrier to bring in some new whales. And I think, being spontaneous in posting is the best way to go, at least that's what I do, no expectation of rewards. Writing big posts often is rewarded more, but then spending time for big posts is equally challenging. So when I get time, write long posts, or post whatever I like.
