This is from the Stacker News FAQ, about how the daily rewards work. You might even find a cowboy hat!
Every day, the users who made the best posts and comments from the previous day will receive extra sats as a reward. Stacker News also rewards the users who identified and upvoted the best content on the site each day.
The extra rewards earned for posting great content depends on how popular your content was among trusted users.
The extra rewards for identifying and upvoting content depend on a few factors:
How early you tipped content (earlier is better)
How generously you tipped content (more is better)
How popular that content was on the site (more popular is better)
How trusted you are on Stacker News (higher trust is better)
