Posts, comments, and upvotes on the main page cost 1 sat. These will never cost more than 1 sat.
When people upvote your posts and comments, those sats go to you.
The basic algorithm divides upvotes by a power of the time since a story was submitted plus the boost divided by a larger power (relative to upvotes) of the time since a story was submitted. Comments in threads are ranked the same way.
Upvotes (denominated in sats) go the user that posted the story or comment being upvoted. Each user can upvote a story only once.
Boost allows users to boost the ranking of a post upon creation.
If you press the upvote button a second time, a dialog pops up to tip. Optionally you can set this amount as your default tip to avoid the dialog on subsequent tips.
On the settings page accessible from the dropdown menu. If you only want to temporarily vary your default tip, you can press and hold the upvote button to present the tipping dialog.
