If you don't need the money, you can maximize your return here by setting your posts to 'powerup 100%' and voting your stake.
You can follow a trail on hive.vote, or if you have the time just vote ten 100% votes a day.
Doing this will give an additional 9% return over the ~3% return on holding hp.
You will find the 'powerup 100%' option in the advanced tab of the front end that you use.
