How does the bounty system work?
I don't see a bounty button on a question of mine that's older than 48 hours and when I checked the bounty FAQ, all it says is:
If you don't see the bounty button on a question, one or more of the following applies: * The question has been asked in the last 48 hours. Give the community a chance to answer your question normally first. * You already have an outstanding bounty. You can only have one open bounty at any one time. To start a bounty on this question, you must award the previous bounty first. * The question already has a bounty. To start a second bounty on this question, you must wait for the current bounty to be awarded first.
Since none of the 3 points above apply to my question, I am wondering: Are there additional requirements for a bounty button to show up?
