How does the bounty system work?
I want to award +50 for the user who answered my question.
Do I need to start a bounty and after 24 hours offer it?
Or can I just offer +50 instantly?
(I had not start a bounty on the question)
This is because if you start a bounty, there is a chance you will get a better answer. Then you can give the bounty to that answer instead. Of course, if that doesn't happen, just give the bounty to the answer you had in mind.
This is actually a good thing. Wouldn't you rather have a better answer than the answer you have right now?
