50 points (probably based on my
current rep - but cannot set less)
What size of bounty would you want to give below that? Anyone correctly answering your question should get at least 25 points anyway (upvote + accept). Also, allowing smaller bounties would litter the featured tab IMO.
No option to set an expiry date
The bounty expires when you award it to an answer, or at the end of the week. That doesn't get you to the top of of featured tab earlier, though. If you want to extend it you can always add another one. Again, allowing longer bounties would:
- Make anyone answering wait to recieve the bounty if the investor chooses to.
- Litter the featured tab.
