On Stack Overflow, a bounty can be offered for as little as 50 reputation points. As a relatively low-rep user, I'm not all that excited about offering 100+ bounties on other questions as a means of generating interest in questions that I think are meritorious, but what I have very little stake in personally.
Why are we prevented from offering 50-point bounties? Can that be fixed? If not, why not?
From Clever bounty reputation hack:
If you are placing a bounty on a question you answered, your minimum spend is 100
If you are placing a repeat bounty on a question, your minimum spend doubles till it reaches 500
Since you've already answered this question, your minimum spend is 100. However, you could use chat to try to convince another to leave a bounty.
Or, as you've done, leaving a comment is a good option as well to see if someone else is interested in bringing more attention to this question.
As an example, I posted a bounty on How do you calculate schedule compression ratio?. While I had the option to post a 50 rep bounty, I went ahead and posted it for 100.
