Serious question - does this work? I'd never heard of it before and checked it out, and it seems a confusing mess.
If I understand it, someone opens an issue then assigns a bounty. But clicking through a few, it seems to be a free for all. People asking to be assigned, other people making PRs, yet other people asking for clarification, yet other people asking if it's still open.
It's a cool idea, but I can't think of a worse implementation.
I've issued a few bounties on my repo [0], and it's worked fairly well from my perspective. I'm both the bounty assigner and the maintainer in this case.
Keep in mind that open source is always a bit messy, and a lot of people on all projects (even without bounties) never actually follow through with contributions that they plan to do for a whole host of reasons. The way I've approached it is once someone either has a track record of contributing or makes substantial (visible) process on a PR I assign the bounty to them.
