HOW are negotiations between BOUNTY MANAGER and ICO?

[Rainbowwww]

Hello everybody!

I'm interested in the issue of managing the company's bounty.
Someone has information on how to ask managers to participate in the conduct and creation of a bounty program? By what criteria do managers choose bounties?

I just recently became interested in participating in the bounty and try to get deeper into all the nuances. Thank you in advance)
