I doubt a well known bounty manager will take the deal of "payable upon a successful token sale" ; "willing to take a risk and be apart of something huge" . Instead, you will received a random offers by not popular managers here but who knows someone is adding experience to their portfolios and willing to take the risks.

Well then the details are private between you and the manager so hope you got a good manager that will take the deal. Be careful choosing as the community can't guarantee the credibility of those inexperienced managers.

Goodluck finding a good one.
