We won't know until they actually pay campaign participants who have participated in 3 stages.
but looking at the signature of the bounty campaign, it states that they are even listed on several major exchanges. This may be the case that the bounty participants are very interested in participating in the campaign for quite a long time, even without being sure whether they will be paid or not.

Bounty participants may panic when distribution decisions continue to be delayed. but they should also be aware that they may not get anything from the bounty campaign. not protecting the manager's bounty, but unless the manager is already holding funds but not distributing them, that may be a different case.
