While some bounty hunters lay more emphasis on the community members of the project. I tend to look at the technical aspect of the Whitepaper, website structure and team because I have seen a lot of projects with large communities failed.
It goes just beyond that, even if a project have large community which is mostly inflated by airdrop participants. They project might still fail.
You need to do some research about the authenticity of the project and then go ahead to do some basic plus and minus (research) to know how much the team allocate for the bounty campaign.
some of this campaign even if they are real, allocate pennies for their campaign and you wouldn't want to work for the long period of time only to receive penny at the end of the period.
