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's very hard to find a promising bounty, because if we read the white paper, it's all very promising, but at the end of the team's campaign is blurred, and does not provide clear information. luck factor is needed here.
