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.
Nowadays it is rather difficult to determine which bounty is really good. When we see technically we see good prospects and it turns out that token values are not comparable to our analysis. My strategy is only to take part in the bounty as much, and hope that at least 10 percent of the value is enough for me.
