How to choose profitable bounty ?What factors we should analyse before pick any bounty

I feel that every bounty program is profitable as long as we are on the right bounty program (pay) because we only have time and mind ,,
factors that must be analyzed are
1. managers (trusted)
2.tim (experienced)
3. product goals of the project (which can make changes in the future)
4.kertas putih
5. roadmap
6. token allocation and token value that we will get (which is in accordance with our performance)
