I usually check the following factors to determine whether a particular bounty is worth participating in or not.
- Development team background
- Campaign manager
- Social media interactions by the development team
- Whitepaper analysis
- Website
- Number of participants and bounty fund
I research these factors thoroughly before joining any bounty on this forum which is the primary reason I have not been scammed till now. Do your research carefully people.
This is what I was going to say. And you even added a few more points than I would have. These are the things that you should be looking for to check if a project is legit or not. Extensive research is always the best way to find out where a project is headed. Also one more thing, the bounty manager matters just as much as the bounty itself, if the bounty manager cannot be trusted then the bounty cannot be trusted.
