I heard that some bounties fail to pay participants at the end of work. Considering this scenario, how can one know which bounty is good to participate in?
There are a lot of factors on how to know a good bounty.
1. Responsible Bounty Manager, I think that is a very important factor.
2. Good project, if the good manager is good bad the project who are promoted by the bounty team is worse, then it was a failure.
3. At least pick a bounty that offers the weekly distribution of rewards.
4. The project is already in the market.
