Alas, the bounty does not bring the income that was brought before. I don't even know if I should be involved.
I think it depends to the projects whether it will succeed or not. Joining bounty is like choosing a good ico project, though mostly iconproject now a days are scams based on what i observed compare in the past few years. Bounty is another way or a marketing strategy. For me choosing a bounty I should check the team and staff behind it and its community.
