I have seen a lot threads here about how to choose good bounties. It shows the challenges many of us here are going through in choosing a good bounty. If you really want to maximize your chances of participating in bounties of successful ICOs, i will recommend Bountyhive for you. The success rate of their bounties is very high. Their social media campaign is less stressful because of the absence of weekly reports. They have a limit as to the number of participants in each campaign thereby enabling you to earn a higher income. Although there are certain drawbacks in their processes such as your inability to see your weekly earnings on their spreadsheet, in general their services are really good and i will recommend for everyone
Bountyhive in my opinion isn't a very good choice, their bounties success rate is poor and most of their bounties become useless I can name a lot of them lying dead in my wallet. I would recommend bounty0x instead because they are trying but in all bounties on the Bitcointalk have been more than 50% successful
