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
I think you, yourself can figure out which ICO is reliable out of many scams in the market. You just need experience to look at the website, whitepaper, materials that they use, their team and developers, as well as their telegram groups. These are the fundamental things you need to observe when checking if an ICO is legit.
