Try to avoid bounty hive as I noticed that recently all users got negative trust for bounty scam so next time just avoid bounties like this and do your own research of the project.
It would be nice to have some fresh rulles for bounties as more and more turn out to be scammy projects.
I think that there is nothing complicated. Since the threads of old bounty projects are stored on this forum and you can easily calculate your own formula for a successful ICO. Based on those or other indicators that have made the project successful.
