Talking about the bounty it goes with the ICO,s. If your talking about the bounty this goes with the bounty manager and how he manage the campaign,a bounty can be good but the manager can decide to cheat on the bounty campaigners
You really want to look for good projects, with high allocations to the bounty program. If it is a good project with a high market cap potential this is a great start, but a project that also has an large allocation has a much great chance of paying out well for participants.
