There are plenty of good bounty campaigns in this forum and the first thing that you need to be mindful
of is if the actual product or initial coin oddering is as good as they are claiming it to be.  You should also check the project team behind if they are legit and if they are very passionate bout making sure that the campaign is running as it should be.  one criteria recommended to me was that there should be about 20-40% budget allocation for both signature and bounty campaigns as this would mean that they are very certain that they are willing to pay that much of their budget to pay off those who are taking part in the campaign for advertising purposes, to make sure it's a success.  You just have to be mindful that you be very thourough with the rules and be compliant with it too.
In my case ebit campaign was recommended to me and I've seen it's initial offering.  It is now past the pre sale and so it moving to the actual sale at roughly 0.06$/ebit.  I am sure the project team behind this is amazing and so is their coin offering, so take a look at the link below and see for yourself!
