For Newbie How check Which bounty program is good or which one is Scammed and i have heard that many good ICO still not launching there coins
There are so many criteria, one of them is who's handling the bounty campaign, there are bounty manager that protect the reputation of their services and we have seen legit bounty campaign are under highly reputable bounty manager, another one, the project passed all legit test, like whitepaper not copy paste from old or already existing projects, the people behind the projects also counts.
I have been in some notable and reputable bounty managers but almost (not all) are scams. I worked in some bounty like Mb8 managed by Yahoo and Dogdata by Wapinter but it ends up trash. I somehow understand that these results are not because of the bounty manager but the project team.
