There are many popular sites are available like Bountyhive,Bountylord that gives the ICOs announcement their duration time etc.
I want to know that how you select an ICOs to either participate in it as invester or a bounty campaigner.
Of course I have to be selective I try as much as possible to avoid get scammed. But it needs effort to research and keep on asking my friends if they have idea of which project is good and which project has big chances that it is scam.
