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.
These sites are platforms for conducting bounty campaigns. Of course, both of these things are related. If the goal is not achieved in ICO, there will be no rewards for hunters. I try to independently analyze projects for participation.
