we realize, many bounty campaigns that appear in bitcointalk. what I want to ask is do you have your favorite site to track bounty Campaign 
so which one is your best ?? what the reason??? not just to track it but know the quality of bounty campaign, and of course always update bitcointalk that we want to follow thanks
My favorite site to track bounty campaigns is cryptocreed ( https://cryptocreed.com/ico-bounty/ ) Here we review bounty campaigns before adding them. You can find only trusted bounty campaigns only. But still, join any bounty campaigns on your own risk. No one can give you guarantee of Legitness of ICO. so which one is your best ?? what the reason??? not just to track it but know the quality of bounty campaign, and of course always update bitcointalk that we want to follow thanksI agree with the legitimacy comment as an ICO is an unrealized dream and when/if funded, things dont always work out so easily
