Token is a one kind of term who used for rewards that will be distributed. It is bigger form of coins, meaning it could contain x amounts of coins in it associated with that ICO campaign.
I understood what tokens are? Now I have one more doubt what is stakes means some bounty campaigns will pay ten stakes and 20 stakes what it means?
Well for me stakes are like reward that you get for completing their required post or for obeying their rules. At the end of every week the campaign manager check if you completed the tasks or posts then reward you a stake. Giving stakes depends on what rank are you. So the higher your rank the higher the stakes you get.
