What i know, KYC means Know Your Customer ! Bounty hunters are there to Support ICO Project to spread the word about the project .. BUT as soon as the Project manager mention KYC then many Hunter run away ! Why? Is it because people don't want review their identity for security reason or people are joining campaign with bot software ..
i know that KYC is a confirmation of your current place you are living so that they know if the coin will be given to you.
some bounty hunters dont have the requirements for the KYC thats why sometimes they lose hope on getting their coin .
