Actually i'm always experience participating bounties and till the end of the bounty are they gonna using a KYC.
So it will can going too long to distribute the bounty rewards because of the KYC required.
I only accept KYC when the amount of money I earn from the bounty is over $ 1000, which is a pretty big amount for me, so I accepted to give my information to someone. However, for those who earn less, that is a mistake, many bounty hunters will not participate with KYC conditions.
