There are a lot of projects that need an KYC of course it is a good idea also to protect their project so that they will know who's dealing with them.But there are some projects that starting from beginning they don't have an KYC required but when it come to the time that they need to distribute the stakes of bounty hunters they are asking for KYC,if the bounty hunter can not comply this where is their stake goes?if the project require an KYC they must announce it from the beginning not in distribution time.
We all know that some of those projects that needs KYC are gonna be scam but also some are not. Nothing changes the only thing about that is the addition of KYC.
For ICO they can apply KYC but for bounty hunters i think there's no need to do that because bounty hunters not buying there tokens/coins only the ICO participants.
