Let's start with KYC, this ICO project developer's will launch a project and state that they want to remain unknown whiles they forced KYC on both the investors and bounty hunters.
I think if you dig deeper on a project and doesn't see who the people behind, then I will stay out of it.
The big question should KYC be mandatory for everyone...
Will the anonymous goals be achieved with KYC?
KYC is not mandatory. However, there are countries that restricts their people to invest on ICO, so to prevent any problem in the project side, they need to enforce KYC as well. Part and parcels on involving yourself in crypto sphere.
