I've never participated in a project which asks for KYC information yet. And I do not actually plan to do that, only if such thing will be required everywhere, in that case I simply will have no choice. I am not so afraid of the system, but about protection of my private info. There are not guarantees for 100% safety and I am afraid my private info would be used for wrong/illegal targets.
of course no one will guarantee that your identity will be safe. even though they are trusted agencies though. give identity especially stand photo with yourself and your face is the most risky thing. because someone can be very easy to abuse it. yeah I also never took part in a project that required KYC, I also never verified data on exchanges or wallets
