Will you send your docs in KYC case?
Do you think that it really helps to find illegal activities?
I would avoid KYC as much as possible because a)it's a hassle to go through and b)you don't know where that information is going to go to.
I actually see a lot of exchanges that are asking for more KYC than what is probably necessary, some exchanges have even asked for sources of funds information in addition to just verifying someone's identity, and even income details. We've also seen exchanges have no proof of suspecting any wrongdoing but asking for KYC anyways, potentially to delay withdrawals.
Think about it, who would be held responsible if your information was abused? And would you ever know who did it if you gave KYC information across a variety of platforms?
Unfortunately though if you are trading any sort of significant volume these days, exchanges are bound to ask you for your personal info. There is pretty much no way around that.
