I have one regular practice, and that is to always hand out my kyc documents for verifications immediately after my account creations, this help me to overcome alot of stress along the way since i dont know which casino i have the luck of hitting my first 1000x multiplier that make me the jackpots winner and want to withdraw on $100Ks without problems.
So for sure anyone can do that as long as you have nothing to hide and you trust the casino, making sure you give your documents to only reputable casinos, this will definitely make alot of sense solving all this KYC issue's.
I understand your point mate, but even with KYC completed, it simply doesnt eliminate the fact that they can still ask for additional documents whenever they want, duh not so helpful. Thats just how these platforms operates and it can be pretty annoying at times. But yeah, that 1000x multiplier would be one hell of a story to tell others. Imagine bragging to others saying you turned a small bet into something massive overnight. I hope you actually win one someday, it would be amazing thing to witness....
