It is indeed subjective into some gambling sites but it would really be great to hear out that there would be no further verification incase you do win up big time.
KYC is highly frowned upon with this market which is no surprise.We do much prefer on staying up anonymous.
Unfortunately, majority of the crypto sites usually force you to submit your KYC when you win big in order to verify your identity and the winners usually succumb to this practice since it's a matter of money at the end of the day.
This isn't necessarily a bad thing for some while some others really hate this kind of stuff. I simply hope more and more crypto casino and sportsbook sites stop forcing KYC onto winners as time passes.
