I do not think that too many have won with that kind of setup. Majority of the people here have been gambling for a long time but if it's about winning, you'll see how many are happy to share those moments, of course. And it has become a norm when someone wins big, the casino will ask you kyc for that. They also need to comply to their government so whether you like it or not, you have to.
Personally, I won around x50 - x100 plenty of times through small sports accumulator bets and was never asked to submit KYC so far though the amounts weren't huge or anything.
That's nice to hear that you haven't asked to submit kyc when that's a lot of money that you've won against that casino you've played with.
Almost every crypto gambling site will request KYC if the amount is huge these days though only a couple of them give bullshit excuses even after providing KYC.
That's right, it is to be expected when you're gambling and you suddenly won huge amounts these days. Even if there's a promise that there will be no kyc from the beginning, you don't believe that.
Smaller withdrawals could bypass KYC, but it would take a lot longer to fully access your winnings.
They'll notice it if you'll withdraw in many small parts and will still end up being kyced.
