I use a gambling site (bitsler) from several years and they never asked me any kyc and they provided me telegram support. But while I have win few days ago they asked me to verify kyc and after verification they reduced my bet limit on cricket. So, those site which you are using obviously will do the same if you win any big amount. Also they may decrease your bet limit.
Hate to break it to you, but I did win big amounts(0.5 BTC) from a crypto gambling site sometime back and they
never asked me KYC. I never won consistently anywhere which is why my bet limits were never reduced so far.
It was back then, but every day is a new day for crypto casinos. What is ok yesterday may not be ok today or what is ok today may change tomorrow. The same goes for the implementation of KYC. We really can't compare the rules of yesterday and today. Years or months back, Roobet is ok with no KYC withdrawal even with a large sum of money but due to the changes in regulations and requirements of the authority regarding casinos, Roobet and other casinos have to adapt to the implemented regulations if they wanted to operate smoothly.
Overall, it's still possible to withdraw your winnings from some crypto gambling sites without providing KYC.
True but I think the trend of Casino will be KYC implementation so it would be just a matter of time before those non-KYC Casinos start requiring their player to submit documents for KYC.
