I will start with one to begin the discussion. If you are putting huge amounts at stake and want to keep identity private, online gamblign comes as a boon.
But there are instances on where you do really need to pass up KYC for some gambling sites when we are already talking about big amounts. Depositing might not be a problem or would like a breeze but when you are already withdrawing then expect problems would possibly faced on these times. Im sure that most gamblers do knows about this. The thing we do like is anonymity but instances of KYC has a chance for you to comply on some situations.
That's correct, sometimes you do lose your privacy in gambling websites due to kyc. However, it's still an advantage to use them compared to Fiat gambling websites.
There is far more bureaucracy on Fiat gambling websites, and you will probably lose a lot of money on fees to convert your local currency to usd. You will not have that problem using bitcoin
