I'm not sure how big you are talking about so make sure to check the KYC rules in case you aren't willing to do KYC
the best option for casino high rollers these days IMO is dapps on tron , instant deposits and withdrawals with no KYC
Wink used to offer live blackjack but they removed it while still offering other live games , maybe other dapps have live blackjack in case you want anonymous live betting
If you're concerned with KYC policies, keep in mind that Sportsbet reserves the right to ask for KYC (https://sportsbet.io/about/terms-and-conditions). Good luck!
