USDT withdrawals and deposits are accepted at most casinos these days and you won't face any issue with such withdrawals or deposits, but when it comes to the sports betting websites or the casinos that have sports betting available then most of those are the ones that require KYC.

However, when you're just starting and not betting with huge amount like 1000's of dollars then you should not worry about KYC that much. I suggest you to check Bitlist.co where you'll find the sports betting sites that doesn't require strict KYC. You may also check out Coinroyale.com as that's a reliable site and it has sports betting available.
