if you want to place bets on sports then I strongly advice you to join asianconnect88 , they take bitcoin and exchange it to EUR and there is no KYC for users who want only to use bitcoin
they have been around for over 10 years , and been using for like 3 months now
you need to contact their live support everytime you want to make a deposit or withdrawal , deposits are credit after 3 confirmations and withdrawals are instant after you contact them
Does sportsmarket or AsianConnect require KYC?
sportmarket yes it requires KYC , Asianconnect no I have been using them for couple of months now and did many deposits and withdrawals
they told me that for bitcoin customers there is no KYC unless you want to become an affiliate
so at the moment no , but IMO you should always be ready for KYC cause any moment the site policy may change
