No, there are no additional fees associated with sports betting. All winnings that you receive from your bets go directly to you without any fees. However, it is important to read the individual terms and conditions when signing up for a sports club, as some of them may include hidden fees or commissions that may reduce your overall winnings. Also, many sportsbooks have limits on how much you can bet on a single bet. Be sure to read all the rules and regulations before placing your bets.
