You don’t have to but it is important you share the information for the sake of withdrawing your winnings. As part of the KYC procedure, you need to provide information such as your personal information and street address. Without completing the KYC procedure, you won’t be able to withdraw your winnings. Without providing your bank account number or eWallet details, you won’t be able to get paid. You can, however, choose to use cryptocurrencies that don’t require much sensitive information.
