Dear Christian,
Thank you for contacting us.
Please be informed that the bonus wagering requirement is 40x times the amount of the bonus + deposit, however, a deposit itself only has to be rollover once, so if you deposit €100 you only wager that amount to be able to cash out.
However, notice that the funds remaining in your account are from the bonus you received, therefore, if you deposit while having these funds in your account, you will automatically have to complete the wagering requirement of the bonus to be able to cash out. We suggest that for now you keep playing with the bonus money and to wait until your balance goes to zero (€0) before making a new deposit.
Do not hesitate to contact us again if you have any more questions.
Best regards,
