If all that is true and you can pass KYC, I think you will be paid according to the terms of the bonus. I'm not sure if there is a max payout or whatnot, ~
Judging from the provided evidence, it is a true story. The support hasn't asked him to pass the KYC verification yet. The security check up for his pending withdrawal may take a bit long time as it is the weekend. There is no max payout limit rules in the terms of the promo in which OP has participated. And the terms say this:
5. You can keep track of your wagering requirement on the Rewards page. Once you complete the wagering requirement, your remaining funds in the bonus are automatically transferred to your account cash balance.
@OP, You will receive your withdrawal if you haven't violated the promo terms and
general terms and conditions. You may send a PM to
Bitcasino.io Support if the waiting time become very longer. Otherwise, post the link of this thread in Bitcasino.io ANN thread as Little Mouse has suggested above.
