I don't wish to dwell on this matter any longer, but I would appreciate hearing your thoughts. Personally, I feel that this is a highly questionable practice, allowing users to continue gambling while demanding verification for withdrawals, and then conveniently erasing the tickets and evidence. It appears to be nothing short of shady and potentially predatory to me.
Imagine if you hold on and did not play you could have withdrawn your money because Stake cannot hold on to your money for too long because your issue will eventually land in the scam section, this is not an isolated case I have seen this complaint on other casinos too, but some of them able to withdraw their funds even though they can still bet, for a gambler its very tempting to play while you're waiting for your KYC to get verified, but there will always consequence like what happened to you.
So next time if you get in the same situation not necessarily at Stake, control yourself from using the money that you cannot withdraw.
