Many a times it is seen that gamblers post a lot of complaints but can't provide proper proof, thereby ruining the casino's reputation for no reason. Everything I read in this thread. OP has not been able to prove ownership of his account. And he managed an account with such a large fund, without properly storing the account information! If someone owns an account he will at least have email access if he fails to do so in other ways. So I think the original owner can be verified with the main email address of that account. I will wait to see if this complaint is resolved.
Duckdice doesn't have solid clear reputation in the past though but there consistency to operate there casino until now is what makes them solid.
Reading the OP case many times including his rellies. He is claiming that his account is already KYCed even though he didn't complete this before which is the reason why his new KYC to prove the ownership is being rejected by Duckdice. Its very hard to judge on this case because there is no evidence for both side for there claims. You can check his statement on this link
https://bitcointalk.org/index.php?topic=5430960.msg61499918#msg61499918 well before there was like 3 red flags active on duckdice.io profile but it seems they have managed somehow to remove them. past of duckdice was worst yeah
No doubt Duckdice was not and never a popular casino on this forum, as i personally have never really heard about them until the complaints from their users began to surface here, and i believe that before now, they have managed to build a good reputation for themselves, which is what i believed helped them scale through and and continued to remain in business all this years.
But the current happening or should I call it developments does not make me surprise though, majority of casinos(business actually) all have their expiry date, it takes grace to continue to stay in business for so many years, and if that grace is gone, things like this will always arise and this entails nothing but doom, it is rather unfortunate that when going down, some this casinos always drag customer funds with them.
They still have tags on their profiles and those tags are given by reputed members of this forum. They were able to remove some more tags so they showed hope of coming back in a positive way. But now these allegations against this casino are coming up which is forcing DT members to look into the operations of this casino again. Since their past is not so clear, gamblers should be a little more careful with them.
