Maybe Megadice are doing it on purpose ? Going on the probability that if a user won't be able to withdraw / his balance remaining intact on the account the said user might continue to play improving the odds of him losing the balance .
We can reassure you that we had it like this since day 1, even back when satoshislot was a separate site in 2015, i would say. There is no intention to do anything, just that we find it bad to lock user funds so that we wont be able to do anything with them. We may consider such functionality though, so that someone can decide to lock funds for withdrawals if he wish.
Kindly read the whole thread and our answers. We already explained, with logs also, that when this user reached the peak of 19BTC, instead of waiting, he made another 2000+ rounds! And since he run out of luck, he tries to defame us and trying to negotiate. If he stop gambling, would we negotiate paying him 19 BTC? Ofcourse not.
Furthermore, newalias started trying to defame megadice from the very beggining of his winnings (even when he had 6 BTC in wins) without even waiting for the support to respond and refill HW. Our support was really bad, yes,but this does not prove that we are not legit.
