I do not like casinos and do not encourage people to invest them but are the two weeks without giving a way to communicate with support team is good? in common cases the site mostly shut down a month or two and then the door is left to connect with support team for 6 months.
But overall, they are still good because they give warning to their users that they will refund their money rather than becomes an exit scam.
I saw few gambling sites that have officially closed and don't have a problem. IIRC, YOLOdice is one of them.
I also read that they have a 1mBTC minimum withdrawal, Therefore, many may not succeed in withdrawing those amounts.
I think they shouldn't do that since it's already stated here.
All funds are safe, and there are no reasons to worry - We will pay every last satoshi in credits.
