Even if the website is not closed right now, it means it will be closed very soon. How many casinos can actually return from "sorry we have been inactive for weeks now" to "we are back and getting great numbers again" all of a sudden?
If they are gone than that means they have been gone for a while already, if they are not gone than it means there is still a chance they will comeback, maybe pay people their money but than nobody will want to play here because of what happened and the casino will be closed anyway, so they have to choice but a result with closed casino in the end no matter what happened right now.
Knowing that (I mean I know this, so the owner must know this anyway) they might not even comeback anymore because they will lose all their profits so why not keep peoples money.
I agree that what has happened can harm their reputation and cause them to lose some of the players and so a part of their profits. But souldn't judge them that fast. Bitdouble has been live for about 2 years. It's not a short time. Happening of these problems is normal, however the maintance is last long time.
if they want to close their website, they can easily run away without any explanation.
