So 1xbit should deal with unresolved issues, if the reputation is not clear then it will not be profitable to spend huge amount of money like this.
Thats true. It will be futile to spend huge money for promotion if the reputation of the site is not good. Because gamblers are wise now to not risk their money on a shady site. Hence they should resolved first the past and current accusations against their site. If they manage to do so then there's a chance to for their casino to look different but I doubt if they even have plan to do that.
