Changing some strategy would bring profit in the table. And 10 BTC isn’t quite high if you consider the domain name, the reputation it has built and the user they have on their platform. All together it may not be a huge amount.
Possible, but very risky. Many investors would think twice before investing because of the competitive crypto gambling market at present. I can't think of a single crypto gambling site that resurrected successfully after shutting down their business.
I think that it would be better to invest such a big amount in a popular casino's bankroll for long-term profits instead.
