I disagree. BetBTC shut their business due to constant losses which is pretty obvious which is why I doubt any investor would think about investing a huge amount like 10 BTC in a failed business in my opinion.
I'm not really sure if they had loss or not although that's pretty obvious as you said but that doesn’t mean that someone else will have loss from the business. 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.
