The whole idea of making such forum post in Bitcointalk is hilarious. How many forum members are millionaires, who are willing to buy an online casino for 1.5 million dollars?

There is something about this offer which screams scam, but I don't know what is it. What's the point of selling a profitable business?
The seller wants to buy a house. OK, but the casino is profitable enough so that the seller could buy a big and expensive house.
411K USD EBITDA per year isn't that bad. Just run the casino at the same profit levels for 5 years and you will have 2 million dollars.
The sellers wants to build a family business. OK, but the seller could use the profits and invest in his new family business.
The seller doesn't want to run this business by himself. I get it, but can't get outsource the tasks and hire some people to run the business for him? 411K USD is a big enough profit, so that the business owner could afford a team of good programmers, marketers and customer support.
