Physical casinos are giving way to online casinos. I think that might be why this casino closed down. There's nothing in our age that hasn't been transformed online. Everything that doesn't go online is lost to time. I can't remember the last time I went to a physical casino. I used to go to physical shops to bet on football matches. But now I find them noisy and unpleasant. I think a casino can never make a loss. But it can choose to keep up with the times.
You are right
Although the casino business is a very profitable business, many factors can cause it to go bankrupt. But, in the case of Trump's casino, I think there is more to it than just being bankrupt. When businesses go bankrupt, they do not demolish their buildings and destroy properties, rather they sell off properties to raise money to settle their creditors while the balance left goes to the owners of the business. If Trump's Casino was going through financial and other management issues, demolishing the casino instead of selling it off to other casino owners or other people inorder to make money from it sends a different message entirely. Demolishing the casino is not a wise decision except the casino went against the government's authorities or it was cited in a wrong location.
