In addition, I have a couple of questions that can also be added here.

Is it realistic that Michael could have sold his casinos for so much cash that he was able to give the other mob bosses individually tens of millions for their shares? And how much money would he and his partners have made from his hotels and casinos before he sold them?

I believe the Chicago Outfit only received a couple of millions from their Las Vegas casinos each year, but maybe I'm misinformed..
