Private casino vs Public
I live close to an Indian Casino in California, so all my play is there. My only experience with on line betting is with horse racing. I play the big races on the weekends off my computer. One thing I notice is that even when I win $$$, I very seldom take it out of the site. I leave it in, so that I can play more races. I think this is the way, with most people. Therefore, you eventually lose it. If I win a large bet, I will take $ but usually it stays.
