The hidden advantage of a draw like this is what I call the "Big Carrot" scenario. Every big casino must have a "Big Carrot" to draw people to their establishment. This is why you would frequently see fancy motor vehicle draws being done in Brick n Mortar casinos. You walk past the casino and these cars are parked at the entrance, because people walking past will see that there are nice prizes on offer and they will be drawn into the establishment.

Just look at all the free advertisement that Freebitco.in received on this forum when they launched this Lambo draw. I frequently visit this thread and other Freebitco.in threads, because I love this site and I saw a increase in "newbie" activity, since the launch of this draw.

Freebitco.in might break even or they might even lose money on this Lambo draw, but they can write that off as advertising cost, because they would get new users and also inactive users coming back to the site.
