It's fairly fun though. I always give myself a max of $20,which I don't always use. Actually only come out slightly down all up I reckon too. It adds excitement to a game I'd otherwise be neutral for. I like to think part or all of the 20 is entertainment,with a chance of some bonus cash at the end. It's also kind of a waste of money for me to bet on a nix game for that reason too.
This whole thing sucks if you have some sort of gambling addiction though...you'd kinda have to keep away from the forum,or at least the thread.
