Unless Zeev has an inherited stash of money he's burning through, there's also the Darwinian effect which means that the longer one survives in this game, the better one gets at playing it. Zeev has been trading for quite a while, as I understand it. It's like the difference between getting surgery done on you by a kid fresh off his residency and an old coot who's done the same surgery a thousand times. To a person, everyone wants the old coot doing the surgery. Let the kid learn his craft on someone else.
Not meaning to imply that Zeev is a old coot, mind you. <g>
