I like .25....otherwise, since it's a game, we'd be forced to focus on .10 - .15 stocks as they would give the highest chance of winning the game. Risk is be thrown out the window since there's only 1 winner. Realistically the only way to win is going to be gambling with a bunch of .10 stocks which kills the original spirit of the contest IMO.
