Sorry to bump this retardo thread, but I have the answer to the question.

The problem with this question is that it is a divergent series. This is why people are confused and arguing about it. Given an integer N, you will at one point be up N units and at one point be down N units with probability 1. This is because no matter how well you've done so far, the probability that you will never go on a streak that will win or lose you that much is precisely 0.

Because of this, it is impossible to say anything about what will happen over an infinite amount of time. It is simply a question of the way you choose to group the terms when you sum them.
