回答: In gambling, the random walk has an absorbing barrier 由 wasguru 于 2005-5-12, 21:06:26:

but due to the finite nature of gambler's resource (time and money), there is a stopping point for any game player, or as you said, an absorbing barrier.

Based on Enlighten's observation, if one stops at an unlucky point, he may lose more instead of winning something.

ANother point i think is relevent is that for the game like coin tossing, any previous lost is sunk cost. If it's gone, it is lost forever.
