The altruist would play. By saying this you fundamentally misunderstand Bitcoin. The altruist that buys (and takes on the risk, joins the movement) is allowing somebody else to withdraw. Likely in a situation better than when they entered, (or at least in accordance with their desire to trade since they are doing this voluntarily). By doing this, we lift everybody up slowly out of debt, and provide a protocol for liberated transfer of wealth for trade and banking. Cashing out early is fine, but there is every chance that it will always be 'early'.
