Last week the Ginko "bank" collapsed due to insolvency: as account holders demanded their money, the bank would have been forced to sell off assets at a loss, forcing it into bankruptcy.
The bank had lowered daily withdrawal limits to avert this scenario, but those measures couldn't prevent Second Life from catching an economic virus that is so common for highly instable economies.
The rush on the bank's deposits was allegedly caused by a gambling ban, which supposedly prompted users to take their money outside the game. Others claim that it was merely an old-fashioned banking collapse due to incompetence or criminal behavior (pyramid scheme, anyone?).
