The newbie has a point this is part of the reason. What many are forgetting is that the MTGoxBTC/MTGoxUSD price is not an indicator of MTGox's financial health, far from it, but rather an indicator of the chances of a MTGoxBTC holder being paid vs a MTGoxUSD or other MTGoxfiat holder being paid. One of the reasons for the drop last week is sizeable MTGoxBTC holders selling for MTGoxUSD in order to position themselves to sue. Once the deadline for the lawsuit passed many of those that chose not to participate or were too small to participate would buy MTGoxBTC in order to exit via Bitcoinbuilder.
