It all depends on what you think the outcome will be with Gox.



If you think Gox is insolvent/will declare bankruptcy you are better off selling, because it may be easier to get the money back in a lawsuit if your balance is in actual money.

However, if you believe Gox will allow withdrawals again and go back to business as usual, you should buy or trade.

If you cant decide, you are best off just holding.
