I depends because only an idiot would place a sell order for the total amount, as that would drag down the price so much that he would lose a lot of money. The most intelligent way would be to place partial orders depending on market conditions.
It is clear that only an idiot will sell all at once. I'm talking about now if all this sum of bitcoins will be sold in parts. If the a Mt.Gox trustee dropped the market taking out about 35,000 BTC . Then what if you bring out about a million BTC
