You seem to have misread my post. I didn't say that no one would bid above market price, I stated that they would additionally buy up all the coins on the market below their buying price.
Well you wouldn't want to do it before the bids are in. However, there was a gap between when bids are placed and when the winner is announced, that would be a good time.
edit: Of course, any time after the bids were completed would be a good time. After the auction ends would be just as good for you.
