The price dropped ~50 dollars on June 13, when the previous auction was announced; and immediately recovered when it became known that a single bidder had bought all the coins. Most people concluded from that fact that the closing price was above market. Tim Draper's statements further reassured them that the coins would not be dumped on the open market.
I did not see any significant drop this time. Perhaps the market now assumes that such auctions will have no net effect, and ignores them.
On the other hand, there is no guarantee that all the coins will again be scooped by a single bidder. So far, Tim Draper got a huge paper loss on that purchase, and it seems that he will only enter a syndicate this time (meaning that he intends to bid for less than one lot). Some of these 50'000 coins may be bought, well below-market, by short-term traders who will promptly dump them for quick profit. If the coins go to several bidders, the mere suspicion that some may be dumpers may be enough to trigger a drop.
so the next 144 hours are critical to bitcoin... !!!!
How long after the last auction did Draper actually receive his coins? I would guess it took a few days (if not a week or more).
