Interesting. And insane.
When you say it pays to be first, do you mean it pays the seller for the first round sales?
in the current market, as especially pertains to Casablanca, due to the 'sky is the limit bidding', you have to be the first person to consign a particular size to get that price. Once the top bidder gets his item, which is almost certainly the first time, due to his wealth, the price goes way down, because the underbidder only has to bid against the third bidder, whose interest in generally, at a lower price point, if you look at & track the prices.
