The archivist first saw $DOS as a line in a block and thought nothing of it, which is how most of these begin. It was 7.3 hours old when this page was last touched. 20 buyers had found it in a day, 84.84 ETH had moved through it in that time, which on a chain this loud is neither much nor nothing.
Nothing moves in it any more, and it was $61.8k at its best. A coin does not announce that it has stopped; it simply is not bought again, and then it is a page like this one.
The page stays where it is. Somebody bought this at its highest, and that is part of the record too.
