"Happy" is a mislabel
"Familiar with its fluctuations while on the greys" is more like it. This drop to par value is a bit more interesting, though. It could be, as someone else said, a person who set market value on a very small sell, or something else. It is the case that no one has seen this low of a drop in several months, imo.
I immediately placed a bid for 300,000 at twice the (highly misleading) value, then changed the order to 100,000 @ .001, with zero result. Very tough to know.
Moral: Try not to divine meaning from greylist fluctuations, and ride with it. Not much else to do.
