It hasn't been "trading" in the normal sense of the word. It's essentially dead. If it weren't for KA/GAs monthly manufactured trades, there would be almost zero trading for months at a time. Can't let that happen, can we?
I think what we just saw was someone who knows how dead it is and just said "Screw it, get what I can and forget about it."
Or even if it was a n00b mistake, it was still a real trade. Just not one you're fond of.
No worries, KA/GA will artificially arrange to trade it back up. .0001 is just too humiliating for this "gold mine".
Of course this post is my opinion. Every post by anyone is an opinion. I'm not writing a white paper on scams… in this post, anyway...
