These weren't borrowed coins. Somebody needed quick cash, probably because they were long something that got crushed.
IOW, 27k XMR moved in a flash from weak to (relatively) strong hands.
Congrats to the lucky bidders who caught that falling knife!
I hope we revisit the 0.0009s one more time, so my stinky-skunk bids get filled.
It is somewhat positive that most of the decline can be attributed to this dumper and another 7k dumper. Few months ago it was just dumping non stop when Bitcoin went up. However, we haven't broke the altcoin-peg / correlation yet.
