Hmm, 33 buy wall taken down quickly... Maybe not...
Same thing happened yesterday. ~30BTC plowed through in one shot on a big sale after buy wall installed. Somebody really wants DRK down.
Ya, the same people who are dumping are the same people who are buying after they dump at lower price. It isn't rocket science. If I had a few 1000 DRK I'd do the same thing.
