It was me.
At this point we're pretty much just following the BTC price moves anyway; doesn't really matter how many are dumped/bought at any given time cuz the market ultimately keeps following BTC.
Edit: I see what you mean, the 2,000,000 sell wall at .000053. Yea that just looks stupid. I'm sure it'll either get eaten or pulled if BTC makes another leg up. (Then again, the wall is for bitcoins, not CNY. So I guess a bitcoin run-up will ultimately result in a wash. Unless BTS rises faster than BTC...)
Bottom line: I wouldn't worry about it. Market does what market does.
