It is obvious to me that with the BTC China bank deposit re-acceptance news, people began to buy BTC at there.
Immediately, someone sold those exact amount just to keep the price stable. What a trade volume!
Being successful, people gave up making short profit. Significant volume down.
I call it price control... but who and why? when does this "project" finish?
The moment it finishes, price would start to move. I don't think it would be downward.
