So i made an awesome post about how steem was not destined for a big correction correction any time in the near future, then I went and checked Bittrex, and saw that it lost more than 10 percent while i was writing the post.
If you're scratching your head as to what caused this, its that one guy. He was holding like 60K steem, and from the distribution charts, it looks like he sold off at least 30K of it.
Even though steem market cap is fairly high, because so much is locked in steem power (and because you still cant make steemit transfers), one big holder divesting can make a big difference in a market.
