It's definitely not going down $400, and I'm expecting a rise again after a couple of days.
Of course, it will probably take months to get back to ~$600.
Someone care to speculate what price would reach BTC if a random guy (or agency) decides to buy 1 million?
The price would rise to about $610. But not very long after that, the price would also drop (like a price correction).
So, in short terms, a lot would be happening, but in long terms, it would probably keep on the same course.
