Too small a drop for that.

In the last 2 months I count at least 6 drops like this one or larger.

But the market feels quite differet from a year ago, don't you think?  While the volume is still quite high, perhaps it is almost entirely a few robots trading fractions of BTC over and over again.  So, when a real trader moves, the price jumps by 5-10 dollars and gets stuck there, instead of bouncing back...
