Examining the 360k dump on the Kraken chart.  

220k dumped at 2016-12-26 13:05:00 @ median price 0.0003435 = 75.57 BTC

140k dumped in chunks starting around 2016-12-27 10:00:00 @ 0.00032 = 44.8 BTC

So he dumped his 360k for 120.37 BTC = average price 0.000334

I suspect he made about a 55k ICN profit if he was able to buy back in around 0.00029

Entire price drop was due to this one trader, there's no other significant volume spikes on the chart besides him selling/buying 360k (50% of daily volume from one guy)

Conclusion: ICN holders still holding strong.  RIP to the noobs who panic sold into this whale's buy orders and increased his ICN stack
