WTF just happend that ETH dropped nearly 10%? 
Many ICO going to run their main net in upcoming time. So i think they start dumping ETH to convert to fiat for their development purpose. And combine with this bearish market. The right choice if you have to bring the ETH to fiat, because that's where the safest place for now, the possibility of falling worse so it can get a lot more when buying.
but what if this is already the dippest? I really have a hard time making analysis on fiat/crypto market. I am closely eyeing on ETH as I am planning to buy more. I haven't sold and make cut loss on my previous holdings as I felt long term is still very healthy here.
There will be more ETH usage in the smart contract application. So the price will rise a lot again.
