It goes up. It goes down. A month ago it was $193. Then it hit $400. Now it's about $300. Getting out now because it's dropping is most likely shortsighted thinking. I'm sure it will be over $500 a month from now. I bought some at $170 and some at $340. I'm not that concerned.
Well I trade, I'm not all the way out, just trying to increase the amount of ETH I have from what I invested 2 months ago. I started with $1200, sitting at $2400 now. Not bad in 6 weeks.
