I enjoy the swings. it makes things exciting. 
The swings will come and go and past some point they get boring too
. I just buy a little each time it drops. I know what you mean. I actually held off on the last drop and now regret it. Even though it only bounced back a little over $100 I still should've bought some when it dipped below $300. It's getting to the point where I think 'ahh it'll dip down again no rush' even though in the back of my mind i know that's not the smartest way to think.
