I sold all coins that cost me more than $680.
I lost 5 - 10% on those particular coins but it made me soooo much more comfortable than I was because the price has been especially volatile the last 6 weeks.
Now my average price per coin down to ~410. I still buy every day and am still adding coins. The fact is I got carried away with the increasing price last month and bought about 5X more that month than I usually do. Consequently, I was going crazy watching the price.
Reducing your exposure a bit can help bring things into proper focus and allow you to see the big picture.
ps I do last in-first out accounting.
