I buy it when i think price is low, but currently i don't think it's time to buy. I would wait if price will go back to 350$ and the buy it. But price at bitcoin is like ups and down, you never know what is behind the corner. 
Yeah the current price is too much. I really think it will go back very hard in a few days. Then offcourse I will buy back much lower. To me 2 scenario's are going to happen
1 We see the 500 usd value
2 We go back somewhere in the mid 300
The potential loss of 150 dollar is just to much of a risk, so I am not buying now.
