12h ago, XST was at 9k. Now it's at 8k. Where's the problem? Someone got out, another one immediately stepped in - good sign for a good coin. Who cares who left / entered - at the end it strengthens the coin (as demonstrated right now by StealthCoin).
I agree, I had been wanting to buy and just happened to log on when it was going down through 7k. I was able to load up, and am quite happy.
The good thing is, beause of the quick recovery there aren't that many lucky owners of 6k-coins left that haven't sold at any point. So this time 10k should be a piece of cake, I'm more worried about the 15kish area.
