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.
