$16 and falling on MtGox as I write this. The 'island of stability' around $19 to $20 didn't last too long. Those 25k stolen BTCs being unloaded today after being laundered over the last couple of days? Dead Cat Bounce has had its run? ($30 -> $10 -> $20 -> sub $10 if that's the case). Interesting times.
Like any economy, it will have its ups and downs; we seem to be experiencing a nice little downtrend. I wouldn't worry too much about it.
