this appears to be connected to the Greek stockmarket collapse and capital controls that are most likely being bypassed using Crypto
Or maybe it's not, and BTC-E is pulling shenanigans again

I can't see any incredible surge happening on BTCE today. The highest its gone in 24 hours is 283 and the lowest is 277. Other exchanges have had higher prices than that during the course of the day. I wouldn't describe anything as a surge unless it had gone up $20 at a minimum. About a $20 to $30 price increase might be a surge, but not an incredible surge.
