That's all folks.
About 30k-35k BTC changed hands in last 6-7 hours on BTC-E, 11k in the last hour. Nice fireworks.
Did anyone watch the actual trades?
I would guess that it started with a buy of ~970 BTC at 21:06. Then there were buys of ~200 BTC each at 21:09 and 21:19, another buy of ~1000 BTC at 21:36, and perhaps one of ~1000 BTC at 21:38 (all times UTC). The rest of the volume may have been just reactions to those buys. So, my guess is that the maybe 2400--3500 BTC total.
But it is not over yet, it seems...
