probably poor phrasing on my part. didnt mean to imply it was one person. 60k is simply the trading volume net result for the day of the price spike on mtgox. basically at the end of the day there was a larger volume of coins bought for higher value than the going rate, result price goes up. this is in contrast with the avg daily volume which is in the 2-10k range either positive or negative on price. all it means is that people were putting more dollars into the exchange, putting upward pressure on the value.
