You may call him "weak hand", but certainly he had enough to move the market.
I call him Santa Claus.
The threat was (likely intentionally) issued at a time when me and several other large holders were online in the trollbox. I don't know if the other holders sold, but if they did, it was likely in anticipation of a bigger drop (which never materialized, so they bought back at a loss).
What I do remember for certain is that most of the bid side was pulled instead of being sold into, resulting in <50 BTC of bids at the lowest point instead of the normal ~300 BTC and high of >600 BTC. It builded up in minutes after seeing the initial flashcrash to 0.00280.
By the way, contrary to what many think, the higher lows trend has not been violated daily vwap-wise. The last low from August was 0.00305 and lowest during this bottom is 0.00310.
I was also online, pulled bids, sold nothing from this. Since then have bought more than those bids I pulled.
