Looks like they're not seeing the mystery candles for 10-80k coins happening in china with clockwork regularity, nor the repeating orders on bitstamp that barely move the price, nor the complete dearth of action in the intervening periods.
To use raw volume numbers reported by the unregulated exchanges as the sole basis for a trade sounds to be something other than "experienced".
For the last two nights I watched about 6k coins quickly thrown into a 25 Bitcoin wall at the quietest time possible on Bitstamp. The price barely moved by a dollar. Apart from that the volume was almost none-existent. It's funny how it happened when most people were sleeping. Exchanges faking volume makes me so angry.
