But the truth is that after the April, 10th crash we had days with HUGE volume. Damn, we had two days where we had ATH volume. I really believe the bigger sell off has already happened - and that was April, 16th, where we had +BTC550k sold. I could bet we won't have a single day with that volume in the next month, unless something really disruptive happens (I mean a really big technical problem, etc.)
To the degree that this bubble collapse behaves like the June 2011 collapse, it is normal for the big sell off to happen first. That's why I dubbed the August , 2011 capitulation The Great Capitulation of 2011. I believe the drop from $145 to $80 is the corresponding Great Capitulation of 2013. If my ideas are correct, then its likely we have seen the worst one this year.
Here is what happened with regard to volume back during the collapse of the bubble in 2011 ...
