there are few sellers, hence the lack of volume.
Currently there's been not much volume (until a few hours ago), but the tale of the decreasing volume is flawed! Take a look at the cumulative volume graph across the exchanges:

ya vol is becoming more spread out
+ we don't count the economy which has been growing by leaps and bounds, sure alot of it makes its way to the market really fast but alot of it dosnt, we don't see the 50K$ deals behind the scenes, its happening.
