you're confused about what liquidity means
Are you referring to my preferring to consider USD volume? If so, I'd like to hear your thinking there. It'd be pretty amazing to see both, BTC volumes from a year ago and today's prices right now. Yet today, selling enough to, say, buy a house compared to selling the same a year ago isn't a very big chunk of the daily trade volume.
Or maybe you take exception to my ribbing about the general idea here that speculation should increase liquidity, therefore decreasing volatility. I could have phrased that better to begin with, but my point was: if that's true, then given the barrier to speculate has now been significantly lowered, volatility should decrease. I guess we'll see!
