To a long time holder, and even to a speculator. There will simply not be a sustainable price advance if volume (=people wanting the freakin' bitcoin) is not there.
I'm sure you agree that the relevant volume here is USD (since that's the ressource we need enough of to maintain or raise btc price). Hence: "Volume in currency" in the following chart:
Looks good to me. Between 2 and 5 times as high as in March (when the price approached 40), and 10? 20? as high as in January, February. Maybe not the volume to support a price in the multiple 100s, but enough to support 100, 150? Why yes, looks like it to me.
