Well hoarding is always a problem, but perhaps there are just too few of them to not hoard, if you know what I mean.
EDIT: how fast is the supply increasing?
Daily supply should be about 12k or so.
edit: Specifically, I was referring to the supply going to market .. not the daily supply mined. If someone's willing to pay me almost 2x as much as what I had yesterday for something .. I'm probably gonna take that deal. Especially if I have the ability to sell off parts of what I have rather than the entire thing at once.
