I'm not sure that's enough of a sample size yet. The beginning of the IPO period may not be a fair indicator of overall demand. I think average demand could settle a little lower than this, since some people were eager to get in on it. But there's also a strong possibility that "we ain't seen nothin' yet." If BitShares marketing and BTSX really take off in the coming weeks (before early December, when the Music fundraiser ends), those coattails could really lift Music's IPO donations as well. And if there are even a couple of well-placed articles on BitShares Music/PeerTracks, then people would understand just how exponential this DAC could become.
I can't wait to see this DAC in the Top 10, because it is such an awesome concept and model. I think it's going to attract a LOT more demand, either soon or over time.
