Could you write a better contract that would attract volume?
The only indicator I have that there’s interest is that the forum topic I introduced over at Intrade has attracted 3X to 4X as many hits as the next biggest topic. It is by far most discussed topic in Intrade’s history.
In the case of certifigate, the extent of that disagreement is minimal. Anyone who's sane knows there's nothing to this certifigate nonesense. Only a tiny lunatic fringe would assign any value at all to it. I seriously doubt there's enough of them willing to risk capital to generate volume. The price would stay just slightly above zero, just enough to allow transactions costs to keep the sane people from slapping it down to zero.
