There is no mechanism to push the price of SBD down quickly (i.e. no mechanism to rapidly expand the supply of SBD), so it can be pumped up rather easily. In time, it will drift back down to about $1 -- either as the bagholders that bought at $1.20 realize their mistake, or as its supply gradually grows to meet demand. Back in March it momentarily hit $7, and then eventually it came back down.
