It's hard to tell given how new all of this is. We have to let transient effects die down before really appraising the economic model. But, folks seem to be selling their SBD now and it hasn't disrupted anything as far as I can tell. Clearly the price will go down if more is sold, but that's to be expected. In the end we'd expect some sort of balance between buyers and sellers, as in any market.
