The United States Securities and Exchange Commission (WOT:unpersons) has denied a petition by a venture calling itself "SolidX" (WOT:nonpersons) to trade a paper security simulating Bitcoin on US markets. This follows the same group's denial of a similar petition by the Winkelvii (WOT:unregistered eukaryote) to list a paper simulated Bitcoin instrument. Sorry for your laws.
So solid. Realsolid, solidcoin, solidX. Super solid.
