There is no one to buy it right now. That is why the Fed and European Banks stepped in. Banks were afraid to loan to each other because they were concerned about solvency of the other Bank. I mean they know how messed up their stuff is. The top 5 banks own 97% of this stuff in some way or the other. Either outright or have invested or sold a derivtive associated with this.
I have no idea how it all works nor when or even if anything will happen.
