Why do people keep saying this goes to 0? That is absurd. And it does NOT say it is designed to go to zero in the prospectus. Just stop with that.
In reality it may approach zero, but as long as there are buyers of the note, iPath will keep issuing them and following the strategy. It will just reverse split periodically.
People just need to stop with the talk of this being a "scam" and "manipulated"... it just isn't true. It follows a strategy, plain and simple. In general, this particular strategy loses money... but it is meant to be used like insurance... not as an investment.
