DNDN - Not sure what Feuerstein was responding to in that twitter - perhaps on of the huge number of Seeking Alpha 'articles' written by message-board enthusiasts (aka pumpers)?
As for the value of DNDN - IMO somewhere between 5 and 10. Immediately after the reveal (aka giant cratering of stock) I thought nearer 10 based upon my estimate of eventual cash flow, but upon thinking about it think it needs to be lower to account for the management.
