I don't think at the moment there is any model that can even determine the fair value of a share of AM within an order of magnitude. There is just too much we do not know at this time.
And yet STILL you cling to your irrationality! Bitfunder currently suggests a share price of 0.75/BTC, a price at this point still looks fairly generous to me.
But your assertion is that we cannot rule out a value of 7.5 BTC per share! That would be equivalent to a market cap of 3 million BTC, or 25% of the Bitcoins in existence.
This, for a company currently struggling with 1-2% of the hashrate and no competitive 2nd gen chip announced.
He also means that we cannot rule out a value of 0.075 BTC/share. Chillax.
