I agree with you that since ASICMINER is a bitcoin-based system, (deals in bitcoin mining, sends dividends in bitcoins)there's no point in thinking in USD value. It does not matter much what is the price of BTC in USD or whatever other fiat currency for the price of ASICMINER shares.
Right. You and I agree on that.
However you still haven't proven your initial point in saying the ASICMINER shares are overpriced. Wherever I look (BTCfunder, btct.co, bitcointalk.org auctions) The price of the shares is 0.8 or higher. So say whatever you want to say, the market for the ASICMINER shares says that the shares are worth a lot more than 0.6 which you said was too much.
When a stock is said to be overpriced, it does not mean the market does not want to buy it. It means the fair value of the stock (I estimated 0.25-0.4 BTC) is lower than the price demanded by the irrational market (0.6+ BTC). The vocabulary I use ("overpriced", "fair value") is well defined. It comes from the investment philosophy called value investing. So, again, the fact buyers are willing to spend 0.6+ BTC does not mean 0.6 BTC is a
fair value by the definition of this term.
Now, the only debatable point is what is the fair value of the stock. And one must attempt to estimate it by looking at assets and present and future revenues, like I did initially to prove my point: see

Mausini: your thought experiment merely shows their valuation would decrease a lot faster if their operating costs were a fixed amount of BTC. It does not show their valuation would increase if the costs are paid in USD... This is at least the 3rd or 4th time I explain to you their operating costs are only ~3%, that they can't go lower than that, that the USD costs are already as low as they can be, and that in the future this percentage will increase, a lot:

I don't know how else to explain it. There must be a comprehension issue that you are not raising to me (is english your native language?)
