Why people buying ASICMINER shares @ 4.6? 95MH/s per share? When 100TH will come online it will hold 30% ofthe network. ASICMINER 10%. For some period of time 100TH will be most profitable. Even @ 0.9B/share it will deliver more profits than ASICMINER.
As time goes on 100TH share price will decrease (to zero) while the Asicminer share price will (if history holds true) increase. You can't simply compare weekly dividends.
With 100TH you are making the bet that the total dividends will be >= the amount you pay per share.
With Asicminer you are buying into a solid long term investment that also happens to pay out ~25-30% APR in dividends.
Full disclosure... I don't hold either at the moment.
