I am fine with short term tanking. I believe what is wrong with BTC miners (shareholders) is they expect unrealistic dividends for a quick buck. We are simply cannibalizing our own project to the point were it will indeed become unsustainable. A 95/5 strategy if successful will provide a sustainable (although much lower weekly dividend).

If 95/5 is not successful, then 99/1 would provide a 2% annual yield. It simply comes down to a question of how low will a SUSTAINABLE yield go before new BTC mining projects decide it is not worth it to hop on the mining bandwagon. Puppet is correct, the hosting fees and electricity costs also come into play in these equations. If the price of Bitcoin goes up it will help in these regards. One analyst I follow called Enky expects to see BTC around $3000 by the end of the year. Search on "Bitcoin Enky" to read his blog.
