MPOE-PR: you really don't get it do you.
I own a house, buying an ASIC does not give me any overhead costs storing wise. I just put the damn thing on my desk. I don't need to move to a bigger house to give it a dedicated space, I don't need an I.T. manager to run it, nor do I need to have the electricity company to come by my house to give me an extra fusebox.
Am I wrong not to assign part of my mortgage or rent or cash purchase price of my house as overhead costs to my ASIC? If I would live in a theoretical bubble I might be inclined to do so, but I live in the real world and when I buy a table I don't add any 'storage' overhead costs to the retail price because it needs to sit in my living room. That's my cost of living and it does not go up when I buy an object I put in my house.
Electricity costs are obviously a different subject as an ASIC would add to my electricity bill.
Friedcat has to physically rent a space to house 50TH worth of ASICs. If he adds another 200 TH he will probably have to move to a bigger place. Although the rent for a warehouse might be lower per sqr mt for a bigger warehouse than for a smaller one, his storage costs will never be zero, like they are for my lonely ASIC on my desk.
Same goes for setting up and running the ASIC. Friedcat and his partners are getting paid for maintaining the farm and they probably (hopefully) have taken into account any additional personnel they need, the need for high end cooling, etc, in their own business plan. Once they expand limitlessly they are going to need more and more people to run their farm, bigger space and better cooling, potentially cutting into their profits. Not to mention they might become a target to a cyber attack (because they are a high profile target), for which they have to pay a lot of money to their data centre to avert.
Again, it will be highly unlikely that my lonely ASIC on my desk will be targeted by anyone, I can open up a window to cool things down and I am more than happy to download each new version of CGMiner and install it in my spare time.
So from ASICMINER's perspective it might be at some point be more profitable to get BTC upfront by selling mining gear, thereby creating a certain ROI for their investors and themselves, than to keep expanding their own operations, while it will still profitable for their customers to run the ASICs they buy off of them.
And lastly, I don't know where you live or what sort of friends you have, but none of my friends have thrown up in my house for the last 20 odd years, neither did I have a break-in or fire. Maybe I have just been lucky
Anyway enough derailing of this thread. Friedcat is due to give us a more detailed update, so let's hear it !!!
