Auction - yes, definitely
Every item - not so sure.
Look, we are talking about ~200 TH/s. That's 660 000 chips per 300 MH/s. Part will be small units (1 chip) and part will be 21GH/s boards that are currently deployed.
Who will manage thousands and thousands week long auctions?
I think optimal way to determine price is to do 10 (20?) week-long auctions on first machines. And sell others with that price directly (without auction).
You think 200TH will be sold? I dont know if thats the case but i think that would be a huge mistake. Firstly it would bring so much TH into the net that asicminer mining revenue would drop dramatically. But the worst thing would be that selling 200TH would need very much money spent from the community. Think about it this way: A Avalon asic with 65GH only sold for $25000 on ebay. That means you would need to sell 3076 units with 65GH. For a total price of $76,923,077 or 1,025,641
BTC (when 1
BTC=$75). And i believe it wont be possible to sell so many units or Mining Power for a real good price.
So i think Asicminer wont sell so much. I might be wrong but i see a problem there. Leading to units selling way under the price they should get when less units were sold.
I would like to know how long it will take until Asicminer can resume deployment though. It cant be too long i hope. If that happens it wouldnt be necessary to sell very much TH anymore.
Auction seems like a good approach for price discovery. One would expect the price to approach the net present value of future mining profits of the most optimistic difficulty forecast. Assuming that price is achieved, it would actually be a considerably better deal to sell
all the equipment rather than mining with them ourselves - especially if ASICMINERs expectations for difficulty are lower than the most optimistic forecasts of the mining community.
Then gradually as the most optimistic difficulty forecasts become more realistic, the price achieved in an auction will decrease - but ASICMINER can anyway keep selling until marginal cost, so there's a considerable profit to be made until that point.
