Update: Offer halted for ClarificationThanks for your interest and orders placed so far. Due to the unclear current and future pricing of the tier-1 BitFury distributors, I decided to halt the offer until those are sorted out.
I set the price based on what I paid myself for the chips and on informal discussions on the future price structure for chip distributors. It is also based on the current pricing of
80€ per chip at BFSB, which I expect to be cut by 50% as soon as October chips will be available. This obviously does not match with the price for the
400GH full kit of 6500€, which prices ready-to-mine rig at today's rate with 0.25BTC / chip. It either means that kits are not really available at the given price, or they are and buying bare chips does not make sense at all. I am in contact with BitFury and team to clarify and will update as soon as I know more. As far as I can tell, there will be a price adjustment - but prices for in-stock items might not necessarily be dramatically lower than for pre-ordered ones.
Meanwhile, my offer is halted. That is, you are welcome to place orders, but I will accept them only after I know the future pricing policy and only if my order is not worse than what you can get from dave or punin directly.
As for quantities and group-buys: yes, the unit size is 300 chips. That is the only way to limit accounting overhead and provide shipping and handling at no additional costs. Users sticking together and forming a group-buy to reach the unit size are gladly welcome.
As for what to do with the chips: there are several developers already who announced designing of BitFury based mining boards (e.g. burnin or bitmine). If requested, I can send chips ordered (only full lots of 300) to the developer of your choice for board manufacturing.
Cheers
I was gettin ready to ask you
