Topic: [Group Buy] BFL 4 GH/s Chips @ 0.65 BTC x5 min, US Only - closed (Read 4212 times)
ADMIN can lock/remove this thread. No longer open, no trades made.
I realize that buying credits, ordering chips and running a group buy is just not in my best interest right now. If you are looking for a chip group buy from a reputable member I recommend Canaryinthemine's group buy here: https://bitcointalksearch.org/topic/closed-bfl-4-ghs-chips-06-btc-per-chip-batch-29-236103
Will you provide some hardware assembly service?
As soon as a PCB design/DYI design maker that is trusted enough exist, I will facilitate chip usage for building of actual miners. YES
I am in the process of acquiring chip credits to cover at least the first 100 chips. Stay tuned.

I have 384 chip credits for sale for those without chip credits. PM me your offers.
Ok, I have now updated the group buy to reflect price using chip credits. Note that to purchase chips you will be required to HAVE CHIP CREDITS.
would there is a price drop accordingly 
I am looking into the possibility for using chip discounts for this group buy.
Yes. Actually, people that have chip credits can show their interest here and if it looks like we can fill at least 100 chips I will re-write the group buy to take into account chip credits, and also publish info on credit transfer with payment info.
That way this group buy would use chip credit orders only, and the price will reflect this ASAP.

All necessary schematics and software for producing miners using BFL chips has now been released. See original OP post for info.

if we can get the voucher discount that will be awesome
and i can buy couple shares
I have contacted BFL reg possibility of combining chips for purchase under 1 account. I have almost enough for the entire 100 chip purchase myself but would like to see if we can't combine a few accounts and maybe make the group buy larger, or at least have the option to do so.

maybe the group buy organizer can consider to incorporate the credit coupon and reduce the cost?
If i buy a coupon, how will i be able to use it if i cannot buy 100 chips from BFL as far as i know they require 100 minimum chip order
any updates regarding a working pcb for the chips
Josh released the chips specs and it can be downloaded from butterflylabs forum.

I bought 100 chips from BFL. Consider this: of all the miners/chips projected to come on line in 100 days ( bitfury, kncminer, avalon bulk chips, BFL, etc.), BFL is the only one that both has a working chip and is motivated by the fact that they will get the rest of their 50% payment on delivery. I believe that along with the fact that chips can ship directly from GlobalFoundries without being delayed within BFL's device manufacture chain gives BFL chips an edge over the others.
I have to wonder, 4GHz is fast, but in 100 days, will it mean anything anymore? I'm tempted to actually just buy 100 chips myself and then sort out manufacturing that into boards later. However at the same time I can't help but wonder- 400ghz, will that be worth it once the time comes? What do you guys think?
I personally think that even with vastly increased diff, the difficulty will of course not increase exponentially. As long as you are buying next gen tech, diff will eventually plateau. If you look at diff/earnings historically I think the CPU/GPU boom is relevant. We are Just seeing the same technological paradigm shift from GPU-->ASIC. If you buy the latest generation ASIC now, it will earn you money as long as it is the latest generation tech available, just as GPUs did until ASIC started hitting the market.
I think that is a pretty good way of thinking about it.
