There are two options though, gpu miners will quit, btc price will rise as it already has.

Or BTC value will fall,  when the GPU miners ( the largest user base) stop using BTC.

The Assman: CEO of Vandelay Import/Export, Inc.
So one chip would be about .1 BTC. In 100 days who know what that will look like.

Difficulty is estimated to be ~200%+ higher in 100 days (using historical 10% weekly difficulty increase as prediction). If my math is right, that means the same hash power at that time will be minting only 0.029 BTC per day.

I really can't imagine it's going to be worth it at all to run most of this equipment after another year. Assuming the 10% weekly increase holds, difficulty should be about 2.4 billion at that time and even Avalon 70 Gh/s miners will fail to mine half a bitcoin per month.

Shits a changin'.

Can I just clarify that the cost per chip is $75 and each chip gets 4GH/s.
I am trying to get my head around the costs and potential revenue.

I run at just under 8Gh/s with a Jally (which I believe has 2 chips) and mine about about .2 BTC per day. So one chip would be about .1 BTC. In 100 days who know what that will look like.

That is a hard one. What will happen with difficulty in 100 days? Who knows...

Hi Mrteal,

will you also be accepting orders for board assembly with chips supplied directly to you?

By the way, when you ordered, did the credits apply to the 50% deposit, the final 50%, or split between?

Thanks
Peterepeat, the details of that haven't been worked out, but it is something that will be in the cards. When ordering, the total cost is reduced by the $25, and then you pay the 50% deposit on the $50 ($25).

Thanks MrTeal.
I havent yet made the order as I would prefer to get them shipped to whoever is doing the assembly and not to Australia to avoid unnecessary delay and costs. I will wait on the sideline for now.
Cheers

Hey guys, the chip buy is closed. Please don't send me any more BTC or codes, unless you want to make a donation. Smiley

The buy was done today, so we're in the queue to get chips on their way. Thanks to everyone who participated or expressed interest.

If this is still open, I'd be interested in 4 chips and have a two chip credit.

Teal, you know its extremely risky putting money into this without any idea when the DIY boards available right?

Look at all the preorders from ASICs + Avalon chips, you dont have much time left.

I have enough chips credit so i dont need a groupbuy, i'm only interested in the boards.

ps. PM me where are you located in Canada.

Hi MrTeal,

PM sent: What's the deadline of the payment? Should I send by MtGox's market price?

[edit]
What's the order status at present? How many 100 chips batches filled for now?

The new transistors have moved back to OptiMOS series devices in the cooler running Jalapenos. I don't believe anything else has been done to the power supply circuitry.

IIRC, cooling was not the issue with putting 8 chips on the board. The issue was that the board couldn't give enough power without frying itself. The board was only originally designed for 60W, and the current Jalapenos are pulling 30-35W. You could throw all the giant heatsinks you want at that board, and it won't handle the 250-300W it would take to power 8 chips without frying itself.

crazyates,

So the PCB that BFL_Nassar released is for Jalapeno?

Correct. They haven't released the specs for the "Long Boards", which have the improved power distribution. They just wanted to give people something to work with.

I don't believe we have any plans on releasing the longboard designs. The point of us releasing the design stuff wasn't so people can just go make their own BFL stuff... it was so people can make new stuff.
