Welcome to the group Kushedout. When you get a chance, could you verify your bitcoin address (12hv7UcFgrBWLjWs5McPYP63Yza6ufT6Sw) by sending us a signed message, as described in the OP + 2nd post? This will ensure that signed messages are working in case you need to change the payout address etc. later.

OK, got it, thanks. I'll pm the two pledgers now and suggest that they make their contributions within 24 hours or we'll have to open up their shares again. Hopefully we can get this component ordered tomorrow.

Got it, thanks monkeynutts, I've updated the OP with your payment address.

OK, now all the distractions elsewhere are over, it's onto the next board for me.

The collection for H-board #5 is now open

Now 8 / 10.39 shares remaining for next component (at current BTC rate shown in the OP)

We've just asked John K to order the next component and will update here when it's officially ordered from bitfurystrikesback.

Unless there are any objections from group members, once H-board #4 is ordered and we've done the calculations based on the BTC:Euro rate at time of ordering I plan to amalgamate the fractional shares from components 4 and 5 to make a whole share (plus a remainder probably) and open this to the group. I think the fairest way to do this is to issue it in component 4 and shift the list of shares down by one share. An example of what the list would look like if we did this is below to help explain what I mean. Please let me know if you have any thoughts on this?

Edit: it may be necessary to amalgamate fractional shares from more than two components.

Hi All,

We would like to gather opinions from group members and potential group members about whether or not to diversify this GB to include a different hardware supplier in addition to bitfurystrikesback. For those of you who have followed the Avalon chips disaster story you will know that burnin designed and assembled a very nice board (the bitburnerXX) for Avalon chips (https://bitcointalk.org/index.php?topic=179769.0), but that this project was hampered by the big delays in chip deliveries from bitsyncom. Burnin proved himself an excellent hardware designer and a very honourable person to order from during this project. Burnin has recently announced that he will sell a bitfury-ASIC mining board (https://bitcointalk.org/index.php?topic=283992.0), which should cost around 470 Euro + VAT (19% in Germany) and should give > 40GH/s. It appears that his delivery estimate for these is early October. We already have a personal bitburnerXX order and it seems that as existing customers we will have earlier access than the general public to order burnin's new bitfury boards.

Could you let us know by posting here whether you think that the group should switch to collecting for burnin's bitfury miners rather than additional H-boards for a while? We always have the option of continuing to collect for new H-boards again if the price of these changes and makes them more attractive (in terms of GH/s/BTC) than burnin's offer. We would anticipate that any new hardware being ordered for the group would be added to the total mining power of the group (and not to individuals who have contributed to that component) and mined BTC would be distributed in a similar way to the plan that we outlined for H-boards. The details would need to be finalised (and posted here as supplementary terms and conditions) if we decided to go down that route. Your comments and suggestions will dictate what the group does next.

To get you thinking, here are some data:

H-boards (25GH/s): October delivery: 390 Euro + VAT = 483.6 Euro = 5.37 BTC (at 90 Euro/BTC) = 4.66 GH/s/BTC
Burnin's furyburner (> 40GH/s): Early October delivery: 470 Euro + VAT = 559.3 Euro = 6.21 BTC (at 90 Euro/BTC) = 6.44 GH/s/BTC

First thoughts:- I'm glad I wasn't involved in the bitburnerXX scheme

The hardware on offer seems to be standalone boards, rather than direct plug ins for our M-board (expected in October). So they would need a power source, fans, and some sort of physical support. Does jlsminingcorp have these available, or would part of our money be used for these parts? I'm assuming the useful life time of a PSU and fans is far longer than the mining boards, and don't favour buying new equipment. I do have a spare PSU that could be used if it is required.

I don't see that the >40Gh/s speed is guaranteed, rather it seems to be a design goal. End-user overclocking also appears to be a design goal, so final speeds will probably be variable from board to board, and dependent on PSU and cooling efficiently, as well as the end-users views on safe chip temperatures, life time, and general gungho-ness. Does jlsminingcorp have any experience in overclocking similar hardware?

Do I recall that the equipment will be in a domestic setting? I hope there is good ventilation since I imagine these boards will surpass GPUs in the heat produced.

The timetable is unclear, as one might expect. But it seems that CryptX will be handling all the sales and marketing and there is an implication, but no promise, that they will inform people with existing Bitburner orders before the public "We will sent a mailing to all the Bitburner clients with the exact launch moment." also "Prices and Hashrate will be made public at the moment of the launch." (People with existing Bitburner orders also get vouchers as part of a complicated refund scheme). My impression is that the window for purchasing could be short, and so having the funds available to move quickly would be important. (I'm thinking back to the order of the August Bitfury Starter Kit, which sold out in less then 24 hours.)

In these days of difficulty increasing by 30% every ten days, the thought of getting a faster board in early October is very appealing, and I would be happy to invest.

My usual preference is always to keep financial schemes simple, so wonder if this might be better organised as a separate group-buy. If that isn't a viable option, or if the group decides against it, then I would like to see a worked example with some assumed dates, difficulty, and expected payouts, because I get muddled when I try to work them out! Perhaps a spreadsheet so we could all tweak the numbers and see what effect delays or poor hashing rates have.
