H boards are out of stock, wow.

Nice! less people will loose money on them Smiley

spiccioli


with starter kits paid over 1000 $, I guess that a lot of people already did loose and is just trying to recoup something.

I already had positive ROI on my August starter kit. No idea why you guys would have a problem.

Full August kit, paid around 310 BTCs, up to now has earned around 114 BTCs, it will NEVER break-even.

Guys,

there are only two kind of pools:

- too big
- all the other pools.

Choose wisely, choose a smaller one and in doing so:

1) - help increasing bitcoin network health: DE-CEN-TRA-LI-ZED means nothing to you?

2) - be a bigger fish in a smaller pool (instead of the other way around), remember: bigger fishes eat smaller ones.

3) - please do understand that all the hardware which was bought in the last four months and all hardware being bought from now on is NOT going to break even, so pool choice makes no real difference FOR YOU but can make a difference for bitcoin network health, see point 1)

4) - a better bitcoin network health can help increase bitcoin value and in doing so can help you earning more from your investment.

Variance means that some days you get less, but some other days you get more and the days when you earn less are LONGER than the days when you earn more, so be patient!

A smaller pool is easier to monitor, a smaller pool has to have smaller fees, a smaller pool is more enjoyable to join since you become part of a (smaller) community of miners which share your same goals.

Stop being a lemming, start mining somewhere else!

wow add VAT and see how much you get out..... overpriced for me, I was expecting cheaper hardware after the successful run they had and the positive experience.

A KnC Jupiter is definitely cheaper now at 4995 USD instead of 5700-5750 USD for a full rig made up of 16 h-boards + 1 m-board + 1 raspPi.

And h-boards are "certified" at 25GH/s, so you could end up with a 400-450 GH/s bitfury unit instead of a 500-550 GH Jupiter if you're unlucky and get underperforming cards.

ps. the whole bitfury's idea was a lot of "small" chips against a few big ones... but if small ones are priced like this, the whole idea does not work so well.

245  Bitcoin / Hardware / Re: [ANN] Bitfury ASIC sales in EU and Europe on: November 05, 2013, 03:27:19 PM
H-Cards in the shop :-)
With lowered price. Interesting to see what price will be in January Wink
Now is more resonable to buy H-Card and desolder chips if you want chips cheaper Wink
Hmm lets count.
Chip in reel cost 15eur
Chip from H-Board 15,63eur


boards are not free...

ps. plus VAT

To answer some PM questions
- I don't have physical access to the miners, anotherhost is a secure facility with government and law enforcement clients.  No unauthorized entry, no photographs, etc
- I have never seen any of the units, I have no idea which production line stickers they have.  They were all day1 so most likely have 8 VMUs as they were delivered before the manufacturing change


Nice, now let's start talking about a fair price... Smiley

hopefully the price will be set <2BTC at this point

+1000. At least for returning customers, I would buy a bunch then..

August customers should (deserve to?) get a special price... punin what do you think? Smiley

251  Bitcoin / Hardware / Re: HashFast launches sales of the Baby Jet on: October 30, 2013, 06:51:41 PM
I like the approach taken but the scale is simply unrealistic. For the sake of the argument lets assume the chips (silicon & packaging) is possible at $0.20 per GH/s ($20 per TH).  Small runs (less than 1,000 wafers) at 28nm are probably more expensive than you think but lets ignore that and look at the rest of the system.

For example lets try to guesstimate the balance of the system (everything but the ASIC) on a Sierra.  Here is my guess what is yours?
case: $60 * 1 = $60
watercooling: $80 * 3 = $240
case fans: $10 * 2 = $20
power supplies: $150 * 2 = $300
PCB (both PCB manufacturing and assembly):  $30 x 3 = $90
DC regulators (12V to ~0.8V 200A output ea, 2 per board): $30 x 6 = $180 (probably more KNC uses >$300 per 400 GH/s system)
minor components (connectors, capacitors, etc guesstimate 100+ components per board): $50 x 3 = $150
labor (post PCB assembly, testing, packaging): $50
Balance of system (excluding ASICs) = $1,090 or $908 per TH/s.

That is nothing for fixed costs, markup/profit, yield issues, customer support, shipping losses, warranty, etc.

Now say you could cut that in half and had free raw chips that is still >$5,00 per TH/s.  Maybe with enough volume and streamlining you get the cost down to $250 (and assume no yield losses, customer support, profit, etc).  Personnally I doubt it but maybe.  However your charts starts at $250 and go to just silly numbers like $50 per TH/s.  That would be $60 per Sierra equivalent (or $25 per KNC Jupiter).  Say I gave you 1.2 TH/s (or 0.5 TH/s) of free chips show me how the balance of the system would only be $60 or $25.   Pay close attention to DC regulator (VRM) costs and power supplies they are more expensive on a $/GH basis than you might think.

The power axis is misleading because power in = heat out and then it takes more power to remove the heat.  So even an generous (I would say unrealistic) 8 cent per kWh, 20% cooling overhead (PUE 1.2), no real estate overhead, and $500 per TH is more like "end game" of <225 PH/s at current exchange rate.  Kinda shows how silly projections of >650 PH/s in less than a year.

i recently did my own guesstimates of the cost and came to very similar conclusions, though i think you're on the low side for the actual asic costs, but i think you've overestimated the power supply and cooling costs, as they appear to be using relatively off the shelf parts, which will be in volume production and they're not paying retail prices for them.

I think this is very critical, because what it shows is what I've always been saying, that the cost of the system is mostly "other stuff" (psus, cooling, case, pcbs, fans) and not the actual cost of the asics, thus you get enormous cost/performance improvements by having faster asics, as the rest of the system doesn't change in cost at all if the asics went faster!

And to reduce the cost of that "other stuff" bitfury did try to build minimalistic PCBs, but so far has had some problems...

p2pool.info is best at any time because of it nature!
- 0% fee
- PPLNS
- tx fee for miners
- decentralised (ddos impossible)

HHTT is on a par on a lot of things and easier to setup:

- 0.5% fee (p2pool has a default 1% fee to its author which you have to disable if you want to be 0% fees)
- PPLNS
- 1/2 transaction fees for the miner who solves a block
- high availability and resiliency (I won't say it cannot be DDOSed... but a lot of p2pool nodes could be easily).

253  Economy / Computer hardware / Re: Black Arrow offers IN STOCK hashing solution based on Bitfury 55nm ASICs on: October 29, 2013, 07:49:00 PM
black arrow stays self moderated...I'm seeing a pattern here.


The only pattern I see here is that this unit is going to ship four months from now after HF, Cointerra and BitMine which is going to deliver 2 TH units at least two months before them (if all goes well) and in the meanwhile KnC and BitFury could deliver (OR increase their mining operations by) petahashes like there is no tomorrow.

Avalons were sold in October 2012 and delivering started at the end of last February, but they were priced at 1500 USD.

So, at 2000-2500 USD I'd probably buy a few edit: prosperos right now, but not at 4500 USD.

BTW, when does Chinese New Year happen  in 2014?

spiccioli

ps. Sorry blackarrow if I'm sounding rude, I appreciate that you're trying to sell on stock items, sadly it is not enough anymore, too many ASIC vendors right now.
254  Economy / Computer hardware / Re: Black Arrow offers immediate hashing solution based on Bitfury 55nm ASICs on: October 29, 2013, 07:11:38 PM
too expensive. it's more than BFSB sold their h-cards 2 month and a few huge diff. jumps ago.
do your maths guys!

Yeah,

144 GH/s should go for 9 or 10 BTCs to have any chance of reaching break-even.

255  Bitcoin / Hardware / Re: [ANN] Bitfury ASIC sales in EU and Europe on: October 29, 2013, 01:30:00 PM
Yep, I ordered one to pimp up / tweak some boards ... without taking down the whole miners ...
... the whole overclocking gets much more relaxing ... the price is fine ... the shipping cost ...
are quite expensive for a single product order ... but who cares ... as long the fun is in the game

So, no more h-boards from now on?

Just chips?

Variance, look at 30 and 45 days luck, one day is too little.

The other day we had 4 blocks... it can't be so every day Smiley

edit: you can have a look at a comparable size pool's luck and you will find out that, sadly, at this pool's size it can and it does happen to go a couple of days (and even more) without a block.

Hi guys,

I haven't had a pplns owed amount added to my account for 2 days now.  Anything to worry about?

Pool hasn't found a block in last two days...

and

Payouts

Payouts will occur based on the following rules:
If the balance for an address is greater than 0.25 BTC, a payout is done.
If the balance for an address is greater than 0.05 BTC and the last payout was more than 24 hours ago, a payout is done.
If the balance for an address is greater than 0.001 BTC and the last payout was more than 3 days ago, a payout is done.

Payouts are automatic and cannot be requested. These rules are run at the start of each hour.


So, the old ugly variance at work Sad

I am laughing at this (on 2014/11/05 ) 91,637,018,622, You honestly believe it will reach this Number by that date? again lol if you do. If I am wrong then a big ol LOL in general because that's some insane network hashing power to produce that diff.

You don't need to reach such a high difficulty to be completely unprofitable on a 6500 USD/450 GH/s rig.

A 16 bus M-board may be in the works - this will make just about anything run - noisy cards, EOL's, etc.  Maybe these 8 chip boards would be sellable at that time...not sure.

Nice idea, this would solve a lot of problems with current systems, I have two of them from BFSB in Europe.

Would it cost a lot more to make a 16 bus board?
