I would rather see evidence then hear about his epiphany.

 
I'd suggest you politely ask Josh for a tour then.

We offered him a liter of Tokaji Aszú a day to keep his silence in a special underground wooden "barn." Rumor has it, he's down so deep, his games of digital solitaire are never interfered with by cosmic radiation.

Those are the only clues he gave. It sounds like they threw him in some Hungarian volcano. We'll never find him.
Odd, I got a PM from PG stating he was alive and well in Sandwich, IL.  Is that where the Hungarian Volcano dumps it's refuse?

344  Bitcoin / Mining speculation / Re: PSA: Do NOT buy Bitfury BF1 USB Miner - It will not ROI. on: September 14, 2013, 01:58:12 AM
$110+ per GH/s is bad value, even the BFL products from April were $50 per GH/s or less. The developers of the thumb would have known this in advance before they started the project.  The current market expects $20-25 per GH/s to break even.

What people forget is that Bitfury 55nm chip based miners have to get a positive ROI within 6mths or they will start making a loss at current BTC prices, the cost of electricity will be higher than the BTC they produce.

Punching the numbers into the http://mining.thegenesisblock.com/ calculator tells me at 2.1BTC the unit will make a loss of around $160, which is more than half it's purchase price. In order to make a profit BTC/USD would have to rise to over $300. In which case it would be better to just hold onto your 2.1BTC

The unit which costs you 2.1BTC will only return 1BTC before it can't cover the electricity price, therefore it should be priced at 1BTC or less.




How many hundreds of articles do we need to see showing that the math just doesn't make sense.

Bitcoin mining, in it's current form is DEAD! BTC
Bitcoin mining is far from dead.  Bitcoin profitability is in the toilet, but hey, it started out that way.

The get rich quick seekers will soon sell off their mining equipment to the altruistic who will keep the network alive.  Look at the people still mining DEVcoin.
345  Bitcoin / Mining speculation / Re: Bitcoin: On our way to a Petahash on: September 14, 2013, 01:50:07 AM
Actually we're heading towards a exahash.

Reasoning: those upcoming  28nm chips produce ~500GH and my guess is ~$30 is roughly the price at which they can still be sold profitably (that includes basic PCB,  housing, minimal markup; variable cost of the chip alone is probably closer to $10 in large volume). So as long as there is demand at or above that price point, it makes sense for asic vendors to sell (or produce and mine themselves). If you do the math at what point most miners would no longer be interested in buying 500GH (250W) for ~$30, depending on electricity cost and BTC exchange rate, I get at a difficulty on the order of ~100 - 200,000,000,000. Which means a network speed of roughly a exahash. Thats where we are headed IMO, though Im not taking any bets how long it will take. Could be as little as 2 years from now  to get close to that.


Excellent reasoning. I think you are on target. It would be very interesting to get a leak on how much chips actually cost at manufacturing (28nm for example) to get a base seed value for your estimate.



Im basing my guestimate on the embedded SoC market. A typical highend phone SoC sells for about $15 in large volumes. That is when you buy them from nVidia (qualcomm, samsung etc)., so these companies already have a margin on that, fabbing cost will be lower. OTOH  28nm mining chips may be a fair bit larger than mobile phone SoCs, I dont have any size data (does anyone?), but they should also be a lot more simple to produce and validate, contain less layers, far less IO pins, etc.

My guesstimate may well be off by a factor 2 or 3, but not likely more than that, and so should still give you a ballpark idea.
How does that $15 phone compare to an $1100 i7 4930 processor?  It doesn't.  Neither does it compare to 28nm mining chips.  You're talking a drop in pricing by over a factor of 100 in less than a year.  AM's overpriced toys have only come down by a factor of 20, but he started out so overpriced PT Barnum is bowing in his grave.

1 Exahash = 2 million 500GH chips.  That's only 2x what Avalon had 'on order'.  780BTC for 10,000 chips = .078BTC per chip... and these were 110nm chips.  I'm sorry, but I cannot see a more than 4x reduction in size for ~3x cost in that short a time. 
346  Bitcoin / Mining speculation / Re: If Bitcoins Go Up Will USB Bitcoin Miners Be Profitable? on: September 14, 2013, 01:01:09 AM
So what price would a USB maybe be profitable? BTC.1, BTC.05, BTC.01?
At the moment... BTC.01 or less.

.085 after 6 months

Thanks for disproving your own claim.  Smiley Even assuming no slowing in difficulty growth, in the next six weeks and waiting a week for delivery, and subtracting 0.05 BTC for power cost the unit would produce 0.08 BTC net revenue.    Clearly 0.08 BTC is > "0.01 BTC or less".

True, but I still would not pay more than .01 for one of them.  AM has apportioned supply to regulate demand and milked every penny out of his victims err customers.  Obviously he is still making a fairly decent profit if he is able to sell them at the prices he is.  .1 BTC per chip still works out to $42 per GH as of today's prices.

Is it possible he meant that the assembly of mini-rigs up to the point where the boards were needed continued until the boards arrived, thereby there was no work stoppage on the minirigs?
Nah... that makes sense.  Can't introduce sense into this conversation.

 *Mumbles something about nothing making sense with regards to Butterfly Labs*
 
Must.....not.....poke.....the.....bear.....bah

Just cause you couldn't keep your trap shut for 38 more days.....

They reserved the right to refuse service, and acted.

Are you literally retarded? BFL gave him free money by canceling his order (Well, freely gave him back his money).  Would it have even shipped by now if they hadn't?

Do you think he wishes he had an order with BFL at this point in time? Or at any point in time in the past several months?

When you read your posts it's like you have no idea people actually like money and get upset when it's stolen from them.
You don't do any research and call ME retarded? Roll Eyes  It was a day 1 order.  Roll Eyes

At the moment... BTC.01 or less.

Seeing as a USB BE would generate more than that in the first week I think that is dubious.

At 0.1 BTC (or less) is is almost certainly profitable.  
At 0.15 BTC would likely take a long time (6+ months) and would require cheap power and difficulty growth slowing significantly in 2014.
At 0.2 BTC I don't see turning a profit under any conditions.
If I could get it in hand today, yes, I could make .1 BTC.  If it took 1 week to get it in hand, then it's looking shaky.  At 111M difficulty, it's estimated .05 after 1 month if difficulty doesn't go up.  I see .0015 per day for 10 days, .0012 for 10 days, .001 for 10 days, .0008 for 10 days, .0006 for 10 days, .0005 for 10 days.  .056 after 2 months, .066 after 3 months, .074 after 4 months .08 after 5 months and .085 after 6 months.  At 1Bil diff you're getting .000167 per day.  389 more days to .15 with no more increases, 90 more days to .1

It isn't their fault that mining is currently unprofitable unless you throw down a big heap of investment capital up front. The units cost what they cost to produce, end of story. If you don't like it then don't buy any. There is no need for a flame thread because you can't comprehend this.
Why not?  There's multiple BFL hate threads mainly due to the fact RoI is vanishing.  People keep saying if BFL had shipped on time and made mining unprofitable that they would be criminal for doing so.  Yet now we got to just get over it?  Roll Eyes

351  Bitcoin / Hardware / Re: Butterfly Labs 30 day countdown to the end of September on: September 12, 2013, 08:11:15 PM

In the one thread, I mentioned that using bfl.ptz.ro you could see that a minimum of 938 Jalapenos listed from Jun 23 to the end of Jan along with where the other lines were.  I felt we could triple the total and get a good lowball figure for their shipping to date.  That would be ~3000 Jalapenos which was kind of scoffed at as too high.  I then commented that I felt the true number of Jalas was closer to 7000(my gut said 10k, but I went with 7k) than the less than 3000 the others believed.  I straight up asked Josh if I was right about it being closer to 7000 and his response was yes, much much closer.  I would have to take that as meaning they shipped somewhere between 5k and 7k Jala's, which is the closest I got to actual numbers.


I did the math on the bfl.ptz.ro

For Jalapenos from Day 1 to the last ship date 2/14/13 there are 1063 orders. So you are saying that the number is about triple that?

Something tells me the factor for Singles is not Triple, but something less than Triple.

On bfl.ptz.ro the amount of singles from yesterdays shipments (nov 16 - 19) is 7 (seven)

Mini-Rigs (August 5-15) is 12 (twelve)
Mini-Rigs (July 18-20) is 3 (three)


Now in BFLs defense, Mini-Rigs take forever to assemble (I would guess) so if they shipped 15 to 20 yesterday that is probably full time job for 3 people.

However the numbers don't add up on Singles. If the factor was Triple, X4 or X5 - They shipped almost none yesterday.

That's all well and good, what baffles my mind is that Josh said YESTERDAY that they would clear to April 2013 in 20 days.

Is he so disconnected or is there some magic wand he has that no one knows about.

Triple was the estimate used before, I'm saying it looks to be more like 5-6x from Josh's answer to me.  I didn't ask about Singles unfortunately.

I do think you are fairly correct on the mini-rig build speed.  I know the one assembler was starting one when we left to goto lunch and a little over an hour later had finished that one and was about 1/2 way through the second.

I think the big thing to consider is that it takes 8 times as much to build a mini as it does to build a single.  I've thought about this a lot and something came to me today... when Josh was saying they could produce 400 units, what if he meant 400 boards?  When I think about the amount the binning place is supposed to send to Chicago each day, 5000 chips, if you only made 16 chip boards that would make 312.5 boards.  Since the LS only take 8 chips and the Jala 2, you could easily get up to 400 or more.

Another thing to consider, only chips with all 16 engines working go into the long boards.  Generally 60-70% of chips fall into this category.  If 30% fail at least 1 engine on 5000 chips, thats 1500 chips and that would potentially make 750 Jalapenos.  That number seems awfully high to me compared to the Jala's estimated numbers.  Maybe they've only been using the Grade B chips for Jalas, but that would mean there are a lot of unused C and D graded chips.  The other possibility is they are getting more Grade A chips than normal. 

I'm waiting for next weeks' shipping reports, after the new assemblers come online.  That should give us the best picture to date.  By Wed or Thurs we'll know.
352  Bitcoin / Hardware / Re: Butterfly Labs 30 day countdown to the end of September on: September 12, 2013, 05:02:41 AM
All very helpful and it underlines a lot of the facts and figures I have been discussing all along.

I always thought tripling the bfl.ptz.ro was a good estimate.

Considering the sheer volume they are outputting, I don't think that doubling assemblers would be enough but we shall see.


Help me understand the supply chain and the assembly.

A frisbee size wafer is produced by the foundry.

It gets cut up into squares

Whats the next steps and where do the steps happen?

Do the 4gh Engines get attached to the board at the same time as the rest of the electronic components?

Is there anything happening in the BFL building other than assembly (i.e. soldering, chip mounting to PCBs etc) or is that handled elsewhere?

It's 11:30 BFL time and no shipping update for today, so we shall see what Jody has to say tomorrow, just had to ship 16 days worth today! 

Somewhere I heard 55 employees, that seems high.



The bumping facility cuts the wafers into chips.  The binning process may or may not test the chips(I honestly don't know) but they are graded A,B,C and D.  Whether the bumping and binning are done in the same physical location or not I do not know. 

After the chips have been binned, they are sent to Chicago and the chips are attached to the boards.  The PCB boards are made elsewhere and I believe there is no backlog of boards.  AFAICK, Chicago only populates the ASIC to the board.  Since Chicago is able to use all the chips currently coming in, the binning process is the slowdown.  Chicago sends boards to BFL, and they assemble the units.  By my understanding they also currently use up all available boards daily.

So, no, only assembly.

I saw ~10 in customer service, ~8 in the burnin rooms, ~10 assemblers, 7 or 8 in a room I never entered, 4 or 5 that put post-it on finished units and like 6 in the shipping area.  Add in josh, sonny, maybe a couple managers... It was lunch time, so some could have been out.
353  Bitcoin / Hardware / Re: BFL Jallies on: September 12, 2013, 04:11:48 AM
I thought the hold up on Jally shipments was because they were outsourcing the production? That's what Josh suggested in their forum chat.


Josh did tell PG and I that the Jala's are being outsourced.  This other company will build them and send them to BFL to be burnt in before shipping. 
354  Bitcoin / Hardware / Re: Butterfly Labs 30 day countdown to the end of September on: September 12, 2013, 04:07:07 AM
So contrary to "tl;dr" I did read your posts.

Still have questions like:

What's your opinion of daily volume?

How many assemblers?

You said you saw stuff going out the door? Any more specifics??

Did you see anything that was contrary to what "the haters" have to say?

You mentioned something about 7000 Jalas, does that mean that they have sent 7000 since they started?


To be honest, daily volume was hard to estimate, I was told all of the wafers have been fabricated, but it sounds like there is a supply line issue from the bumping facility to the binning processor to the place in Chicago that populates the PCB boards.  IIRC, the binning facility is supposed to ship 5k chips a day, but had not come close to hitting that mark yet.  Maybe they are getting close as I saw 8-10 assemblers and Dave mentioned an additional 8 starting next week, Josh mentioned that they were farming out the Jalapenos to a subcontractor and if enough boards from Chicago arrive it sounded like Will might win his 2BTC bet.  It'll be close.

The building there is about 110 feet or so from front to back.  I was in the parking lot out front when the FedEx truck showed up.  When I had gotten to the back of the building I was looking through a space about a foot wide between the burn-in semi and the back of the building and could only see the driver carrying packages into the truck.  As it was 102 degrees and no shade, I only watched for a minute or so before heading back to the front where there were trees to stand under while waiting for PG.  As to USPS shipping, there were several of the 'cages' the post office uses there.  Josh said they fill the cages and that way the driver can just wheel them into the truck instead of making piles at the back door.  Saves time for all involved.

In the one thread, I mentioned that using bfl.ptz.ro you could see that a minimum of 938 Jalapenos listed from Jun 23 to the end of Jan along with where the other lines were.  I felt we could triple the total and get a good lowball figure for their shipping to date.  That would be ~3000 Jalapenos which was kind of scoffed at as too high.  I then commented that I felt the true number of Jalas was closer to 7000(my gut said 10k, but I went with 7k) than the less than 3000 the others believed.  I straight up asked Josh if I was right about it being closer to 7000 and his response was yes, much much closer.  I would have to take that as meaning they shipped somewhere between 5k and 7k Jala's, which is the closest I got to actual numbers.

I did see a timeline on a VAP board for gen 2, but as Josh told me it was not set in stone, I feel repeating anything I saw there would just cause more flaming.  I will say that I feel confident that they will have all 65nm product caught up before the Monarch is supposed to debut the end of the year, but that is merely my opinion after seeing them at work.

At the meet-up Tuesday evening, Sonny was there.  PG and I talked to him quite a bit and I found it interesting that they were originally working on the FPGAs for an entirely different purpose when someone brought the idea of using them for Bitcoin mining.  PG  was curious about the name Butterfly Labs and Sonny explained how the work they were doing before had something called a butterfly effect.  When you graphed the results, you had a fairly distinct butterfly shape.  It was an enjoyable get together and I personally found them very forthcoming on all of my questions, even the embarrassing ones I did not relate in full here due to my own discretion.

Excellent Meetup with Goat soon to provide pics. In attendance was myself, bcp19, boozer and a friend of his with his son, Goat with his lovely wife, Josh, and Sonny. While they all ate raw fish, I enjoyed a fully cooked cow. While they all got drunk and picked on me, I had coffee and took it like the passive asshole I am.

Seriously, it was extremely enjoyable, and I will be writing up an excellent review of BFL as soon as I get back home to Illinois. The review will not be influenced by the proverbial Kool Aid or the gift Josh gave bcp19 and I: A 60 GH/s miner rated at only 20 GH/s due to some subpar component--maybe the chip(s).

I wish to thank boozer for putting this Meetup together and BFL for picking up the tab.
All got drunk?!?!?  You were sitting next to me watching me drink water all night Tongue  Just cause I like the sinus burn from Wasabi doesn't mean I was drunk!

If you plan to take I-80, you'll travel through the state of Iowa. Without being too specific, I live in a city located along I-80 in the state of Iowa.  I'd love to meet you and help out if I can.  I may not be the only Iowan bitcoiner, but I have yet to meet another.  To my knowledge, there are no businesses that accept bitcoin in the state; however, I've managed to use Gyft to get most of what I need.  @LifeOnBitcoin, PM me if you would like my details.

I'll PM you. There is a high likelihood we will be using that route as we are going to Chicago. Can you try to get a local mom and pop restaurant to accept btc? We could do lunch with you on the way through to Chicago. Also, if you could talk to local gas stations, and get one on board, that would be awesome! I'll PM you later this evening.

Theron H.
I just saw your post, I also live in Iowa, but if you are travelling I-80 you'd miss my hometown.  I live about 1/2 hour north of the Interstate in roughly the center of the state.  I know from one of the in-person exchange sites that there is someone in the town to the west of me who sells BTC, but I'm not sure about any businesses as yet.  Good luck on your travels!

358  Bitcoin / Hardware / Re: Butterfly Labs 30 day countdown to the end of September on: September 12, 2013, 02:05:29 AM
@ bcp19
Scenario,
You just blew your two front tires on the road. Lucky for you, there a tire station at the end of the road called ADL.
Something PG mentioned while we were in KC made me think about this post.  It's something he and I went through but I doubt anyone under 25 would ever be able to fully understand.

When we were children, you used to have things advertised on cereal boxes that you could send away for once you had 6 box tops.  PG was came from a family with 6 kids, but for me if was just my brother and I.  We both usually wanted whatever it was and then we'd have to amass 12 boxtops to send in.  12 boxtops usually meant a good 6-8 weeks cause we were only allowed to take them from empty boxes.  Once we had the box tops, we'd fill out the order forms and might have to add a doller or so for shipping and then you'd mail it in and wait.  The normal shipping time on these was "Allows 8-12 weeks for delivery".  So, from seeing the product advertised to receipt was a minimum of 4 months, and this was for something they had IN STOCK.

The first deployment I made to Japan, I would call home once a month, a 30 minute call could cost around $100.  Imagine trying to hold a converstaion with someone where you have to wait 3-6 seconds for a response due to the time lag from going 1/2 way around the world.  We've made great strides since then, years later I could call from halfway around the world and there was no perceptible delay and it sounded like you were calling someone right next door.

"Instant gratification" seems to be the keyword.  You've got the commercials with people yelling out windows "It's MY MONEY and I want it NOW!!!".  Everyone's advertising "NEXT DAY DELIVERY!" and people regularly pay the premium to get it.  I recently ordered an old shop manual off Ebay and I could have gone with next day service for something like $25-30, but I selected the Economy shipping.  I placed the order on a Friday and it was in my mailbox Monday.  I guess that $25-30 would have been money well spent! (<-- yes, that was sarcasm)

My background gives me a better insight into the workings behind these companies than most people have.  I know well how theory seldom equals reality.  I've helped test new equipment many times over my career, and engineers don't often stop to think what people will do.  I remember one of the first touch screens we got in and they were showing us how it worked.  The person who brought it was carefully explaining how to bring this amd that.  Then one of the people who would be operating it sat down and asked "But what happens if I do this?" and he pushed 3 buttons at once.  The screen locked up and they had to completely power down the system and reboot it.  The people who create and build things never think to add safeguardslike this, cause they'd never hit all 3 of those buttons at once.

Patience truly is a virtue.

I already stated elsewhere that when I got there around Noon I saw the Fed Ex truck pull up and when I walked back and looked he was loading packages(wasn't going to crawl into the truck and count).  I also already stated that Josh told us that USPS, UPS, DHL and Fed Ex normally pick up in the morning and when we got to the shipping area there wasn't the 4 day stack of packages PL thought they'd roll out for the 'dog and pony show'.  They did have 3 burn-in areas and a 4th was under construction.  It was very neat to see the over-sized semi-trailer they use for one of the burn-in areas... Josh mentioned it used to be a military command and control bunker complete with generator and HVAC.  I didn't get a chance to count, but they had quite a bit burning in that I could see.

Ok, well surely you saw a team working on the Monarch. What did that look like? With the tape-out in Aug '13 they must have some cool stuff going on.
I honestly don't remember much being said about the Monarch... Having spent 20 years in electronics, I was more interested in the assembly area.  If Josh had let me, I'd have sat down and started building one Smiley
