For me it is last drop - 3BTC or neptune that late is damn joke!
I'm ready to go as far as it is needed to get my miner or half of my investment back. (Deal was 2 for 1 right!)

What kind of joke is this?
Is this April Fools Day prank or what?

3BTC after waiting almost a year. Now they claim that they had some kind of error in their system? I hope that karma hit-s them hard to nuts!
Is it our problem that they messed up their system and lost some data?

Or neptune - AHAHA, now they want to get rid of old equipment and are offering that fire-hazard product?
Nice joke, KNC, now give us our Titan!

Deal done.  Happy customer.

Good packaging, good shipping speed from halfway across the world.

Thanks!!!

-EP

Thank you too - super fast deal!

I would like to thank our escrow service provider - "yochdog". Everything went smooth!

Locked!

200GHps Avalon for 4.8BTC = 0.024BTC/GHps
275GHps Saturn for 7BTC = ~0.0255BTC/GHps

When comparing the power consumption, the Saturn is way more efficient.

PS! ~200GHps BTminers (Avalon gen2 chips) are currently sold for 2.2BTC.
https://bitcointalk.org/index.php?topic=379819.0

I guess my fault for not looking at things too diligently.  I kind of just decided to jump in feet-first into mining.
Oh well.. it's still fun!
the avalon has 3 times less wattage/ghash rate

Yup. With Saturn you will be profitable for long time. I'm pretty sure that he will mine way more than 7 BTC + machine itself can be sold on secondary market any time. They are currently going with really high price (~$8000+) on ebay etc.

And yes.. Deal is done and i will lock this topic soon. I paid extra for fast delivery, so it took only 1 business day. EPiSKiNG is good customer and i got fast feedback from him to make it happen. Waiting for escrow release now.

some of our effort will be lost now.

Not all lottery tickets are winners.  Every share you submit is like a lottery ticket.  It's as simple as that.

We pooled our resources, bought several million lottery tickets, and none of them were winners.  Our effort was lost.  Bummer!  But, on average, we'll keep winning a certain percentage of the time, so I'm going to keep buying tickets.


No kidding? I don't want to win with every ticket. I'm not saying that.

"PPLNS - Pay Per Last N Shares. Similar to proportional, but instead of looking at the number of shares in the round, instead looks at the last N shares, regardless of round boundaries. "

PPLNS - is protecting miners from "lottery ticket" effect. Because in the long run probability to "win" is as high as your hash-rate is compared to networks.

All i want to say is it would be better to hold loyal miners and value their effort. In the long run it wont matter for the stable miners, and there would be less pool hoppers if they know that their effort wont get lost.

From site:
"Your work is recorded in shifts. When we create a new block you get a share of the income proportional to how much of the work in the last 10 completed shifts is yours."

Why is it good to have ~1h shifts?

Average block finding rate should be ~4h
Calculations:
Diff*2^32/hashrate/time in seconds
1418481395*2^32/420000000000000/3600 = ~4(h)

Now we are having ~20h run to get block and there has been way more than 10 shifts in it - some of our effort will be lost now. Maybe shifts should be 4h or smt like that? Roll Eyes

7 BTC shipped to USA.

-EP

Seems like we have winner in here?
7 BTC (inc shipping), so its about 6 BTC to me
Im ready to ship from 02.jan (thu)
I must investigate shipping to USA, haven't done it before and don't know all the tricks to make it super fast Undecided

Selling KNC Saturn.
Average hashrate ~279 Gh/s, my cheap electric meter is showing ~335W from the wall.

October release.
Location: Europe, Estonia
Same or next day shipping after getting payment.

I prefer to sell to EU region. If needed I can configure miner before shipping so all you have to do is - plug it in and start hashing like madman.  Wink

Tough Questions about the Monarch Card
http://www.butterflylabs.com/monarch/

Q Hey you Jerks, what are you doing announcing 28nm gear while you're still shipping 65nm? I want my Single!

A

65nm products are shipping in volume now after over a year of delays, but they'll be out of production before the first 28nm Monarch cards are through development and ready to be shipped.  If you haven't already received your 65nm product you wont ever get a return on your investment, but you will receive it very soon. It will be useless for mining maybe you can use a single case to drain boiled vegetables, by opening one end. Another good use is to get many of them (they will be $2 soon on ebay) and play BFL style Jenga.  

The ASIC engineering team switched to 28nm shortly after tapeout of the 65nm, when they could have been used to help production of the products we sold a long time ago. Because chip development is traditionally a year long process (we like to make excuses where we can), ASIC engineering teams work far in advance in order to deliver the outdated technology to the market.  Please don't think that production of your singles ever lost a second to 28nm development, because they lost hours, days, weeks and months.  We've put minimal resources into building our supply chain & production capacity so that we can serve our customers, after all once we have your money what do we care?!  Nothing is more important to us than shipping your order after it's obsolete.

Q Will the power & performance really be that good?

A

BFL began making bitcoin mining hardware in 2011 with the announcement of the now famous FPGA 'Single'.  The delivered speed was overestimated to gain sales, but the power consumption was higher than the design simulation indicated something we have a track record of now.  The product was mediocre but to be honest people could have made something similar with a little skill and experience.

So fast forward to our first generation ASIC chip which was an original design.  We delivered exactly the speed promised over a year late, the power consumption was higher than predicted, and we used this to scam people into making a decision.  We held customers to ransom, saying they will all ship in June or July.  We forced people to agree to new terms and conditions then took another 5 months (and counting) to get some orders out.  We really are a company that will tell you it's raining and piss on your back.  That 65nm ASIC chip is now almost worthless as soon it will not be efficient enough to be profitable. It's a chip, that we used to make you guys the Guinea pig for this soon to be obsolete hardware. We are confident that our Monarch will be able to produce 1.7 GH per Joule, an eight-fold increase over our 65nm ASIC products, but take that with a huge pinch of salt, as we made many claims in the past that were not true or never happened.  

In sum, the value of a 2nd generation chip can't be overstated.  It allows us to optimize with great vision and it takes the guesswork out of calculating power and speed in the final silicon design.

The bottom line is that BFL is only interested is profit and does not care if the customer is left in a world of poop!
 

Q Can I transfer my existing order into a 28nm Monarch card ?

A

Yes, but again bear in mind how slow we are, how we will tell you it's almost ready, when actually we know it's way off.  Also there is the risk we will have to defend a law suit or several, so your money may be used for our lawyers.  Heck, we're gonna need 'em.  So just keep this in mind before transferring.


Q Can you host these for me?

A
Yes we can, but again be aware that, there may be long delays.  

Q Why should I place my Pre-Order with Butterfly Labs?

A

That's a good question.

Since 2011, Butterfly Labs has been telling customer "not much longer" so why break the habit of a lifetime?  As we enter the 28nm era, we're the only competitor with a CEO proven guilty in court of fraud.  We have 45 employees, some of which may be facing law suits in the future, a painfully slow production line & fragile supply chain.   Our 28nm competitors don't need to belittle other competition in the way we do.  Most of them have a track record that makes us look incompetent.  Their manufacturing, supply chain and engineering are all back-of-the-napkin ideas, like the Avalon guy that beat us to the ASIC market,  it really shows how useless we really are.  

    Shipped more outdated ASIC's than all competitors combined
    2nd generation (vaporware) ASIC
    4th generation bitcoin processor (We have got worse with each generation)
    Slowest production line
    45 employees most with a lack of customer service

Q Why should I place my Pre-Order with Butterfly Labs?


A

And here's the kicker,  we guarantee you that we will keep making you feel that it is close to shipping but, our track record does not lie, we are lethargic and borderline incompetent.  We will give you a small slice of the truth and after we get your money, there's no getting it back.  

We've been in development for approximately six months.  We're now in the final stage of the process which is wafer start at the foundry.  However, I must stress how we only at the PRE-ORDER stage.  We have NON-PRE-ORDER products if you want order them, but even though they are not PRE-ORDER we are still shipping orders from April this year.  

With that in mind, you will be lucky to get your miner by 2015.

Here are the timeline milestones:

    Tapeout (Initialization of wafer production)  
    Foundry production takes 10 weeks   (our delays take another 30 or so weeks)
    Bumping, Slicing & BGA packaging takes approximately 2 weeks  (but approximately can mean withing +/- 200% or more)
    Initial shipments begin and ramp up to full capacity over the following 3 weeks

Since this is our 2nd generation ASIC chip, we're largely free of risk from the pitfalls normally associated with a new chip design, but we are likeley to find new excuses in the future.  Testing systems, Bumping masks, Substrates & under fill engineering are all carryovers from our proven first ASIC fail, so with that in mind, remember we were only so good last time due to beginners luck.  And remember when we do delay, we will stop offering refunds when the new product is obsolete.  

 We are ButterFly Labs,  and our latin moto is "Mora, praestigiis, quam turpis est!"

Hahaha!
Super good post!! I laughed my ass off.

Is 0,3W per GH even possible? KNC is now talking about 20 nm product with 0,7W / GH

People that are looking for conspiracies can find one everywhere. Bitcoin is conspiracy friendly anyway because we don't know the identity of Satoshi and because of other things that came to light like crypto algorithms being potentially rigged by the nsa.
So yeah - NSA designed SHA256 hash function that BitCoin is using. Strange.. Sure - hash functions might be rigged by them somehow.
Im not expert on cryptographics so i dont know how they could use it against Bitcoin.. Cheesy

That's well known and not strange at all. It's like saying that everything that uses a Sha functions is built by the government  Tongue
Rigged algorithms nevertheless might be a real issue.

I dont know why Satoshi decided to pick SHA256 - it might be problem or might not be Tongue

I dont want to say that USA government is behind of BitCoin - that may be another topic (that Satoshi actually means something about new world order or he/she was government agent and so on..) Tongue
 
All i want to say, that everything that uses SHA functions MIGHT NOT be secure at all. It might be easily breakable by NSA.  Roll Eyes

bitcoin will never see 3$ again its up up and away from here Grin

http://en.wikipedia.org/wiki/Tulip_mania

"As the flowers grew in popularity, professional growers paid higher and higher prices for bulbs with the virus, and prices rose steadily."

"Many individuals grew suddenly rich. A golden bait hung temptingly out before the people, and, one after the other, they rushed to the tulip marts, like flies around a honey-pot. Every one imagined that the passion for tulips would last for ever, and that the wealthy from every part of the world would send to Holland, and pay whatever prices were asked for them"

"People were purchasing bulbs at higher and higher prices, intending to re-sell them for a profit. However, such a scheme could not last unless someone was ultimately willing to pay such high prices and take possession of the bulbs. In February 1637, tulip traders could no longer find new buyers willing to pay increasingly inflated prices for their bulbs. As this realization set in, the demand for tulips collapsed, and prices plummeted—the speculative bubble burst"


So.. sure there are risks and history seems to keeps repeating itself.
Of course i would like to see BTC price going to replace current monetary system - but lets keep our calm Wink

The number of unconfirmed transactions is very high and growing rapidly. I've changed our settings to make bigger blocks and include more free and minimum fee transactions. Hopefully that will help somewhat, but I think we need other pools to do the same.


About that change you did in settings.. Might it be connected with bad luck that pool is having lately?

SHA-2 is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard (FIPS).

I think that there is something fishy going on with BTC. Prices are going up really fast -seems like more speculators are entering to market.
It is only good for bitcoin - price will rise insanely.
But this market is so fragile - i would like to see BTC price after there is some bad news about it. Something that USA is planning to ban btc protocol.. Cheesy
