Final update: after asking bitpay to (again) lean on all4btc, they finally coughed up the balance. No e-mail, no apology, no excuses -- nothing. It took nearly 2 months for them to refund me money, and they never even explained why they were unable to fulfill my order. Amateurs.

Update: I contacted BitPay after being ignored or brushed off, or whatever you want to call it. They offered to reach out through their compliance department, and this morning there was a refund waiting in my wallet. No wait, a partial refund. They kept 0.0693 BTC, about $69 USD at today's exchange rate. Unfuckingbelievable. I'm glad some people are having success with this company, but based on the abysmal level of service I've received from all4btc, I cannot recommend them to anyone. STAY AWAY. There are lots of other competitors, and they can't ALL be this bad.

After more than 30 days, I still have not received my item. The last correspondence I got was two weeks ago and gave no explanation, just:

>Hallo,
>
>it will be processed tomorrow again. Or we will refund you.
>
>regards

They have not responded to my e-mails and have not issued a refund. I've contacted BitPay also.

DO NOT ORDER FROM THESE GUYS.

OK, they're not responding via e-mail, maybe this will get some visibility.

I paid for an item on all4btc thursday night and paid right away. The payment went through, but it still hasn't been fulfilled. The service fee on my item is around $150 US (it's a BTC3 item). It's been three days. You need to have better response time. Not cool.

They finally responded four days later, asking for the invoice, and after another day, claimed that:

we got your order adn tried it to order directly but it was not possible, because our paypal account did not allow the payment (sometimes this happens...)
We will try it again. Your payment arrived and is fixed in euro, so donīt worry about the falling exchange rate Smiley

It has now been a week. I've messaged them again, with no response for three days. Not professional, guys.

It has now been almost two weeks, and they have not responded again. I've sent them several emails, including one with an amazon link for the same product. At this point I'm pretty sure I've been scammed out of BTC3.

BKKCoins is OK! He was in a motorcycle accident and is lucky to be alive: https://bitcointalk.org/index.php?topic=190731.msg3649002#msg3649002

As for all of you clamouring for Steamboat's blood: give it a rest, already. Did you not read the GIANT BOLD DISCLAIMER warning prospective buyers that this project carries a high level of risk and has many factors outside of Steamboat's control?

Hi Chris, I'm glad you're OK. Thanks for all the hard work you put into the Klondike project and thanks for making it open-source so it could continue while you were recovering.

Did you ever get that floor put in? :-)
10  Bitcoin / Hardware / Re: A3256 based Klondike 2? on: November 17, 2013, 07:38:30 PM
As one of the many people here who have paid for assembly (and test) but who got a refund on ASICs I can’t help but think about revising the Klondike design to use the new ASICs.

...

What do people think?

A question: I’ve been away from this thread for a while, what is the current state of the Klondike design? I know I2C chaining and USB Bootloading are not yet supported, but is it working with all 16 ASICs? Where is the archive for the most recent, up-to-date version of the design?

I would consider it if Avalon gave Steamboat (at least) a 25% discount. Otherwise they're overpriced.

Today's news from Avalon:

Quote
Avalon turns One years old
What a roller coaster ride it has been
We went from the last to enter the ASIC mining market crowd-funded by the community to the first to shipping a consumer product in little over 4 month. On this journey, many mistakes were made, tons of things were learned and we will continue to grow as one of the groups to keep mining decentralized and support the DIY community. Those are our goals.

In the up coming week we will doing a clearance sale on the refunded chips as well as some mining units and modules to close generation one and move on to a pre-sale-less generation two of the Avalon Project.

Stay tuned as many more exciting news will be announced in the coming week.

Everyone should request refunds at this point.
12  Bitcoin / Hardware / Re: Liquid Synergy Designs Inc. -ASIC mining hardware on: September 10, 2013, 02:55:22 AM
We would have to see some GH/watt numbers, BUT the competition has 'about to ship' complete* systems that are 28nm.  They claim 400GH@850watts - also the kicker ~ under $5k USD  

IMO 55nm is dead before it ships.

We're still pretty far from watts/GH/s being a deciding factor. I'm more interested in how much faster Avalon's gen 2 actually is. If it's on par with other designs, I'd expect around 1GH/s per chip. That's about triple the current generation, and actually makes ROI possible.

Anyway, I requested a refund for my order (>4000 chips). If everyone does the same, it gives Steamboat some bargaining power. 10,000*6 is a lot of chips...
13  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 10, 2013, 02:25:40 AM
About the ROI, it really is gone now, but you have to take into account, that BTC price will likely go up, so even if you lose now, you can gain later. Especially if you've already made an investment in the HW, chips etc.

An investment that doesn't earn back its principal is called a loss.

And about changing the HW for next gen Avalon chips (or any other chips), who is going to make this? Bkk seems to be gone (probably get sick of all the events regarding chips delivery, companies taking advantage of opensource project and giving nothing back) and there seems to be noone (even in the group of those companies, which started their business on this) who is able to make this change.

That's a great question! I don't have the answer, but I'd love to get some discussion going and find out.
14  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 09, 2013, 02:31:49 PM
I don't think everyone needs to.abandon.  For the sake of community development. I'd say we finish the project.  If a handful exist  that's okay. I understand people are MIA as well as nerve racked.  That is why I believe wr need fresh hands and eyes on this project.  

Absolutely! I'm not advocating we abandon the project. But there's no point in continuing the design using first-generation Avalon chips. They are obsolete. At this point, with an assembled board in hand, if you mine forever, you will not make back the cost of the miner. However, we can retarget for a different chip and, at the very least, break even.
15  Bitcoin / Hardware / Re: Klondike - 16 chip ASIC Open Source Board - Preliminary on: September 09, 2013, 02:04:13 PM
As the days pass without shipped chips, it's becoming clear that projects using Avalon's offering will not see a profit, let alone ROI. Many of us have sunk money into board and assembly costs. At this point, there appear to be three options:

1. carry on development and testing, hope Avalon ships chips, keep fingers crossed that difficulty stays low enough to break even
2. abandon the project, demand mass refunds from Bitsyncom, and all take individual losses
3. sue sue sue sue sue sue sue
4. retarget the Klondikes for a more powerful chip

#1 is the equivalent of investing in CPU mining during the GPU revolution. We're paying for fancy space heaters.

I've invested enough that #2 is not an option for me.

Anyone crying "lawsuit" has no experience with the legal system. We entered into this venture knowing there was substantial risk. Tough titties people, throwing money at lawyers will not extract blood from a stone.

That leaves retargeting for another chip. I think this is possible. Functionally, chips do the same thing -- iterate over a range of nonces, computing a hash. The board design will definitely have to change, but I suspect the BOM will not change drastically. At the very least, the expensive parts (PIC, buck regs) will almost certainly not change. Also, there is now an actual market for chips, with different suppliers competing on price and features. We're in a pretty good position to negotiate bulk purchases.

Thoughts?
16  Bitcoin / Hardware / Re: Liquid Synergy Designs Inc. -ASIC mining hardware on: September 09, 2013, 01:49:31 PM
OK, here's how I see things:
1. We can refund 95% of the chip cost.
2. Steamboat has already purchased materials and entered into agreements to produce boards, leased and begun work on a hosting center, paid for a large number of custom heat-sinks, and probably purchased lots of other equipment.
3. Many other people are in the same situation, including BKKCoins, who has personally invested a great deal of time and money into producing the K16 and K1 boards.

The chip cost can be refunded, because that comes from Yifu. The other costs are not reversible.

Our options at this point are:
1. roll up the whole thing and individually take a loss
2. enter into costly and ultimately fruitless litigation
3. retarget the K16 board for another mining chip

I'm not in favour of giving up. I've personally invested in 128 K16 boards, paid from previous mining income. I'm sure lots of others would prefer to (at the very least) break even on this venture.

Litigation is only worthwhile when you're up against an entity with lots of money. Otherwise, only the lawyers benefit. Besides, the terms of the purchase agreement were crystal clear: this was a risky venture with many unknowns. This is not Steamboat's fault. This probably isn't even Yifu's fault. We don't know what happened.

That leaves retargeting for another chip. Most of the BOM probably won't change, and the most expensive parts (the PIC, the regs) almost certainly won't change. If we collectively get refunded for all batches, we'll be in a good position to negotiate for bulk purchase from a chip producer that is actually shipping product. At least one other group has retargeted to Bitfury's offering. I think we should take a more wait-and-see approach and not make the same mistake by targeting a chip that isn't shipping. We're not going to make an easy buck at this point, so we might as well be rational about how we're going to proceed.

Hi Steamboat, could you tell us how BkkCoins will be compensated? If that's under NDA, then I'd like to hear from both you and steamboat that you are happy with the deal.
18  Bitcoin / Hardware / Re: Liquid Synergy Designs Inc. -ASIC mining hardware on: July 16, 2013, 03:27:32 AM
Hi, does anyone know a good (cheap) source of PCI-e power splitters, SATA to PCI-e, and 4-pin molex to PCI-e cables in bulk amounts? I'll need something around 40 PCI-e splitters, 48 SATA-to-PCI-e and 24 4-pin-to-PCI-e. Also, I'm interested in any good prices anyone's found for 550W 80+ gold PSUs.

thanks!

I'm not a big fan of Kicad but the main reason I used it was so that anyone could edit and work with the files without having to buy a license of any sort.  So I'm not really looking for a commercial version of Eagle. You have to remember that where I live I could have easily picked up Altium or Eagle for only a few $. Using Kicad was more a philosophical issue. Despite the troubles I had on the way I'm actually kind of impressed that it actually does work. I would change a bunch of things if I had the time and energy to contribute or fork the project - but I don't for now.

If there are specific Kicad bugs that slow you down, perhaps donations could go to bounties to those who get patches accepted that fix those bugs? That is after all one of the nice things about open source projects.

Why do they purchase from this if others are selling with lower order number and for fewer BTC?

I can't speak for everyone, but having completed boards in my hands a few days after chip delivery is a pretty good reason.
