That's pretty sick... Unfortunately I don't have a business to run my machine at, and anytime I've got more than 12 cards running, my AC & vacuum won't play nicely together. I'm almost afraid I'll start a fire one of these days...

Anyone heard anything back from cointerra in regards to refunds?

I've sent an additional 3 emails since my last post, and all have fallen on deaf ears... This is highly frustrating.

I agree with several others here. The refund delay is unacceptable and highly unprofessional! The email correspondence is also highly lacking. I would avoid making purchases from this company until they get their stuff straightened out. If it doesn't work immediately out of the box, you'll have nothing and no way to fix it for weeks.

Sorry, are you 5 days over the 4 weeks waiting?

i am only waiting for 2 weeks but you guys freaking is slowly starting to concern me.



I've seen a lot of people waiting for the 4 week mark, but I was never told 4 weeks. In an email, a John said that my refund was going to be processed by the end of "next" week. Here we are, 2 weeks after "next" week, and zero communication! I'd honestly be very worried if I were you. I felt pretty good with the communication from Cointerra until they said "your refund is coming" and then started to ignore all my emails.

I wouldn't call it a scam, but it is a slap in the face to have very quick turn around times for my first few emails, then being told I'd get my refund processed in a week, then absolutely no communication after that. I bet I could email them about a question and get a response within a day, but if I ask anything about my refund, nothing but silence. It really sucks beccause they don't have bad products. Just poor communication skills when it's something they don't want to hear.

Re: Cointerra REFUNDED— People Asking for refunds.. NEWS UPDATE!!!
by
witherworth
on 10/05/2014, 05:43:01 UTC
So, I saw a couple of these kinds of messages and was really hoping that Cointerra was just having a bad week, overwhelmed with this or that and was getting back on the ball. Unfortunately, that wasn't quite the case.

I sent them a refund request on 20 March - request number 15712. After a few emails back and forth (boy they were pretty good at responding to requests in a somewhat timely manner (1-2 days tops)), I finally settled on getting a check refund (instead of BTC like I would have preferred).

Several emails later I finally got a reply on April 16th stating:
"John (CoinTerra)
Apr 16 11:27

*****,

I have marked your refund to go out as a check. I will attempt to get it processed this week, estimated delivery by the end of next week.

Thank you. Please contact us again if we can be of further assistance.

~ CoinTerra Support"


I was really excited to be getting such great customer service, considering there were so many posts on here about issues. I was glad to see they had fixed stuff up. Unfortunately, thats the last email I've received from them, depsite having pinged them several times to ask for updates or if there were issues and I even asked for a "hey, we're busy, sorry" email, but that seemed to have no effect. I'm not entirely sure what I'm supposed to do at this point. I've run out of options that I can think of. Any ideas?

I'll have a more detailed update next week for Teraminers, just wanted to leave a little something here.





It's a 5Gh/s beast at 30w humming away on my desk as I type this.

I'm glad to start seeing BFL deliver equipment and am looking forward to moar!

Thats a shit ton of HW errors for number of accepted shares. I'd be interested to see the ratio after several hours of mining. Care to share an updated screen shot?

Re: Looking for an ASIC solution
by
witherworth
on 28/04/2013, 01:03:01 UTC
I'm looking for an ASIC solution that meets these requirements:
1.Must be available or have a short queue (not like BFL who quoted me 3 months from US to UK)
2.Must have actual existing products (not pre-order)
3.Must be able to buy it or use it today (or soon)
4.Must be reasonably priced (budgets can either be under $300 or no more than €1200 for the products in question-I'll sort out budgeting later once solutions are found)
5.Must be able to deliver promised returns (hashpower and BTC mined daily)
6.Must be plug and play,no setup/DIY kits involved.Anything that requires anything more than plug,play,install supplied software (must be GUI) and mine will fail this criteria.
7.Power consumption must be reasonable for the hash power provided for each respective type of ASIC.

I'm looking for someone who can post examples of ASICs that meet my requirements.Any help would be appreciated.Thanks Smiley

There are none that meet your criteria.


Also
BTC mined daily
Will change as difficulty goes up or down, which is why you should ignore and run away from anyone who is trying to quote you specs based on this value. It looks all fine and dandy when someone offers to sell you a machine making 1 BTC per day, only for you to realize that next month you'll only be making 0.5 BTC, which may not be quite as good an investment as you thought. Having a few of those Avalons or BFLs right now would net you hundreds of thousands of USD based on a year of mining. You could make your first million in just over a year... Except that difficulty changes and you're no longer makings 1 BTC a day (47k a year), you're makings 0.25 (<12k a year) for your 20k investment.

Re: The new design of BFL Single

BFL's 65nm chips perform nearly as bad as 110nm chips.


Wait, what? I thought, chip for chip, BFL's chips seriously outperform the Avalon ones. Hence why Avalon uses 108 or something chips to achieve 60GH/s, while BFL only uses (im assuming) 16. And while they did seriously miss their power specs, the point is still true that they're more energy efficient per GH/s. I don't run with the "well, everything is alright" crew, as it clearly is not, but at the same time, anyone expecting BFL to ship on time is an idiot, and anyone expecting BFL to be even reasonably close with their power estimates is also incredibly stupid. From the get-go, I knew they would be delayed at a minimum of 4-5 months. So I took that into account. I also knew that they'd miss their power target significantly (not nearly as significantly as they did, but I still knew they'd miss it). I don't support the "BFL are all assholes and fuck everything up" nor the "BFL will make everything alright". I stick to facts. Fact is they've screwed up a lot of things, but do appear to be shipping out now. The quoted section is nowhere near fact. You can say that ordering a batch 1 Avalon is a lot better than a first day BFL, sure (citing the fact that what those customers have now earned will last them thousands of years of electricity costs based on the fact that Avalon uses more electricity than a BFL for same hash power - they're already and forever will be ahead). But based on 2 actual products that exist and have been shown to exist by serveral customers with them in hand, you can't start coming up with crap to troll BFL customers with (despite how entertaining it is from time to time).

Re: BFL Shipps...no for realz... no really

Nice to see them screw over Single and minirig customers.

Exactly my sentiment.

If you are a premium customer, i.e. sent them a wire transfer for 29.5 grand or whatever 5-figure or 6-figure amount, you would expect to get premium treatment and don't deserve to be kicked to the end of the line.

I see no reason why someone should get special treatment for placing a large order in January and them expect to receive their order before someone who ordered last summer. That's just stupid. Personally, as long as they're delivering only a few jalapeños (no more than 1-2 months ahead of when they start shipping singles, etc) it's not an issue. Sure, it'd be a little wrong for me to place an order for a jalapeño today and get it before the first singles are out, but I doubt that'll be the case. Loosen up your panties, they've only just started shipping, and many of us have significant amounts of money in the line as well.

Re: Combo Bitcoin/Litecoin ASIC Miners have arrived.....
by

on 24/04/2013, 11:41:01 UTC

Well,  at least according to this guys auction:  http://www.ebay.com/itm/BITFORCE-BUTTERFLY-LABS-JALAPENO-5-GH-s-Hashrate-BITCOIN-LITECOIN-ASIC-MINER-/330909603662?pt=LH_DefaultDomain_0&hash=item4d0bbfd74e

He has 4 auctions in all with the same title.   Perhaps a quick fraudulent item report to ebay is called for.   Hopefully none of his bidders are as stupid as he is.

 Roll Eyes

It's incredible to see how people is bidding hard to buy a late preorder (January 2013). This is insanity. The one left holding the Jalapeno preorder will be screwed.

Not really since they're only shipping Jalapenoes right now so the January 2013 order might actually arrive sooner then expected. The bigger units are all being re-designed and hence delayed.

Come on, that order will arrive very late this year, and it won't get a ROI even at the original price.

I'm amazed about how people can be optimistic with a company that fucked over for 8+ months.

At what difficulty/network hashrate does the jalapeño become unprofitable? Sure, it may take months upon months, but all ASICs will still be making profits for at least a full year or two. From some quick numbers I saw, it costs $0.10 in electricity, and makes $30.00 in return per day. At what difficulty would you only make $0.10 a day? I think that number is further than closer.

Re: Avalon batch 3 is definitely not shipping on time...
by
witherworth
on 24/04/2013, 03:19:37 UTC
Given the current delays, I'm predicting the median ship time for batch 3 to be May 22.

Won't that suck if BFL starts shipping out regularly within the next month and kills all batch 3 owners? That's making a big assumption that BFL will actually deliver in volume though.

Re: BFL 5 GH/s Miner Demo

on 20/04/2013, 13:45:21 UTC
You can't compare the wattage on a BFL with an Avalon. An Avalon is a self-contained mining device. Add in the wattage for the laptop and the BFL is less efficient than an Avalon! ROFLMAO.


Except it's not. When you add in even 100w for a laptop, then plug in 10 BFL singles, suddenly that laptop only uses an extra 10w per single. There's no point to have 10 different hard drives, 10 wifi modules, etc. all of that can be taken care of with 1 mini computer (~$150 for a new one, running at ~50w with either windows or Linux).

Also, of you've only got 1 unit, run it off a RPi, and that only consumes, what, 10w or something rediculus? You could probably find a way to mount the Pi inside the jalapeño, and cut a hole out the back for Ethernet & additional power cord. Would certainly be an interesting project.

Anyone know what the warranty was for the FPGA single? I emailed them about mine on Tuesday this week, the power supply died. Haven't received any helpful information at all in the forums either. Plus finding out I can't do an upgrade any more makes it even more of a facepalm for me. I received it on November 2nd 2012 I believe... warranty has to be good still right?  Huh
I thought they were claiming lifetime warranties, but only for tr life of their product, which they've had replaced for the past 9 months now.

What's this about not being able to do trade ins? I though they've extended that offer for a while now.

Just watched the vid... something seems fishy that all of a sudden they have a bunch of workers, when the reddit guy who did an unaccompanied tour didn't report many people actually working.

Guys, guys, guys!  They were obviously off doing a team building exercise!  It takes a lot of coordination to descend upon anything like a swarm of locusts and not get in each others' way.  I hope they release a video of that, by the way.  A swarm of 22 locusts...  Can you imagine it??!?

Ah, makes perfect sense!
