I Ordered two miners from bitmine and the first order was on November 18, 2013 (2THs Miner January batch #2), still have not received access to the miner that was supposed to be housed. (I am now asking for a refund on this in June. Still no response two months later but they brought online cloud mining on their website, so I e-mailed them again about possibly changing my order instead of a refund to make up for lost profit and still no reply but i best just get a refund with the Consumer Protection Plan) This would be 9 months and it was supposed to be delivered
I ordered in November 20, 2013 (400Ghs Miner January 3rd week batch #2) and one miner was brought online May 14th, 2014 housed but has been offline since the beginning of August and I cannot get a hold of them. (This unit was supposed to be under the Consumer Protection Plan but I did not even receive the extra hashing power)

I sent them money for my RMA and all has gone silent on Bitmine's side since...
There is evidence that BITMINE is a SCAM company

My 1 Th/s CoinCraft Desk is dying slowly, only 2 of 5 modules work now stably. Every month one module stops hashing.
After restart cgminer sees more modules (3, 4 or 5), but after some time (seconds, minutes, sometimes hours) remaining modules stop working or became invisible.
Changing voltage or clock speed does not help.
Could it be problem with backplane?
From cgminer log (only 4 modules visible, module 3 stops working after 1 hardware error):

For some reason one of my modules is getting a lot of HW errors and outputs 190gh/s:
This is running on normal settings. If I go to turbo moderate, the first two modules have 8% HW errors, the third stays under 1%.
Any ideas?

Hi people.. I have overclocked about 280 ~ gh / s each module, obtaining 1.4+ th / s @ 1460w~ with low temps.. In the next few days will give more details.. I'm also working on a new -unofficial- firmware.

I did some digging. At least there now seems to exist a company called IceMine. This dude is the CEO:
https://www.linkedin.com/pub/gu%C3%B0mundur-ingi-hauksson/24/90b/b07
They have registered the domain icell.is:
http://whois.domaintools.com/icell.is
There's familiar name there: Andreas Fink. He's the guy behind DataCell, which seems to be a legit mining host in Iceland:
https://twitter.com/datacellcom
So the Bitmine story about the datacenter seems to check out. But that obviously doesn't prove that they are actually hosting any Bitmine hardware there.

Only couple days of August remaining, we have escaped from the "bear trap" of this summer.
The price of BTC will be $500+ from now. So there will be no excuse to shut down the datacenter and to not resume the refunds ASAP.

Well again the value of BTC is below $500...
And this they can use for excuse to "shut down" the datacentre

There are only speculators who shake weak hands to grab more Bitcoins.
If you have some cash, better buy now. The price will raise soon.
Anyway, this is no excuse for Bitmine.ch to maintain "silencio stampa".
I really don't know why they are not confirming if the operation on Iceland is in progress.
We made jokes with polar bears and volcanoes, but Bitmine.ch own us an explanation. If I understand well, from this datacenter Bitmine.ch will mine for Bitcoins and will pay the refunds, right ? ( http://bitmine.ch/present-future-bitmine/ )

Hello folks !
There is anybody who accepted the cloud mining contract amongst you ?
I ask this because I want to know if this person received any payment from the mining contract yet. For example I own a Hashlet from GAW and I receive payment daily !
There are 15 days passed since the cloud-mining operations shall suppose to start in Iceland..
@Dino50 cheer up man ! There is something on this world called KARMA, and believe me you don't want to be hit by the KARMA boomerang

Hello, today my PCB board has burned .. so i ended up with something like that (see below). I have filed a support request with Bitmine already, as my CoinCraft Desk is still under warranty, so far no reply. I read on this forum some of you people have got a replacement from Bitmine.ch, is this true?
P.S. the funny thing is that i was not over-clocking or anything, just moved the miner to the other shelf slot and boom here you go, out of my 800 GHz only 200Ghz are left.. so bad..

I had to call them to get the warranty process going. Emails didn't work for me either...
You have to pay them up front for shipping...
They have a RMA procedure document, which is not on the website...
First Page of RMA document:

They wont refund anybody Im getting more and more sure about that. They only want to win time till the end of the company in a legal way. They will tell a new story in October why they cannot pay again...or you can flip your money to this or that offer you cannot refuse...
This sadly does look like the most probable outcome.Before the fifteenth they were actively responding to my emails about how to trade the refund to mining contracts. After that, nothing. Back to completely ignoring all emails.

Now they sell virtual service which technically means they can more easily suck your paid money and even if you run to your lawyer you can f**k your virtual contract for virtual service for virtual money. The court will laugh at that and you will lose around 350 CHF/ hr paying your lawyer + accomodation if you are a foreigner. Very good money for them but not for me, thanks! The funny thing Im not believing the warehouse thing at all so they have more fun way to steal your money.
And btw who has proof that the data center is existing? I mean not the building then the machines in that. Many of those clients have already lost btc since 15th of August.
3 M USD investment... oh yeah...show me!
Who believes in a company whos every statement so far has been lead to zero realization or loss for the client??
They are very quiet from the beginning of the summer when "cash-flow" problems started and I tell you it is always a fishy thing if you had an agreement with somebody and then the other party is in quiet for months. No notification email no call about the situation. You guys can go on their webpage and see the "news" which means you can go after your order if you want. Who cares? Do they?
One could expect for 5-10-20 k usd or more orders that the company whom the person bought of will be informed by phone or by email about the situation and not the client should search for it. Thats why it is a scam company and there wont be refunds. No money guys! We can talk about it for pages but they wont refund anybody as a conclusion of the above facts!

Already 2 weeks passed, and according to the Bitmine.ch they started to mine on their facility located on Iceland, right ?
I think Bitmine.ch gained some BTC , so here is my question: the refunds are resumed ?

Dont think so..
Dear Mr. xxx,
as you may already be aware we are facing some difficulties to process all the refund requests we have received. With this e-mail we would like, first of all, to apologise for the delays you are facing and to thank you for the patience so far.
Given your position in the refunds processing queue and our cash-flow projections, your refund is expected to be processed about on the first half of October, 2014.
We understand this may be a long time to wait for, as such we would like to give you some alternative options that may be available in shorter time:
1) We may restore your order and send it to you with 100% more hashing power than the original order was. That is, if you ordered 1TH/s, you would get 2TH/s. Shipping would usually take place same day or day after we received confirmation from you, anyway not more than 5-7 days.
2) You may convert the amount we owe you (including the 10% penalty) into hosted mining contracts, which will be available from August 15th. More information is available at http://bitmine.ch/hosted-mining-plans-now-available-starting-1gh/
Let us know if you are interested in exploring either of the alternative options, otherwise we kindly ask you to bear some more patience until your refund is processed.
Best regards,
Bitmine AG, Bitmine.ch
AND
Dear Mr. xxx,
hosted mining service started last friday as planned but it will take some days before all mining units are being brought to our datacentre. In the following days you will receive a coupon with the amount owed to you which will allow you to purchase any mining plan you are insterested into. We thank you for your patience until access to your hashing power has been granted.
Best regards,
Bitmine AG, Bitmine.ch
The last email is 6 days old.
To me they said some while ago that my refund is scheduled till first half of September.
That if the datacenter operation is started according to schedule and if BTC value stays over $500
The datacenter has started according to schedule but I wonder about the BTC value... It was below $500 for some days...
Personally I think that they are going to explain new delays in refunds with that BTC value was below $500 for awhile and that they have had to shut down their datacenter due to the possibility of a volcano eruption on Iceland

as you may already be aware we are facing some difficulties to process all the refund requests we have received. With this e-mail we would like, first of all, to apologise for the delays you are facing and to thank you for the patience so far.
Given your position in the refunds processing queue and our cash-flow projections, your refund is expected to be processed about on the first half of October, 2014.
We understand this may be a long time to wait for, as such we would like to give you some alternative options that may be available in shorter time:
1) We may restore your order and send it to you with 100% more hashing power than the original order was. That is, if you ordered 1TH/s, you would get 2TH/s. Shipping would usually take place same day or day after we received confirmation from you, anyway not more than 5-7 days.
2) You may convert the amount we owe you (including the 10% penalty) into hosted mining contracts, which will be available from August 15th. More information is available at http://bitmine.ch/hosted-mining-plans-now-available-starting-1gh/
Let us know if you are interested in exploring either of the alternative options, otherwise we kindly ask you to bear some more patience until your refund is processed.
Best regards,
Bitmine AG, Bitmine.ch
AND
Dear Mr. xxx,
hosted mining service started last friday as planned but it will take some days before all mining units are being brought to our datacentre. In the following days you will receive a coupon with the amount owed to you which will allow you to purchase any mining plan you are insterested into. We thank you for your patience until access to your hashing power has been granted.
Best regards,
Bitmine AG, Bitmine.ch
The last email is 6 days old.
Already 2 weeks passed, and according to the Bitmine.ch they started to mine on their facility located on Iceland, right ?
I think Bitmine.ch gained some BTC , so here is my question: the refunds are resumed ?
