Here one more than adds to demand have 4500 euros, keep informed fubly.
Hello everyone,
I necessarily need the following documents from you:
1. Have you paid by wire transfer? If yes, I need the bank statement as a substantiation for the payment.
Have you paid with Bitcoins? I need a screenshot of your payment.
If you paid another way I need something that proves your payment.
2. To submit your resignation I need the documents you sent them such as a fax confirmation, an email or other.
3. I need the demands you sent them to ask for your money. Their email server always sent a confirmation that said that you sent something to them.
4. I need the memorandum. Hand written ones are enough if you called them and wrote down what they said. No witnesses are needed, just the date, time and the member of staff you called.
5. I need an assignment of claim. You can look for a simple assignment online.
You`ll get (if I have 1.-4. from you) a payout that my lawyer will calculate which you can add to your declaration if you think the sum is alright.
You should definitely extend their deadline to 30 days with the threat of getting a lawyer.
Feel free to tell them that you will assign your claim to us if they won´t transfer the money to your bank account.

tomorrow you will have more than 100 000 $ I think. They bought Ferrari but doesn't have money to refund

Please send me some more pm about your interest to sell your claim.
Now we have about 45.000 USD.
How it works, and what rate you get depends on the amount of claims.
First target, reaching 100.000 USD of claims
thx

I would also consider selling my claim.
but it will depend on price and terms.
bitmine ch own me arround 6600USD

I would consider selling my "claim". How can it be done and what price are you willing to pay.
I have an order for about $3400 USD paid Dec 2013 and nothing from Bitmine but bullspit for over one year.
What do you mean my selling my Claim to you???
yes!
I need some assignments of claims, to file a petition in bankruptcy.
My own claim is 11000 USD

- the hashing modules are designed in such a way that IF ONE CHIP FAILS, then THE ENTIRE MODULE FAILS. Whoever knows about electronics, this is their doing: the chips are chained in a SPI bus in such a way that each hashing result is passed backwards through each chip until it reaches the cgminer program. If one chip fails, then the other chips in the chains, after the failed chip, are unable to pass
That explains why module failures aren't graceful... it's an all-or-nothing thing. I have four 1TH/s CoinCraft Desks, and one module has failed on each of them.I switched them off last night. I run them in my house and it's just too hot to run them in Summer. Plus they make a lot of noise.
....
Well.... SPI can be addressed using another SPI bus and a 16-bit SPI port-expander like MCP23S17. This means that 16 individual A1 chips can be addressed individually and the data can be passed on the common bus.
I don't know what speed has this MCP23S17 (around 10MHz?) but a specialised port-expander could be built for this purpose, like they did their custom-made A1.
...
True of course. But complexity of PCB, routing and extra parts in BOM are just not worth it in equipment that will be obsolete in half a year. Well.... SPI can be addressed using another SPI bus and a 16-bit SPI port-expander like MCP23S17. This means that 16 individual A1 chips can be addressed individually and the data can be passed on the common bus.

All this time it worked at normal (nominal) speed with no overclock because the web interface says the warranty will be broken if I enter advanced mode, so I did not play any stupid games. My money are earned with hard work. And now I am really pissed.
Underclock works on my machine. I played with their settings (650mV/800MHz/4000kbps) and it works perfectly. Check my previous posts to see how to modify the internal python program.
Well.... SPI can be addressed using another SPI bus and a 16-bit SPI port-expander like MCP23S17. This means that 16 individual A1 chips can be addressed individually and the data can be passed on the common bus.
4 wires (SCK, SI, SO, RST) for a MCP23S17 addressing 16 A1-chips and another 4 wires (SCK1, SI-1, SO-1, RST-1) to collect the data from those 16 A1-chips.
One chip fails? we get a timeout reading its results and move on to the next one. And the internet is full of procedures from assembly to visual-C, from a simple PIC to x86 and ARM32 architectures, to get such a MCP23S17 up and running. Or the datasheet can be read and the brainzzzz can be squeezed and scorched to write a fully-pure-ASM (assembly language) high-speed software function.
I don't know what speed has this MCP23S17 (around 10MHz?) but a specialised port-expander could be built for this purpose, like they did their custom-made A1.
I design industrial-grade hardware devices for monitoring machines in extremely inflammable areas at petroleum drilling and extraction sites, with tons of arse- and brain-f* papers and documentation approved by high authorities in companies and governments after months of headaches, checks, re-checks, f* tests and arse-f* conclusions on hundreds of megabytes of PDFs and tons of f* papers with my f* signature wrote with my own hand on each of the f* sheets. These equipments must be perfect because people life depends of them, families earn money, they enjoy life, holidays, wife, children, job, careers. Failures and mistakes gets people in hospitals, morgues, tears, families destroyed, me in the f* prison and mein arse-f*ed for decades due to a wrong calculated f* resistor/capacitor/inductance value. I don't play childish electronic games, every night I'm cursing the f* day I decided to get this f* job so believe me I know what I am saying. Their "official" miners were manufactured to fail in the near future. Nobody can believe that smart-arse who invented the A1 chip can be responsable for such a failure in the coincraft miner PCB design and specifications. This failure was intended from the start as their long-term strategy. It may look like bitmine partially kept their promises and terms, but they still sold bitsh*tminers. This skunk-arse-stinks like FRAUD. They are really LUCKY these miners are not life-depending equipments, really-really-lucky they are. Very lucky.
By the way - right after the previous post I overclocked my coincraft desk to these custom parameters: clock-speed 1500MHz, core voltage 930mV, SPI speed 8000 kbps. With 4 working modules left I got 1.4TH/s - around 350....360GH/s per module (I am unable to repair the 5th one). I disassembled each PCB from the sink and I applied that old legendary soviet heat-transfer white paste. 4 pieces - 12 volts, 8 amps ventilators (coolers) from some old-school mainframe server (from the era of open reel-to-reel tape storage), two pushing air inside, two pulling the air out to circulate the atmosfere inside the unit. The noise is un-f*-believable low, wind-only, no buzzing or humming. One such ventilator flies off the f* table if it pushes the air downwards and it lifts itself off the ground if guided through its holes by vertical thick wires. I am lucky that in my country at this time of the year the temperature is around -32 degree celsius (-26F) in my area and the coincraft works inside the hogsty, or henhouse, hen-roost, use google-translate to understand this word. It stays where the chickens used to sleep at night, doors and windows are removed. The temperatures recorded by both sensors are around +44 degree celsius (+111F) with -32C (-26F) ambient temperature. No more power connectors to the modules, the wires are soldered directly on the board. The PSU does not show any problems yet. This is COOL and from me the single A++++ and respect for bitmine. I'm melting ice on 40 x A1 chips. For the rest? arse-f* them. I want to see if the unit survives this night.
The A-1 is f* strong and well designed. But the miner design they chose to get fast money..... that is the job for a trial with judges, lawyers and jury. And bitmine's arse in jail for sh*ing on this wonderful chip design and of course on people's heart and trust.

Since I designed one miner with those chips I can confirm that documentation is terrible. Errors and unknowns...
Regarding SPI, well, SPI in string works that way. Any string design work that way, one chip dies, whole chain i unusable. Without manual rerouting chain will remain dead. Of course is possible to design PCB such way that manual rerouting can be done via simple jumper desolder/solder but with this type of equipment (obsolete in half a year) is simple uneconomical...

That's what I thought too.
These machines are working for 10 months now.
Generally speaking they seem to work fine, especially with no over-clocking,
In this difficulty, they'll be shut down FOR SURE when spring comes.
For a few more months they will continue to be used as heaters,
which bring back a portion of the electricity cost,
useful if someone was going to use electricity for heating anyway.
PS It's a shame that this, so much advertised, under-clocking doesn't seem to work.

Allright
One module crashed, I followed the procedure and I politely wrote an e-mail.
In the mean time I decided to take the matters on my own hands and start to debug the board.
First impressions:
- the hashing modules are designed in such a way that IF ONE CHIP FAILS, then THE ENTIRE MODULE FAILS. Whoever knows about electronics, this is their doing: the chips are chained in a SPI bus in such a way that each hashing result is passed backwards through each chip until it reaches the cgminer program. If one chip fails, then the other chips in the chains, after the failed chip, are unable to pass their results. And of course no commands can be sent to them because the command blocks at the input of the failed chip;
- the heat-transfer silicon paste is of poor quality and it is applied in a hurry. The same chinese-made paste turns into STONE so the heat is no longer transfered properly. This means most of the hashing modules will FAIL. Of course, the hashing modules in their mining-datacenters are properly assembled so they never fail. This means we were all fooled - all of our units will soon fail. You know why? BECAUSE BITMINE WANTS ALL THE HASHING POWER TO BELONG TO THEM AND ONLY THEM, NO OUTSIDERS ALLOWED;
- On each hashing module there is a big aluminium radiator on the backside of the circuit board, which takes whatever heat is transfered via the shit-style silicon heat transfer paste. On the circuit side there are some smaller radiators which are fixed by another shit-style paste. In time this paste turns into stone and no longer holds the radiators. On the datasheet it is specified that 70% of heat is transfered through the big radiator and 30% through the small radiator. Well.... check for yourselves: the smaller radiators are moving and vibrating, they are not attached to the chips;
- the A1 chip datasheet on github is NOT PROFESSIONALLY COMPILED - there are no graphics that shows the curves corresponding to hashing power vs heat, hashing power vs input voltage, heat vs frequency - there is no scientific evidence of a serious design;
- trying to bypass any failed chip results, again, in a non-working module. You cannot repair it, you cannot bypass the bus to pass the i/o data to the other working chips because the chip addressing is no longer valid.
This will f*ck whatever defence they will try to build with their expansive lawyers.
I offered my help to them as a designer, as I have around 20 years of experience in the field. Do you know what they answered me? SILENCE ONLY. NOTHING.
So this was planned from the beginning: sell crap, get a lot of money, in the future when the difficulty raises there will no longer be any "outsiders" to contribute to bitcoin calculations and they will get all the profits.
Anyway if you guys manage to get them in front of justice and you decide you need any professional expertise, please let me know. I will bring my (whatever working left) unit in front of the judges, disassemble it and explain to the court with simple words that this was a planned scam from the beginning.
I waited politely for their answer and I even presented them some of these evidence, as a good-willing customer that is worried about the company that sold me one of their products. No answer received allthough my e-mail was read. It is business day but they are not interested in business.
So I am sorry bitmine, I was polite for more than a year with you, I offered my help for free, I told you about the design flaws in your products but you treated me with your arse and not with your heart. Instead, on this topic the guys discovered that by magic a Ferrari or whatever car the bitmine boss bought with our money.

So, Hi!
What do you think about manually get back our money?
I mean hacking, or other methods, because till we get back our money - that price should be around 0.

Ya lets SPAM this betrayers.
I talked to the cybercrime Division in my Country. They told me i Need to make a official Charge at the Police. Then they can start to investigate.
So PEOPLE take all your e-mails etc. stuff related bitmine go to your next Police Station, make a Charge and then contact your cybercrime Division at home. LETS ROLL THEM TO THE knees
