Topic: Official BITMINE CoinCraft series 28nm ASIC miners thread - page 32. (Read 565301 times)

I ordered a 2Th/s rig late last year, after a lot of delays Bitmine offered me to send me 3 x 1Th/s Coincraft Desks which they did within the 7 days we agreed upon. Two of the modules was faulty, so they sent me 2 replacement modules. They still owed me the price difference and the cost of a replacement powersupply (one of them died after a couple of weeks hashing) as a refund, instead of sending me the funds in euro's or bitcoin they offered to send me 2 modules. As my miners were fully equipped I couldn't really use those... so they sent me a complete 400Gh/s unit instead. So even though they were very busy they were able to send me the replacement parts and a compensation for late delivery.

The way I see it they are doing their best but have underestimated the complexity of both designing, manufacturing and distributing their hardware. Keep in mind this is not Intel, AMD, or some other big electronics company. They have probably paid for a lot of hardware up front, when lots of customers demand a refund it's like a bank run... their is no money, just a lot of hardware.

I have always said you can compare this to the goldrush: the people who get rich are not the people digging for gold, but the people selling the shovels Even though I realized this I find bitcoin so interesting that I wanted to be part of it, as an evangelist what better way to put your money where your mouth is than mining?

This certainly hasn't been one of my best investments, but not one of my worst either. It's no excuse for Bitmine to ship late or not send a refund in time but we need to keep in mind that the whole bitcoin mining industry is still in it's infancy... delays are common, my first miner was from Butterflylabs, needless to say I never made a cent from that investment. (I suspect BFL was/is a scam) Personally I think you should only invest in something as risky as mining when you can stand to lose the money. As far as my little mining operation: with a little bit of luck I'll break even by the end of the year and make a tiny profit. When the miners are using more power than they return I might try my luck with some altcoins... and in a worst case scenario I'll have some power supplies and a couple of RaspberryPi's "for free"

I don't believe Bitmine intentionally shipped/refunded late, from my experience they have done their best to help me but they seem a bit overwhelmed by their own success, their tight schedule and the fact that the refund plan they have in place might have been a bit too optimistic.... especially when large groups of customers demanded a refund this can cause huge cashflow problems.

Don't get me wrong, everyone who asked for a refund should get it as this was part of the agreement with Bitmine. This is just my personal experience / 2 satoshi's... I sincerely hope they are able to refund everyone and professionalize Bitmine.

Yes.

And 1.3watt/gh is outdated too.

HAHA now they are (basically) copying the china A1 "clones" designs. This is too good!

If you have cheap power, it can still be a good buy.

Yes, a great deal!*



* if you're retarded

this is a new desk -> only 4 moduls.....  32 chips... i think the miner runs normal at OC...

This actually looks to be a good deal:

(1TH desk shipped withing 48 hours)

Their cloud hashing plans are also priced quite competitively.

Let´s hope they can generate enough revenue from it to complete all their outstanding refunds.


Does anyone know how much the maximum desk performance is (with overclocking)?

It's not Kerim's fault. He's just working in customer service. He's trying to do his best but in the end he is not decision maker. His boss or creditor's team tells him one thing first (lie) and so he repeats it to the customers and then they change their mind and tell him a different thing. I took me 5 weeks to receive my refund but I finally got it on 22nd May. I kept calling almost every day and Kerim was doing all his best. I felt how much stress he is under because he was constantly forced to mislead the customers.

someone know what to do when the device told you cgminer not connected
i have tried so many things, check the cable, restart so many times. reset it nothing works
i ve also tried to contact bitmine, but there are no reply from them

any help?

thanks in advance

Looks like they have taken four blades,  and overclocked them as high as possible.  The nominal mode is the new "power save" mode, and they are unable to be underclocked. (Which,  as per my understanding,  the old ones never were able to be underclocked, either...)

$1600 for 1TH. $1.60 per hash.  At around 1.3 watts per hash.  Compare this to, say, Asicminer devices,  which pull about 1.1 watt per hash and cost .80-$1 per hash.  And by all accounts Friedcat is selling those chips at near cost,  as he considers them outdated compared to Antminers current offering,  let alone Bitfury and SP's soon to be released chips.

These things will put off a lot of heat. That case isn't very good at defusing it.  I wonder if they have given adequate cooling for it?  I'm guessing not.

seems like Bitmine has released their "new" 2nd generation miner
http://bitmine.ch/product/coincraft-desk-gen2/

As far as I know they didn't say they built that data-center themselves. It's most likely a facility that already exist (not like Reykjavik isn't already full of them: http://www.datacentermap.com/iceland/reykjavik/), so they just bring their stuff (desks/rigs) there and let the facility manage the maintenance. Why wasting money when you already have all the necessary installations?

Ofc I'm just speculating. Would be too simple if they were clearly communicating about it.

As far as I have seen in the posts here, bitmine.ch builds a mining datacenter on iceland with our money.

They don't have the money. They converted it to material, so ofc they can't refund us with money, only the material. Or they can sell the material then give us the money...but sell it to who? Only to us, nobody else would buy it anyway. Endless game.

I'm not saying it is ok, fair, or normal, but that's just the way things are. They can't give us something they don't have. To me the choice is clear. Better get some material than nothing. Better get it quick before they completely go bankrupt and/or get sued to death so all their shares are locked.

+1 
For God sake , now it is almost half of the July, how much we must wait for the refund ?
Bitmine AG do you really care about your customers ?
Bitmine AG, are you a serious company or you just stole our money ?

This. Just refund my damn money like you promised. I did not agree to be an investor in your data center or whatever the fuck you're doing.

They wrote everybody to be refunded in September and October. This is bullshit again. They will say in autumn that you have to wait again (they will cry a river also and bla bla bla) or you can change to the bought price for the new machines. BFL did the same scam last year for their clients.

Dear Bitmine.ch!

No client asked for your investment (warehouse)! Nobody cares of this! You hold our money for your project which you break the law in many points.

We didnt buy in your warehouse project we paid for the machines which you havent even shipped in time nor send back the refunds according to the contract what you agreed as well.

How many more rules do you want to break?

Who do you expect to buy your shit in the future? Why do you think if you will establish a new company in the future to try to scam the ppl again in another name nobody will check its background?

and why do you think that your current company is in secure...?

And on top, Kerim denies me to refund of the shipping costs due to the fact that I drove down to swirzerland and picked the miner up myself. He thinks I'm to greedy....wtf?

But procuratorial is already informed.

This company is a house of bullshit. Do not buy anything from them, they just lie, scam and fu** your a****s...

Giorgio already used every excuse from his "book of lies". Currently he is waiting for the second edition...than he will come back with answers...

every day the boss is online:

but he say -> nothing...

Bitmine is one of the WORST crypto "hardware" companies ever. On the same level as BFL. Scammers, whether deliberate or forced into it by bad business planning etc, they have stolen my money even though I filed for a refund APRIL 1ST! No refund wire ever received.

Blowing smoke up my ass via phone support, "You have been submitted to the refund pile, blah blah blah...." Just completely lying to my face, "your refund will be in 2 weeks" then 2 weeks later "Just 2 more weeks" blah blah, just complete bullshit. Karim, yes I'm calling you and your overlords out....telling you to lie to customer's faces. Why lie when you could just be frank and level with me? Then give ZERO updates, basically just leave people hanging in the dark with no answers whatsoever. If you knew about blowback, you'd know that lying and hiding in the shadows just antagonizes and pisses off the customer more.

You DO NOT treat customers this way unless you have absolutely ZERO concern that your pissed off customer will come to this forum or where ever and tell the facts, painting them in a aptly deserved bad light. This is not the way you run a business and retain customers, much less get new ones. Scammers, liars and thieves period.
