Topic: Official BITMINE CoinCraft series 28nm ASIC miners thread - page 31. (Read 565240 times)

After all the scam bitmine did to me (late delivery, reduction of the compensation, selling my hardware to others, ...) I finally rejected all hardware from them and asked for refund. They told me I need to wait 30 days to get my money back .. wtf .. no matter what, 49 days are over, still no money back. They even do not respond to any email any more. Really bad, seems like my money is lost. Again (Virtual Mining Corp did the same thing to me)!

for those who care:
order-numers: 3339 & 4645 (payed with bitcoin)

like this

Though I wuss out and put eletrical safety gloves on to throw the switch and press the buttons - I dont trust these cheap chinese contraptions.

Also dont trust them enough to leave them in for a long time - put it in - see watts - take it out.

Now,  a real question. How do you guys easily measure the powerusage of your mining hw?

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.

But this 'newer' product is available for immediate delivery.
http://bitmine.ch/product/coincraft-desk-gen2/

I ordered and payed in January and February.

Middle of June i received the order (picked it up) with 150% compensation, so I got 250% GHs of my original order.

Yes it was akward. But its a very good stable product. There is nothing better on the market right now for immediate delivery. thats the truth itself.

cheers and happy mining.

Try troubleshooting it one module at a time:

If you read about 30 backwards you would notice that nobody has gotten the miner to run at a speed that Bitmine has originally promised with their "up to" declaration they had.
you still can find some better settings than the normal settings where both power and hash is somewhat parallel and reasonable.

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

I've run each module by itself, then combinations of two, then three, and finally have it hashing stable on four modules.

So the result of my troubleshooting is that I have to leave one module unplugged (PCIe cable disconnected).

Hi guys! I am one of those who fall for the promise of a great mining experience with these Coin Craft Desk units. I ordered back in Sept 2013 for the first batch and it came until May 2014. Complete disappointment. Now I'm struggling to get any ROI, but anyway I'm not here to discuss this.

The CCD is already running but my concern is that when I setup the miner to Turbo Mode it doesn't get to the promised Hashing speed using 4 modules of 200GH each. The more intresting thing is that when logging in to the CCD dashboard it says 900GHs+ and when looking at my Bitminter dashboard it reports 600-700+GHs. Less power than when setting the unit in Nominal. I thougth that this was because of the mining pool. I gave a try to BTC Guild and got the same outcome. Less power than what the miner reports in its LCD and dashboard.

Previously I've sent an email to the Bitmine "Support" (sorry for the quotes, but if there are/is any Bitmine member is in this post, you guys always give false expectations and never come out with a solution) and what I've got as answer is that they are "working" on a "new firmware release" which I have never seen or heard of since I bought the unit.

Giorgio and/or whoever else is responsible for this company I'm really disappointment at you guys. You stated that you will not be the next BFL Sh..T  but you are getting there (or are already there). Unexpected delays on product deliveries and refunds  . Changing policies at the last minute to fit your needs  . Poor support and communication skills  .

If anyone in this post is able to make the CCD achieve it's Turbo hashing power and make it recognizable by the mining pool please let me know. Also if the so acclaimed "Firmware Update" is available somewhere in the Internet I would appreciate if you can share it in this post. I tried googling it and all point to Bitmine.ch un-updated website.

Cheers!

PS. This unit will work pretty cool as a high electricity consuming home heater if it don't make any ROI. Can I convert it to a microwave or some kind of convection oven? At least it would heat food or do popcorns. Just a thought.
