Topic: 1 TH/S dragon miner. Has anyone tried it more than 24 hours? - page 2. (Read 8040 times)

Can someone give me run down how to setup 1T dragon miner and any one that interested out there. I just had hell of time getting bit burners running. Is the Rasp Pi with cgminer on the dragon miner as easy as the Antminer or BFL interface where you can connect right away or is there a lot of coding going on? Thanks

Of course its belief, you are choosing to believe Giorgio's story over Innosilicon's. Until there is a legal ruling all you have is guesswork and belief. If you stack Bitmine and their managements credibility up against Innosilicon's it makes even less sense.

Mine has been hashing steadily at 1 TH/s. No issues so far.

Belief is irrelevant. If people contracted with a firm to produce chips, paid for development and design, then that firm does not have the right to give away/sell/whatever the resulting IP to anyone they wish. Now, I do not know the finer details of Chinese law or the appropriate terms in the agreement for these chips, however piracy of intellectual property is wrong.

You can consider it to be a moral, spiritual, what have you issue, but it is still wrong.

As for "pre sales" and the like, that is a completely separate and independent discussion from piracy. I have no interest in discussing that or confabulating the issues.

That's not what I am saying at all. What did I say that?

I'm sure the developer of the chips is making plenty of money in China.

The reseller of the chips in Switzerland already made their money fleecing their pre order customers and charging double price for the chips they are reselling to this parties.

All it is is one mans word against another. I'm just wondering why you would choose to believe the guy who is ripping everyone of and not delivering because he can't design a pcb to save his life, or the Chinese manufacturers who have been building, mining & shipping working miners since January.

Strange. Are you saying that chip development should be free or be considered to have zero value because... well the chips are right there now?

Odd.

You sir, are an idiot. And you are butthurt because now your miners are overpriced.

I can understand you feeling ripped off because you paid so much to a reseller of chinese chips (Bitmain) but to go around spreading falsehoods just so you can try and sell your, now, overpriced miners is idiotic.

The 1TH 1kW 'Dragon' miners use a web interface on a Rasp Pi.  They run a custom version of cgminer, and use the API functions to refresh the web interface.

We've had a unit run for well over a week with no performance degradation and no heat issues.

Have a care when purchasing, but they are real miners that work well.

I am wondering does the 1t dragon work on the same perimeters as the bitmain antminers? How is the login and the use of rasp pi.

What a waste of money

I agree.  The 1 TH/S should not be anymore more 2500$. All the ASIC manufacturer out there are over charging. I hate to say this but coin craft should of never manufacture A1 Chips in China in order to save on cost. While charging its customers 5 GRAND. It shot its self in the foot. Coincraft also took the risk that manufacturing in China would lead to counterfeiting of there chips. Although coin craft probably got the chips for dirt cheap. ntekcomputers, I don't believe coin craft is really the victim. Its us who mine BTC.


I have no tolerance for counterfeiting. I want to be clear on that. Although for bitmine to take so long to produce a working machine when Diff is going up by the week and delaying delivery dates is not cool either.

*YAWN like that ever stopped anyone in the bitcoin world before...

Oh wait thats what Yifu did to all us Avalon Batch 2/3 guys.  Chips just disappear out the back door and all of a sudden "delays" turn a 100BTC investment into a 60BTC return...  Hate to say it but most likely those chips are the exact same ones as the CoinCraft A1 and the fact that Bitmine.ch has a backlog they are working through when these chips are just available on the market just shows how inept and/or corrupt they are.  Avalon ran 3-4months late, I haven't been keeping track what month of deliveries has Bitmine caught up to now?

Sorry but 1TH should be $2500 by now, my cheap ANTMiners I got in the first 1.45BTC batch make me wish Bitmain would have continued his historical price drop "curve" - heck I wouldn't pay more than what bitmain sells ANTS for these days which is 0.98BTC for a 200GH rig.  So basically $3200 tops but really under $3K I would bite.  Everything else just seems "meh".

I can't speak of the Dragon miner, though ours seem to have come from the same factory. Ours have an English interface however and different branding too.

We've had some from the first batch running on-stop since the 10th of March. No issues at all.

If you'd like one from a reputable vendor you can purchase here - 28nm 1TH/s Bitcoin Miner $4,999USD + shipping. The second batch is due to arrive on the 18th and dispatch the 21st.

Edit: In case anyone is wondering our cost price does not even come close to having a 3 at the beginning

This 1TH/s miner is using illegal fake A1 Coincraft ASIC based miner produced in China. They are being sold on the black market in China illegally and without Bitmine's permission: http://bitmine.ch/?p=5178

IF YOU PURCHASE THIS MINER THEN YOU ARE PURCHASING COUNTERFEIT HARDWARE AND IN MOST Countries that is considered illegal. Just trying to warn people because we have spent a lot of money on genuine A1 Coincraft chips that we purchased directly from Bitmine at the end of January and we know how much they cost. There is NO WAY that the ones being sold in China for around $4000/miner are legit. It is ruining the Mining difficulty for everyone else for people in China to be stealing Bitmine's intellectual property and selling it for less than the bulk price directly from Bitmine.ch

There is no guarantee that those chips will perform to Bitmine's standards and they are definitely NOT real A1 ASIC chips. Check the price on Bitmine's website yourself for purchasing 500 chips. Their pricing is $43,750 for 500 chips which comes out to be $87.50/chip

How can people in China afford to sell 1TH/s Bitmine A1 Coincraft based miners with 40 chips per miner running between 25-30GH/s per chip for only $4,200 to 5,000? The 40 chips alone cost $3,500 (40*$87.50=$3,500)

This $3,500 bulk purchase cost of the 40 A1's from Bitmine does not include the cost of manufacturing PCB's, cases and the rest of the parts for PSU's, cooling, Raspberry Pi, etc...

The math does not add up so I would be VERY CAREFUL of buying those illegally produced A1 chips! It is like purchasing a fake iPhone. It may work for a little while but it is not the same quality as the real thing. Help stop this criminal activity by boycotting the sale of these fake A1 Coincraft chips from China.

Nice. Its good to hear about those miners running well. I am planning to find the factory and do a group order. I plan to be very transparent with the numbers.

Is anyone interested. Please PM me. Thanks

About to hit day 4 and my unit that arrived on Friday is still running at 1Th/s without any hiccups and less than 0.2% HW on BTCGuild.

I have contacted the manufacture, you can buy the dragon at around 5000 USD+Shipping from China.
If you guys are interested, I can probably arrange a pre-order.
However, I personally don't understand why so many people are still mining BTC?  Scrypt mining is way better in any perspective.
