Bitcoin Forum

Finally I was able to finish the remaing order due to the backlog of Chinese new years mass.

1. Chips are ready.

2. Boards are ready.

3. Price is good with $6K due to good price discount on chips.

Later today I will give you website to play around.

Too expensive!

+1

No break even....

OVERPRICED

Will you have smaller units available?

For Example:

1/4 & 1/2 T units

I don't see break-even here, even with very optimistic params:

CUT THE PRICE

With quantity, price of course can go down.

Skyfromwell,
Why not price is so we can profit with it? Look at antminer, selling out every batch. What's more profitable, selling 2000 units for $3k or a few hundred for 6k? Think about it!

I understand but profit margin is thin so I have to really think what is best for us and for miners. 3k is not going to cover for costs, we do consider something in $5.5K range.

If margin is thin, do a short run and just farm with them yourselves. Save your energy and money for the next project or opportunity.

them was totally scam they only use black arrow chip,now the chips was lower price then they bought,them show me on mining result start from February,http://eligius.st/~wizkid057/newstats/userstats.php/1swrtyBsp9odruX65upeyubAVSAyggh78 (http://eligius.st/~wizkid057/newstats/userstats.php/1swrtyBsp9odruX65upeyubAVSAyggh78),around 60T on mining,if you buy with them,is not profit any more,they already get all the profit(coin） on 28nm before to your hand

Good luck then!

at this point,  anything > 4000 dollars/T is too expensive unless bitcoin price goes up a lot.

If you can't build a 1Ths miner at this point for under 3k US maybe you should stick to pirating DVDs

 :D :D :D :D :D :D

I totally agree.

At current price, for us, it is better mining ourselves. But since those systems are for next month, and I think the price of BTC may come up.

Website is here.

wasn't the price supposed to be 6k? also are you open to escrow deal to gain some trust from bitcointalk community? btw are these bitmine chips?

hi oswin,

Thanks for your input. However, it is really hard to understand your logic.

1) You said “them was totally scam they only use black arrow chip”, this is a serious allegation and you’d better have hard proofs. We certainly hate any scam as we are burnt before, but we do encourage the new companies which could provide real top line rigs to us.
As I know up to now, there are only 2 new 28nm ASIC rigs coming out soon, this is the one which has real miners running in a pool from the beginning of Feb and frankly you’ve to admit the results was very promising. Another one also boast to ship be the end of March, but does not have real rigs running yet, which means it’s still a toy in the lab and still a long way ( at least 1-2 weeks stability testing) to go from lab to mining pool.

2) You mentioned that “now the chips was lower price then they bought,them show me on mining result start from February, http://eligius.st/~wizkid057/newstats/userstats.php/1swrtyBsp9odruX65upeyubAVSAyggh78,around 60T on mining” , so what’s wrong with that? Actually I just checked their web site, here is quote about their testing miners, which is more clear.

“ In fact, since launched in January, more than 50 sets of JT Miners have been running stably in mining pools for half month without any crashes or hardware problems. The real life performance has been excellent: with 1TH/s hash computing power under low-power mode (can be overclocked as high as 1.2 TH/S under better cooling condition), the power consumption is 640W (ASIC consumption) when being tested on wall socket at 923W (can be optimized at 750W-830W in the newer version). These figures suggest that JT Miner is the most powerful and one of the most energy efficient Bitcoin mining devices utilizing the smallest silicon die area in the market. ”[http://www.jtminer.com/jt-miner-goes-live-for-sale ]

3) You said  “if you buy with them,is not profit any more,they already get all the profit(coin） on 28nm before to your hand”. What’s your logic here? Are you suggest that we should not invested any 28nm rigs because JT Miners have good ones? And you can profit if you get 28nm rigs from other suppliers? And how could “they already get all the profit(coin） on 28nm?” By the way, from  their website, at this moment, this company JT Miner seems mainly open to high volume orders from professional pools, we, as individual miner, need to see if we are lucky to get one in time.

And finally, would you mind to preview what you are writing before posting it to the forum? This is a professional forum and please show your respect to the forum readers.

good question, bclcjunkie, same questions from me.

when then new generation come out,most of profit is only first month in all kind of miner,and we all know all kind of miner olso profit in 3 months,so ever one know what i'm say here
if you pay for buy a new ferrari,you don't care for let the seller to ride you new CAR a month after to your hand?? come on say some thing reasonable to show me how pro are you here

Not accousing, but be carefull everyone

The message in chinese in that post seems fake to me. It feels like they are originally written in english and get translated into chinese using google translate. I am wondering who is really playing black PR or get paid for bad review here,  ;)

;)
Created account and went stright to posting here? Now I'm wondering who is really playing black PR...

Guys, ignore that guy named OsWin.

He is one sent out by MaxCoin people, and his main duty is to badmouth BTC and whatever related BTC.

The main message is that BTC is going to collapse and MaxCoin will take over.

This guy is very active on any BTC related QQ groups to bad mouth everyone.

He claimed that he lives in US (Silicon Valley). He also claimed that he will write a report to WSJ, and in turn that report will crash BTC altogether.

With his English. LOL.

Looks like a Chinese local promotor or MaxCoin guy.

He claimed that "1T miner will NEVER hit 4 BTC within 3 months". Then we showed him from Feb., 2, our 60T hits more than 240 BTCs now.

 ;) , no one will buy bad post/review from newbie, right? only from senior members

https://bitcointalk.org/index.php?topic=466254.msg5335037#msg5335037

People tend to distrust ANY new poster on these boards, whether they speak good or bad. It takes time to build trust. A history of meaningful contributions and good trading experiences makes one more trustworthy.

good point, KyrosKrane. We only focused on the fact not the bad mouth. I hope the miners companies could should more valid proof here, instead of only promises. I appreciate the fact that JT miner showing their real testing rigs running in a pool. I think this is valid proof that they have real rigs, and the stability and power consumption won't lie. We should encourage more companies to come out here doing the same things. I personally won't pay a penny until I saw the real running rigs showing me the promising results.

On this, I disagree.  A link to pool stats is meaningless.  They could have just about anything generating those terahashes on the back end.  Even worse, assuming they really are real and functioning miners, then the pool stats are proof that they're pre-mining with the machines until they're worthless, at which point they will deliver them.  Not encouraging.

Real proof would be a video of the mining rig running, hooked up to a PC (or whatever) and very clearly isolated from other machines. Real proof would be honest communication about what chips are powering the machine, how many per board, how to hook it up, what power requirements are, and so on, alongside the video.  Real proof would be sending the machines to a few different trusted board members (I'd suggest ckolivas, Kano, and Luke-jr as they're the primary developers of mining software, plus a couple of hero-level members with good trust levels and plenty of trade history) for them to run, evaluate, and post photos and videos.

This is a suspicious community, and with good reason -- there are plenty of new scams every day, and most of them start out a lot like this post does.  When proof of a working product is provided, the community almost literally throws money at these legit firms.  Sadly, the less experienced will also throw money at the scammers, resulting in many fleeced newbies. As a community, we're hard on unproven companies in part to protect the newbies, and in part to protect ourselves.  But prove yourself to be a valuable contributor, and you will be welcomed with oodles of cash and coin.

When ready would be intrested what chips are in these miners.

Great post.

And please be a little patient and wait for us to catch up with all those requirements.

I had to point to that post, because OP is unwilling to say what chips are in miners, has stated before that it's not bitmine A1, that the 'company' developed chips themselfs, but from the pcb picture posted we can see A1 chips there. How OP got them? If they bought the chips, why is that such a secret?

Let's talk a story, as in Hollywood movies and this story is all fiction and but based on true fact. LOL.

So it is just a story and people should not link their names with it.

At Wonderland, there is a guy named Good Digger who wish to have a powerful tool, so he can have a go on Gold Mountain. But he has no ability to make the core for this magic tool to work. So he looks around, far and away, in a place there is someone who actually have the ability to help him out.

So with hard cash on the hand, he found this guy named Good Maker to work out a deal. So he paid up front for some development costs and also for some portions of making the tool. As return, Good Digger will get his portion of finish product and of course Good Maker has the right on the tool and also keep a bigger portion of the magic stuff.

Of course, for Good Digger, he got some wonderful stuff and he can use them to make his powerful system. As a good marketing talker, he can also bloating around the miners community to show off his "invention".

But for Good Maker as a great skilled but low-profiled guy, he wants to make sure he really did a great job.

So he found his good friend the Good Worker to help up, by designing a cool system as proof to test his core is indeed a great one.

Then the design is come out very quick and successful. They put together 60 systems and let them to run a longer test.

At this point, Good Worker as a new comer to the community decide to let their design to go public, and at same time helping Good Maker to sell their great stuff.

So end of story.

1. Do you think Good Maker's own mining core is "owned" by Good Digger? The agreement pointed out both guys can named their stuff and can digging themselves or resell their systems.

2. Do you think Good Worker have Good Digger's core? Even both of them are coming from same design? So if Good Digger named their core with brand-name "My Magic", then of course, stuff from other sources are NOT "My Magic".

I will have one of these units later today, will crack her open and see whats inside.

Bobsag3, that one is not from me but a copycat who brought sample chips. He bascially somehow get some info of my early design that has a main defect in it.

so u already sold all your units?

http://imgur.com/a/tcimG

Will have an image of the rPi uploaded shortly as well.

Now we know who has been cashing-out all the BTC...

So... mining since January... with 50THs+... Now you can't get reward, so you are "selling" your used hardware, since you contributed to the fall of BTC value directly.

$6000 here in the forums, but your website you say $8000... And still pre-order.

Yet, for less, everyone is selling those same miners, also as a pre-order.

What advantage do we have by buying your over-priced used miners, or hope for the new ones that are pre-orders. I am not seeing the advantage here. You could make more just buying the existing miners, and reselling them.

I suppose you might have a good china-base... But at those prices, the units are not any kind of advantage to anyone in china.

Good to see you got them running, almost two months ago. Why didn't you sell them than. (Oh wait, I bet you did, and changed names. So you are using other peoples pre-orders, made a new company, get more pre-orders, change your name again, and have 2x more miners to dump on the BTC markets.)

Might want to try e-bay... (Though, I am sure you are there selling too, the same 50 miners you already have running.)

They are on ebay but not sure if resellers scam or actual Jingtian themselves.

I will sell same product for $300 discount, if anybody is interested.

I am not sure what can be disclosed. So I will wait for skyfromwell to update the information. BTW, our miners are NOT sold on ebay now.  You CANNOT have the same miner as ours since it is never sold before. Someone just copycatted our old design with defects and built a few sample miners. So be cautious.

people won't care for stories, about 'be cautious'. or who copy what. only thing is hardware in front of them working nicely, if cheaper they will buy from cheaper source who can deliver quickly

and the cheaper source is not ebay of course, i had kept eye on it before I hear of other reseller and your start this announcement days later

As guys here suggested, we are contacting ckolivas now, and if it is success, we will have someone fly to Australia with our system.

Meanwhile we send out sample units to USA and Europe now. I will try to get hold with Luke Jr for his professional opionion. Anyone knows how to contact with Kano?

Thanks.

KyrosKrane, I totally agree. Great point. Maybe we should start a new thread for fact-checking of new 28nm ASIC companies. It will be very helpful for miners to tell what's the promises/lies and what's the facts.

every 1 let see what the seller say on the china Chat room
when the price before collapse,all they want is looking some one to buy thoes miner,and now they looking was sell each T with around 4K usd(25000 rmb) to cover they lost,so if this not a scam or even like the joke? before i break they scam in china QQ chat room ,they was talking sell a miner like (ferrari) will keep profit 999 day mine until all the coin release in the world is that cool right??

I am in progress of reviewing a unit form jtminer.
There are some interesting details that have come to light.
I do not recommend buying a unit until a trusted forum member such as myself verifies their legitimacy.

So a trusted member such as yourself does not recommend purchasing these? 

Thanks.

bobsag 3 has one and likes it, and if greaterninja says it is a good product too. I would buy 1.

Price is too high. Ants are cheaper and deliver sooner.

Got that right.

Got 5 Ants from greaterninja 3 weeks ago, but I always like new toys.

I'm running a hosting company for 15 years now. And every time I wonder the miracle ways of setting up a simple website with 1 email adress to sell some miners. Three continents and 4 providers to get it work, or to get hide like minershare.net
So this company has indeed something to do with China as you can see. But for the transparancy, they better ordered a domain name including hosting and email by one single chinese company. When you ask that amount of money for a miner, payed upfront, it is better to show who you are, where you are, and that you have nothing to hide.

I haven't heard we have sent out the sample units yet. Maybe I need to get the information updated.

With me? :)

Since you and Skyfromwell  seem to be in business together, it doesn’t make sense that you would not know samples have been sent out...

What’s the chances of a forum member conducting an onsite visit to your production facility in China? Validation and verification... might build trust!
And your prices are too high; There is better bang for the buck with proven miners that are already in production and being shipped.
I imagine your miners are still in the testing and development stage; you have not ramped up production because you are taking pre-orders to
acquire working capital, and you have no standing inventory for immediate shipment.
How will you keep up with orders if you have nothing in inventory to ship?

Have one or two of these forum members conduct an onsite visit to your production facility in China; and you foot the bill.
 

Id be happy to make a trip out, need to go anyways for other business.

And if they pay for the trip, I can buy more miners instead :P

We are in different place, so I need some time to get the feedback. Skyfromwell knows the first-hand information. His words are more powerful than mine.

From my feedback, we have already contacted several trustful members. We will send out our sample units in 1-2 weeks.  I apologize if my words confused you.

We are in mass production for 1200T miners.

Sounds like a common problem of new companies as things changed so fast that even for the internal guys does not get the first hand information at the same time. Not a big deal. The most important is the fact that you do have solid miners for us. Since greaterninja and other trusted forum members are in process of reviewing your units, I'd wait and see.

Thank you for the clarification SeekSilence.
What are your thoughts on inviting one or two of these forum members to conduct an onsite visit to your production facility in China?

That's a good suggestion. If someone has a plan to go to China or has an agent in China and also a trustful member here, then feel free to contact us for an arrangement for visiting.

Hi,

Is shipping included with the price of the miner?

The price is dropped. For all purchase inquiries please send email to sales@jtminer.com or drop a message to skyfromwell.

I'm not a well-known forum member but I am an American located in China.  I live in Shanghai.  Is the factory or Shenzhen or Nantong?  I'm willing to visit.

Factory is in Shenzhen. Company is in Shanghai. We can arrange you to show the mining facility. That is near by.
