We use A2 chip and will provide 60mh/s (5 modules) and 75mh/s (6 modules). More details will be released.

Price ??

How much ?

Update:

The speed we use to calculate here is about 1.55M. Right now, it can go as high as 1.9M.

Price  (not include shipping etc and power):

75M (6 modules) - $12500 or 25 bitcoins
62M (5 modules) - $11300 or 22 bitcoins
 
Not include shipping and PSD. Price are negotiatable with quantity.

Shipping Time:

We can ship from 5/4-5/5 timeframe.

Size:

It is exactly our 1T Bitmine size (5U high, and 19" standard rack wide)

Wonderful

Where to buy?

A suggestion sell a lesser model .  the price point is decent if it is real . watts are also okay.

but shelling out 25 bit coins is a  bit steep for 1 piece of gear .  right not the grid seed blade is 5mh sells for 1500 . you offer 15 x the hash for about 9 x the price.

that is pretty good .   but I have to think a 15mh unit or a 20mh unit for 3k- 4k would sell better.

As a buyer that tops out in the 3k price range  i can't really hope to buy from you. unless I wait  until the model drops in price or you build a smaller device.  Say the size of an ant miner s-1.  I would think selling a 15mh machine for 3k would be easy to sell.

May be we can have system that have one module for $3500. You can buy extra card to plug in at future.

We can pick up payment in US and Europe.

website?

well I am with you a website with some details would be nice.  and a seller willing to sell an expandable  device that allows adding of modules one at a time would be really good.

It would be nice to see this pan out.

Shipped with 1x 15mh module and no psu  just add your own would be a really nice way to market the gear.  since a module is around 150-180 watts. most any ATX PSU  could be used at first. Although I have about 7 spares psu's from GPU mining.
  T
HIS WAY OF SELLING  allows me to plan for my in house summer mining .  get a one module setup run it for the summer and then expand when the weather cools off. This will be bookmarked.

Our website ( www.jtminer.com ) only has information for the 28nm JTminer's Bitcoin miner. There is no information about the 28nm ASIC Scrypt Miner on the website right now. We are the first to put the 28nm bitcoin miner into mass production. We use the similar design from the bitcoin miner to produce Scrypt Miner.

We will keep this thread updated. Message skyfromwell or this id "JT miner" for purchase inquire. 

We will update the price if we decide to provide the miner in the range of 1 to 6 modules. Thanks for your suggestion!

how can we make order? and when u guys will shipping ?

shipping time probably around 5/4-5/5.

I will prepare a foreign account for order taking.

Just remain guys, I just send a JTminer Bitcoin system to Luke-Jr for software development. You can email him to verify we are honest company.

And we don't want to do pre-order etc., so wait for our system ready to ship before you send money.

Unofficial group buy thread: https://bitcointalk.org/index.php?topic=577534.0

Hey, I don't mean to poop on the party but: KnC is selling the mini Titan (150 Mh/s) for $5.5k or 300 Mh/s for $10k.

 $12.5k for 75 Mh/s?  Assuming a one month head start is worth about 10 BTC, you guys are still betting that your technical + business rep is better than KnC's?

A2 chip is come from same family of A1 chip.

It will start mining at May, and I don't know KNC can come out at end of Jun. So 2 months head start and with the numbers out, KNC system will do nada at that time.

how many will be available?

This is a second reason that my idea of a 1 module machine with out a psu would sell.

 I would spend 2.5 k maybe even 3k  for a 15m machine that had no psu and 4 empty slots for expansion.  I can mine ahead of the curve and if I desire add modules one at a time.

The builder has an easier item to ship safely  yeah same size but mostly empty inside fill it with safety packing.  you the owner adds a psu and you the owner can decide the correct time to upgrade.

A gridseed blade is around 1500 and 5m.

 so a 15m machine at 2.5 to 3k delivered working by may 5-8  is far better. I realize the builder needs a price point to make money.  

We all would buy this at 100 bucks and the builder would go broke.  So somewhere in the 2.5 to 3.5k price range there is a good number for the buyer and the seller.

as the buyer you can adjust to the price of the gear dropping.  I have 30 5 chip gridseeds.  first one I purchased  was 350 usd.  the last 5 I purchased were 102 each.

I could do the same with a machine with space for 5 modules. Buy high and as price drops add one or two modules at a time. Also i avoid too much watt use in the summer coming up.

1 module is around 180 watts.

This is where mining is getting more interesting. Last Friday GAW had a one day Gridseed 5 sale for members for $86 ea. For $3.01k you could have bought 12.6 Mh/s . I think also with cloud mining being used to instamine new coins, this is finally putting pressure on the hardware vendors.

I have total 200 units of it for 5 modules calculation.

I can do $3500 with a system with 1 module, 5 umpty slots for upgrade.

Stay away from this overpriced shit...

You are selling twice the price it's worth...

Every sim I've done are telling me that there's no way you will ever see roi on these...

pics? website?

You're absolutely right but they won't listen to you.
I always try to warn people before ASICs but somehow nobody cares.
Why don't they try to do the math before investing in something? Ok let's do some quick math for them:
- Average payout per Mhs @ wafflepool 0.006 BTC/1Mhs/day
- 72Mhs would get you: 0.006 x 72 = 0.432BTC/day
- Profit for one month: 0.432BTC/day * 30 = 12.96BTC
- If you pay 25BTC then its ROI = 2 months.

So if this was so easy they could print money themself and won't need to sell us people.
Ok but I don't care anymore. Just buy this and have fun yourself, hopefully.

I just know what it called: It calls GREED.

Just my 2 satoshis.

Regards,
 

two months?after may ,the net hash rate will be increased huge ,i don't think so for each MH will get 0.006BTC

Expensive? Yes. But still cheaper than GPU, right?

Friendly remainder, since A2 is made by InnoSilicion, please check with them to verify partnership. We are JTminer. If you see some others here, need to check too.

Update:

We just verified it can run on 1.9M.

With this in mind:

91M (6 modules) $12500
76M (5 modules) $11300

15M (1 module) $3500

Good deal IF and only IF you can ship it within two days like bitmain s1  ;D
Unfortunately no company dared to repeat bitmain's in-stock model, even bitmain is lowering their level a bit to their competitors standard with s2 preorder model.
If i recall correctly you were the company who tried to sell for 6000 us$ back then when everyone offered 4000$   :D

We are NOT require prepay for orders.

Currently the chips will arrive before May 1 (which is a Chinese national holiday) and we probably need few days (4-5days) to have everything ready.

So if you are interested, just put your desired quantity and contact info with us.

You can either pay for ship or come to our factory to pay and pick up.

No more pre-order shit.

Same chips only they say a2 - this looks like a photoshpped image.  Photoforensics website shows metadata on 1/1/2014 which is a long time ago - why are there no pictures of working prototypes nor videos of such.  You went so far as to put your own personal bitcoin mining address here - you didn't bother to keep it separate for accounting sales activities = this isn't a legitimate business practice. Zero pictures of a working product, just a screen that says 75 MH - yay. That could be created from using an old nvidia card mining BTC guys.

Please demand a youtube video that shows a working prototype and an explanation as to why the chip looks exactly like the coincraft a1 chip.

A1 chip is for bitcoin and A2 chip is for scrypt miner. Both chips are developed from innosilicon.com. From http://bitmine.ch/?page_id=863 (http://bitmine.ch/?page_id=863), it says Bitmine’s Coincraft A1 is a third generation Bitcoin Mining IC developed by Bitmine in co-operation with a team of expert engineers from Innosilicon.   Both of them can sell the A1 chip. "Coincraft A1" is not equal to A1. Please contact innosilicon or bitmine if you have doubt on A1 chip.

Please do not distract this thread with other stuff. You can open your own thread if you want. Thanks.

The 15M $3500 is moving in the right direction.

I agree that giving an upgrade option should make this more attractive....watching.

If you guys really want, just reserve with sales@jtminer.com or contact with JTminer.

Escrow ?

This one is interesting but overpriced at the moment. For comparison, it has the performance equivalent to ~2.5 Gridseed blades, which would cost ~ $3750 (1500 x 2.5) and are in stock right now.

indeed, $1500 for  10M should be enough

Last call for 5/5-5/10 delivery and it is in a VERY limit quantity.

No escrow, and we can arrange local agent to meet with you.

Only 10% deposit is needed to be transferred to secure your reservation.

In another thread you stated you are not accepting escrow; however, before most people send $12,500 people are going to want to see proof of past sales and customer feed back. 

any chance of pickup in shanghai? or china?

No escrow, no pre-order, only 10% deposit.

Sure. Please check your message.

Update:

4 modules $8000

What is the hash rate, power consumption, ship date? Is a power supply and controller included?

It is exactly as you see in video but 4 modules.
Hashrate I'd definitely 57m (1.8m per chip), but can go higher at 60m(1.9m per chip).

Single chip is 10w, we only measured the wall at 650w for 6 modules.

ship date? Is a power supply and controller included?

Yes. Ship around 5/5-5/10.

Is a power supply and controller included?

Yes.

A few questions:

1) Confirm that the 1 or 4 module offerings can be upgraded to the full 6 modules with the addition of hashing boards, and that other than the fewer hash boards there is no difference

2) Further confirm that the power supply on the 1 or 4 module offerings would be sufficient to power the full 6 modules if added later

3) Confirm that you plan to offer hash boards individually as upgrades after the initial system orders are filled and provide estimated pricing for such upgrade modules (remember, KNC played the upgrade trick and then never offered price competitive upgrades so it would be helpful to get a commitment from you).  Presumably pricing for 4 modules would be less than for a 4 module system .. how much less based on current pricing?

4) If miner is not shipped by 5/10, will you refund the 10% deposit?

5) When you call for payment of the other 90%, will the units be shipped next day after payment in full?

6) Is the firmware root accessible?  E.g., can I log in/SSH as root to be able to tweak and upgrade the miner software or is it locked?

1) Sure, it can be easily upgraded.
2) Not sure now, I will update when I know the answer
3) Not sure now, but around $2000
4) We could return some money for compensation if we could not ship out before May 10 (not delivery date, take a few days for DHL). But the possibility for delay is almost zero.
5) In 1-3 business day for processing.
6) Not sure, the possibility is you will have the access.

Skyfromwell will give a formal updated answer later.

Price specification:

module   lower hashrate   upper hashrate    price ($)       bitcoin
                   (MH/s)           (MH/s)
6          76.8                    91.2                  12,000            28.57
5          64                       76                    10,000            23.81
4          51.2                    60.8                  8,000              19.05
3          38.4                    45.6                  6,500              15.48
2          25.6                    30.4                  5,000              11.90
1          12.8                    15.2                  3,500              8.33

Note:
a). The lower, upper hashrates are based on the single A2 chip's hashrate 1.6Mhs, 1.9Mhs. And 1 module contains 8 A2 chips. The real hashrate is close to upper hashrate.
b) The exchange rate is $420/bitcoin. It will be adjusted weekly. If there is 30% change in the price of bitcoin, we reserve our right to adjust the bitcoin payment at that time.
c) We reserve the right to temporarily change the price, also we have the right for the explanation of the price specification.

1. Yes.
2. Currently 6 modules wall energy consumption is 650w. So a single 750w power supply can handle all.
3. This is not issue. Only problem is that we have orders of 6 modules, 5 modules will fill out first.
4. Of course.
5. Yes.
6. Of course, you can tweak cgminer but firmware of MCU is very techincal work.

Could you please clarify the pricing a little bit. The price of each additional module between 1 and 4 seems to be $1500, but then 5th and 6th modules add $2000 each - why is that?

With Zeusminer's now doubling their hashpower via cloud based mining promotion im not sure what is the better option... 15MH for 3.5k mining for 1 month earlier, or 36MH for 3k mining one month later

quick math.. with current BTC price and wafflepool earnings per mh/day the JTMiner 15M $3500 unit would ROI in about 104 days, and with the Zeus promo their 18MH(36MH with promo) $2999 unit would ROI in 37 days, making the JTMiner ROI around August 15th-20th and Zeus after releasing May31st would ROI July 10th or so.

Let me take a look and talk with the company team.

Is this the same as what Lightning Asic is selling for $9999?

Yes.

I use the coinplorer profit simulator ( https://coinplorer.com/  ) to help with my purchase decisions.  I plug in the numbers from this popular spreadsheet: https://docs.google.com/spreadsheets/d/1msn9gC7wgBYdiyOLZLhQifOSKpt3ukdnuTy14m-F-s8/edit#gid=1966313813

Your quick math is pretty close. 

1st 91M system shipped to USA today.

Cool. is that one to Luke Jr for showing the world you have a working product?

We sent our bitcoin miner to Luke Jr for software development. This Scrypt miner should be sent to our boss.

Shipping is on time from May 5.

Thinking of making deposit pm me.

For Zeus, are you assuming that the cloud hash will start at the same time as your machines? but it's not, the cloud hash comes later. That makes a BIG difference in calculating ROI. Would you mind calculating again to see how long it'll take to ROI?

has anyone else here put deposit

not for this scam

A small video for the miner. More video could be produced if possible.
http://youtu.be/DnDZaAMJdko

so this is not working for asiabtc too?

Scam?

We already delivered a few miners for oversea buyers. And seems no one complain about our service. Also some full member had posted a few photos below. Thanks for his support again.
