28nm ** 1T ** 900W【JingTian miner】 in production !!!

[JointDoctor]

Bitmain and their Ants are definitely what all vendors should be aspiring to; good price performance and 100% legal. It goes to show that not all Chinese companies are the same and that one should be vigilant against companies like JT, JianTian, Dragon, etc who have no qualms with using stolen technology in their products.

Frankly I don't see any reason why anyone would want to purchase anything based on the A1 as currently it simply isn't a competitive option.

Sir, may you please remove yourself from this thread?
You´ve made your claims, multiple times now, and since it´s quite obvious that you don´t have a clue how patent/copyright works in the REAL WORLD you´re just making a fool out of yourself.

Innosilicon is a respectable company.

Lesson learned. Don't use Innosilicon ever.

So you're not going to buy any A1 chips from them for your Wasps then?

Because I can have double the hash power for the same amount of electricity. Not rocket science. Maybe the next ant will have the A1 inside or perhaps they are a big customer of Asicminer, that would make for a good partnership.

Agreed. 1T only 900W, ants can't beat it. Of course if you have free electricity and love the noises, that's different story.

Well, for what it's worth my unit went off to have a suitable PSU attached by friends of the JTMiner crew and has not been seen since...

Did you send it back to China? In such case, shipping takes a couple of days.
I know they´re working on the PSU situation in their design so we´re going to have some good news soon 

[jelin1984]

does anyone receive the miner?
or not yet??

Iirc ckolivas is an Aussie and had plenty of hardware sent in and out.  So put JT's penis down...  Lol!

Ive gotten 5 so far, one non factory, and 4 coming in the factory packaging with everything included (even a ethernet cable!!!)

@Powell: Can't believe such words coming from a businessman. Just saw a spoiled child and sour grape.

@bobsag3: You are not our authorized distributor. You just got some other brand miners, not JTminer.

Skyfromwell received a sample unit and just put it in his CA office since he can fix the cable. Someone will visit his office during weekend.

My thoughts exactly... all my other supplers have been more than upfront with me about everything on the unit- even had one come with a bad blade and I have a replacement on its way, along with a partial BTC refund for my trouble.

We value the brand more than the short-term profit. We are the first to apply the MCU in the 1t 28nm board and use high quality parts. We are not like other resellers selling the copycat and doing a price war against each other.

We have our own brand: JTminer. We will still put our effort on the research to get more powerful miner.

More JTminers are in the farm.

Unless your illegitimate A1 based miners are sub $3k, they're really not worthwhile for anyone to take risks on anymore. Game Over Man

BFL produced his first 60mn chip in China, which was immediately stolen and reproduced by Avalon.

Innosilicon is a respectable company.

What a FUD. They stole their product, reproduced it. Not the first time, not the last.

I you have a innovative BRAND NEW product, you NEVER go to China producing it. Thats a rule, American and European producers learned in the last decade, because they just steal and copy it!

Cointerra, Hashfast no way producing in China. BFL produced his first 60mn chip in China, which was immediately stolen and reproduced by Avalon. Ok, maybe you are in China RESPECTABLE if you STEAL A PRODUCT make alot of MONEY and anyone think of you that you are respectable. BUT THATS A FUD

Get your fact right before open your big mouth.

A1 chips ARE NOT PRODUCED in China. It is produced in GP facility in Germany.
It is designed by a Chinese chip design company with their own IPs. It signed a partnership with Bitmine with Bitmine paying for part of costs. As return Bitmine can have 100K of chips in cost price and can market as their own brand name.
Now Bitmine sold or used all those chips already. As a new agreement, Bitmine can only sell system not chips now.

As for respectable company, KNC also have their chips designed by a Chinese chip design company headquartered in Taibei.
