The completely evaluation of Dragon 1 T bitcoin miner from china

[samsonn25]

As i know, the chip is A1 indeed, they buy it directly from the factory who produce them. bitmine is the only company who have the right to sell A1, the factory of china who produce it also have the right to sell them, that is what happened now.

Interesting. As far as I know, the intellectual property belongs to bitmine and they have not given the Chinese packaging facility the rights to sell these chips.

From what your saying, the chips were not bought from Bitmine. Until the legality of the chips can be better ascertained, I would be very hesitant to make a purchase as being in possession of or receiving stolen goods is considered a criminal offence in most areas.

There are millions and millions of chips leaving chinese factories real or not, authorized or not, copies or nor that is why the hashrate is sky high.  Avalons Asic, etc.

You need to know the legal status of your chips. If they are counterfeit Bitmine could get a court order to request Customs seize and destroy your miners on import, ask Trading Standard to remove and destroy them from any business premises, and ask eBay to remove all listings for sale no matter who sells them!

By that time in 9 months the chips will be outdated.   Mining difficulty 100 Billion.

That's a pretty cool (literally - check those temps) miner; courtesy of the slightly noisy fans, perhaps, but those could be swapped out.

It's now 19999 Yuan = $3255 USD

Heck shipping on this unit should be cheaper than the Ants one package.

They should be able to beat the Ant prices for sure.

Edited for content, I see others have purchased these machines.

If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip. So the question comes: Does the "Coincraft A1" chip means "A1" chip？I don't think so. This is something like Mcdonalds can make their hamburger and KFC can make their own too.

We do NOT buy chips from bitmine and have no business with them.

From that link:

Designed from scratch, 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.

Doesn't say bitmine bought the chip from a Chinese company.

I'm assuming that the R&D funds came from bitmine and it's customers and that Innosilicon was contracted by bitmine for R&D, ergo, bitmine retains IP rights of the A1 chip. Unless the use of the A1 chip in these Chinese 28nm miners has been authorised by bitmine, what we're seeing here is corporate theft and entities being in possession of or receiving these miners, liable for a criminal offence.

Precisely, we are the owner of the IP inside the A1 chip and the major contributor to the know-how of the inner workings that led to its development. We are aware of things like the one happening here and we even made a press release news concerning this matter:

http://bitmine.ch/?p=5178

Whoever purchases these does that on its own risk and may be liable in its own country since we hold IP on that.

Yes, that's China.

I have been in contact with pcfli today and ordering a unit with escrow. I will do a complete review of it, if it arrives this Friday as he claims.

@warhawk187: Perhaps you are unaware, but you have just potentially incriminated yourself.

These current Chinese machines based on the CoinCraft A1 chip belong on sites such as Silk Road and customers should be mindful that just because a few units were received and reviewed it does not mean orders can be fulfilled on an ongoing basis.

Then please delete my original comment. I did not read that part of this thread, nor do I condone any IP theft.

[SUNcoinDEVs]

Miner arrived today as claimed by pcfli. This thing screams like a jet engine, and weighs as much as one.

Will have to replace with something quieter, and I thought the Antminers were loud.

Also, for US people, have a spare PSU AC cord rated at 10A or greater for a 1000W PSU, the original AC cord is China CPCS-CCC (Type I). Luckily I had an extra EVGA Gold 1000W PSU not being used, so I used the cord from that.

Interface is all in Chinese, but luckily when on, the front screen tells you its local LAN IP. Thank GOD for Google Translate, I had it configured and hashing in less than 5 minutes once but pcfli supplied documentation beforehand.

Hashing at 1Th/s as claimed on Eligius:

I will post pics and a full review later today.

X2 5 ants cost 5.5 BTC right now for the same hash rate. I would pay up to 6 for the extra efficiency but couldn't justify more for the short life of the returns.
