He still hasn't received my bank xfer  just check my bank account, still not shown in my account by now, something must wrong here, you would better ask your bank for help, meanwhile, i will keep your miner and will send the btc mined to you when this thing is figured out |

i vouch for fire juan in this plan, and i will promise that all of the miner will 99% time online.

Thanks for your support guys, i will try my best to keep my word, it is the base of my business and i will not allow it is destroyed

 This is the board i need help sourcing, It says on their site the ship with extra. Anyone have any info on it? i can order them if you want |

 I just received my miner! I am now hooking it up to start hashing! I am very excited. I had to find a cord for use in USA though so be prepared if you order in USA. I will update as soon as I get it up and going! we will order some of the cable that can be used in usa, then it will be no necessary to prepare by yourself |

some picture of host miner  Very nice picture 李培才 . How do you keep your servers cool? Does one server's back caressing the other's server's front increase the heat? we have two powerful air-conditioner, each is 35P, and a powerful refresh air system, which can bring 12000 M3 new air per hour , so temperature will not a problem,  |

Just so everyone knows, did a wire transfer for my order on the 21st. Bank says everything went OK, but they can't verify it was received. PC claims to not have received it yet. I believe him to be honest based on my conversations with him. Will wait a couple of more days before I update you guys. Just be warned internation transfers can be a pain. Should have just purchased BTC and used it way more cost effective, and a lot faster.
i just want to ask you about your money, it is very weird,never shown in my account, all of other people's money who pay me via wire transfer have shown except your money. |

Thank you for your ROI analysis. Do you think Chinese government will shut bitcoin down for good? Hello, every one, I just get the inform from factory that the order of batch of 5 Apr is about to close
This is the last call for the order of this batch, and I will keep the price at 3150$(delivery miner) or 2800$(host miner) for paying me via btc directly and 3250$ or 2900$ for other payment method like paypal, btc with escrow and wire transfer.
This batch will arrive in my place on Apr 4, and i will send it to you on Apr 5 and should arrive in your place no latter than Apr 7. I know it is a hard time to make the decision because the low value of btc today, but here is my opinion on roi analysis.
ROI analysis
Many people make decision whether the miner is worthy to buy on ROI analysis , and i will share my thought on it with you.
First, you need to consider the following two questions:
is the mining itself will disappear after six month?
What is the speed of the fastest miner can perform after six month and what is its price?
I will give you my answer to these question.
is the mining itself will disappear after six month?
The answer is definitely no, only the bitcoin exist, no reason that mining itself will disappear, and like most of the people in the forum, i have strong faith on bitcoin.
What is the speed of the fastest miner can perform after six month and what is its price?
I can’t tell you the exactly number of that, but my answer is not exceed 2T with the electricity consumption of 1000 watt, during the last one year, with the appearance of ASIC, the hash rate speed you can gain with 1000 watt has increased from 6G to 1000G. But it is almost the best value we can achieve based on current technology. Although i am not an professional electrical engineer, i can see that the increase of the hash rate of the chips are closely connected with its manufacturing technology, which have been increased from 110nm to 28nm by now. But as i know, it is almost achieve the limit of current chip manufacturing technology also the limit of physical law. Although 20 nm manufacturing technology is possible but the cost will also increase rapid and may be not worth to use. So we can achieve the conclusion that the life time will more than 6 month.
Now we can go forward to the second question here, what is its price.
I cann’t answer this question exactly also, but i does know that its price will not below its manufacturing cost. That is very simple to understand, the factory have no reason to sell them unless they can profit. As i know, the manufacturing cost for one dragon 1T miner will not below 1000$(chip, psu, Raspberry Pi, fans, shipment fee, all these thing need cost and will not disappear) .
Now we can go back to the ROI analysis, for most of the roi analysis, it will assume one miner will only have 2-3 month life, but based on above analysis, we can see that will not happen, so there is must something wrong with the current ROI analysis.
Here is my third question, what is the the most possible number(in %) of the adjustment of difficulty for one round (12 days) in Oct 2014?
I will give my answer later, but now, i want to hear your guys opinion
That possibility is exist, but, it seems like that not following the claim toward btc last year. |

all of the miners in the batch of 29 March(32 units) has been delivered today and the track no have been send to your contact email, all of the host miner also have started to work for the owner.
Never realized it is a tough mission to do this, and i am very tired and did not eat anything for the last 8 hours,Thanks god, i have successfully get the last 5 miner to the express car just 5 minuets ahead the departure. i need some food and a sleep, and will back after that:)
Just wanted to thank pcfli for a successful group sale. My hosted miner went online on time and with very little drama. I waited until there was some good feedback on the early batches and I paid direct BTC to pcfli for a hosted unit. I'm not advocating doing that, its just the way I wanted to deal with it, feel free to escrow as needed. But I just wanted to let people know that, from my perspective pcfli is straight up and doing honest deals on these miners. Its output pattern is oscillates slightly but is pretty comparable to other ASIC miners I have tested or used doing anywhere between 900Gh/s and 1.1Th/s This is the output after 2 and a bit days.  Thanks for the trust and support. to be honest, i am not against the use of the escrow at all, but the quick change of btc value is a huge risk i need to take, just like in this batch, the money for 11 miners is still held by ognasty, almost 150$ has lost on each btc, and for a miner valued more than 6 btc, it is 900$ lost each miner, and thus leave no profit at all. although i have faith that the btc value will back, but i cannot wait because i need the money to buy new miners. That is why i am willing to give some discount for your guys who pay btc to me directly and hope you can understand my position |

Anybody having weirdness with their LCD? I'm trying to track down a problem, but the vendor is non-responsive at 3am China time. One unit has an LCD that is blinking Red/White on the LCD, and it's a bit unnnerving. If anyone has some insight before China wakes up, it'd be appreciated.
As i know, it is caused by the wrong position of temperature sensor, it not effect the hash rate, but just like you say, unnerving, and maybe lead to failure of the over-heat protection |

Getting very frustrated with my dragon. It starts up and will hash great for about an hour then goes to completely zero until I come back and reset it, after that it takes about 10 minutes for it to ramp up to full hashing. Will run great for 20 minutes then go back down to zero. I have a lot of other miners running so its not my network, or power. The Dragon doesn't completely turn off it just stops hashing out of the blue. Anyone else having this issue?
keep looking the temperature of the miner and the real time monitor data |

On the miner config page what does the "mining difficulty" pull down mean? Mine is set to 32 right now, what should it be at?
it based on the pool you chose here is the official suggestion GHASH :32 , btcguild:128,256 |

Can anyone get single blades? I want to add another psu to all my units and put 5 blades in them. I need 7 blades if anyone can get them.
i suggest you would better to test whether your plan is possible first and then buy the blade, if your plan works , i can order some blades for you We tested 5 blades in a 4 blade unit with a EVGA G2 1300w- worked well and did ~1.25th Thanks for the information |

Hi pcfli, received tracking number  I'll be interested in more next round, possibly hosting if you've got spare places at data center. thanks for your hard work cheers we have cooperated with another new data center now, it is just built and the hardware even better than our current one, so you are free to buy as much as 150+ units for host now |
