I agree about the patent dispute https://bitnewstoday.com/news/technology/patent-argument-can-potentially-reshape-the-mining-market-in-china/

Key point of the Patent of course is Bitmains claim of uniquely using string topology to power the ASIC's. Problem with that of course is that as basis of the dispute is that other people (Bitfury) had been using string topo a year or more before Bitmain did. After Bitfury, came ASICMINER who also used it as I recall.

Problem with *that* being prior art.... Well, Patent Laws in different countries are - funny. String topo not being previously patented much less a prior patent being filed in China on it leaves the door open for interpretation by Courts... I for one hope Bitmain loses on the matter of "Serially Powering a Chain of Data Processors".

What would happen if Bitmain looses dispute? What could outcome be? That patent becomes public and people can start using it, or Bitfury becomes Bitmain, meaning in therms of 1st hand miner sales. Not sure what to expect from this :S

It won't affect us if they lose. Only future machines if they fail to license or fail to produce.

Patent argument can potentially reshape the mining market in China

Chinese SIPO, or the State Intellectual Property Office of China will be reviewing a complaint from Yang Zuoxing, the former director of design in Bitmain, the vast and very influential mining corporation. Yang Zuoxing is currently leading a rival company by the name of Bitewei. Chinese legislation allows to revoke the patent as long as the complaining party provides all necessary proofs that it, indeed, was the one that invented a discussed innovation in the first place.

Bitmain, in turn, filed a lawsuit against Bitewei, claiming it is trying to infringe Bitmain’s patent rights. If Mr. Zuoxing succeeds, Bitmain will lose patent rights for a key mining component and the market in China will never be the same again, which is absolutely not beneficial for Bitmain and explains why they bothered to file a counter-suit. Mr. Zuoxing tells he expects to hear the decision of Chinese authorities in three months.

China has always been a mining frontier due to the very well-developed electronic components manufacturing in this country. It is much easier to build mining farms and found mining companies in a country that makes electronics and hardware for the whole world, including.

Bitmain maybe try to clear the stock with such massive selling in this several month and speedup the production in three month before the decision.
I think its a good thing that bitmain to stop the supply temporary.

its back for sale +$200 and 2 weeks later shipping, not sure about payment tho I have yet to try and check out

I have just checked it... Its only BCC Sad

It looks like, i will buy now BTC, wait for the fork, and order after that. Since its BCC only AGAIN, i guess sale will be open for few weeks like the other one(13.5 TH/S)

S9 have been available for sale on Bitmain for a couple weeks as long as you have been willing to buy with BCH. Today they are "Out of Stock" on Bitmain site and these offers for sale suddenly appear here. Coincidence? Or Not? It sounds like a scam.

In this case Bitmain wouldn't really be adding to the parade of red flags hanging from this offer already Wink

Hi, I sell 8 pieces of S9 miners, they have another 3 months warranty, I want for one miner $ 670, if you buy all at once sells cheaper, if someone is interested, let me know, all documents for miners also have, you can apply to my electronic address [email protected]

I've send you a PM. I know that you are newbie, and everything is suspicious. If you respond to mail, and show some pictures that this is possibly true. We can use Escrow and do the transaction.

It’s a pretty obvious scam, nobody in their right mind would sell an S9 for $670 and chances are he will not take escrow and will ask for you to send your money first. Plus his account is brand new. Would not trust him at all.

I am not falling on "first pay" tactic Cheesy

1st thought should be to Google 'convert watts to BTU'. Why does no one seem to know how to use search engines....
FWIW, BTU/hr=Watts x 3.4129

The CFM, fair question. Don't think there is any data on that. I believe the fans move 250CFM free-air but under load, pure guesswork. I'd ballpark it as around 150CFM

I didn't know figuring out BTU was as simple as plugging in the number of watts, I thought it was different for every machine. Some machines are less efficient so they put out more heat per watt, some are designed better than others so they put out less heat per watt, etc. was my line of logic.

The miner efficiency is irrelevant and only compares hash rate to power used, has nothing to do with heat load.

For any electric power heat source they are all 100% efficient. Power in = power out as heat.
Cooling is of course another matter as it involves work moving heat from one location to another, not creating heat. In that case efficiency does matter but only in the sense that it takes x amount of power turned into y amount of mechanical energy (with losses turned into heat) to move z amount of heat energy.

Hi, I just wanted to double check this and clarify that it is still correct to say that 100% of power in = heat out for the antminer.

See: https://physics.stackexchange.com/questions/132026/is-it-possible-for-an-electrical-device-to-generate-more-heat-than-another-using

According to that, a device that is less efficient at converting input power into light, motion, work etc... will generate more heat than a device that is better at converting power into motion, etc.

Given this, is it still correct to say in the case of the antminer that 100% power in = heat out? (or something close like 95% power in = heat out since i would guess the device would not be 100% efficient at converting power into heat).

My best guess is given that there are no moving parts (except for low wattage fans) on the antminer, that probably close to 100% power in would equal heat out...?

Thanks for your thoughts!

almost all the energy converts to heat . 99.0% ? most of that stays in the room where the psu and the miner is located. unless you vent it.

the small amount that leaves the rooms is in the signal on the ethernet cable. and if the cable goes to a switch in the mining room I would argue that it is 100%.

and the switch is sending the energy out of the room not the miner

the fans produce heat and the move the heat they produce and the heat the miner produces. maybe 10 watts in the mother of each fan. if you measure the motor of the fans they are warm but the fan blows the heat away.

Information does contain some energy but for all practical reasons 99.9999999999999999999999999999999999% of the energy is converted to heat. That is rounded up alot so please don't use it as perfect.

is anyone having trouble with their orders placed where there is no payment confirmation and nobody gets back to you on the support pages or support logs?

is there a way to get hold of someone who can help.

Be patient. The order confirmation will come through in a couple of hours. Their system is slow.

I'm waiting on the same thing. Placed and order, paid, but the BCC chain must really be moving slow. Order expired before BCC posted there. Sent a message to support with all the info and TX numbers. Waiting to see if they are going to change the order from Expired to Paid, refund the BCC or try to screw me out of the BCC...

Anyone else have this happen?

yes and they did fix it fully
