Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

same here...


paid, unshipped,expired

If it doesn't change just contact their support or tweet to them. Bitmain is notoriously slow with support but they'll get to you eventually. Kinda sad Bitmain won't even support the only chain in which they accept payments on unless EDA is on.

Anyone have a coupons for sale?

How it's work to SELL coupons?

Is it possible? I mean BITMAIN allow to sell?

Well "sell" may be a simple term.  If you have a coupon you can "donate" it to someone.  Often times people will donate the coupon to someone else for a small fee.  That way both parties benefit from the coupon.

- use the app Coinomi

Hey guys,

is it not possible for bitmain to ship to Turkey? It´s very strange because they even can deliver to turks and so on...

Best regards

I can sell you   1 bcc


but you should belong to an exchange

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!

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

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.

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 anisovaleksandr1990@gmail.com

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

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

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
