yeah we are hitting the wall as diff is going sideways and we are creeping down to where only 2-4 cent power works.

and last but not least a bad auc is possible

but in your case 741 can not and will not run 821

It is not useless to mine it on solo.ckpool.org  if he needs heat in his space and is mining vs a space heater.

While he won't ever make money here unless he hits a block  and gets a small bonus well under 100 usd.

If he needs heat and points it to solo.ckpool.org and hits a block he gets 12.5 coins.

IN either case   the odds against him  are more then 100,000,000 to one   but  if he was going to use a space heater   he would hove 0 chance.

So would you like a 100,000,000 to one chance at a block  or a zero chance.

The problem with pointing here is he gets 20-100 usd for hitting the 100,000,000 to one chance.

So he should point it to the solo pool

so you really want to learn if you do
don't point it to this pool

point it to this pool

http://solo.ckpool.org/

this is a free lesson.

As the the teacher of it  I will ask you to do it and post results in this thread

https://bitcointalk.org/index.php?topic=763510.0

feel free to pm me  with questions as to why you want to point that  gpu to this pool  http://solo.ckpool.org/

and not this pool http://ckpool.org/

As it is absolutely true that  for some people  using a gpu to mine at solo.ckpool  makes sense   while it is next to impossible to argue that mining  a gpu at http://ckpool.org/ makes any sense at all

So I will be willing to teach you this lesson if you are willing to point the gpu at http://solo.ckpool.org/

and post about it here:

Monday the 15th which I would have liked to think was a shot at a refund.  Since it is a weekend beyond the 11th cutoff date.

I was not refunded

the only orders ever made and paid for   Are  in bold type above.

those bold type ones were about 0.130 btc
and I have no refund for them.

As of today  no one has shown working gear in their possession.
No on has show proof of refund.

A few emails save some hosting gear has shipped to a hoster.  


I really wanted to think this would work out better then it has.

So far the best thing that happened for me is order system worked very poorly  preventing most of my orders  from taking place.

I will not post an update until this friday.  Unless I am refunded.

old news so I am locking the thread

925 is a bit too low. My projections show me a low cost or free power guy should earn in under 6 months at 1050 price.


Even  possibly as fast as 140 days.  So I am at 1050 for  3 of them with wires and controller not 925.

Now I realize you need 0 cost or very low cost power to roi them.

 I am hoping some has that and asks me to sell them.  At 1050 or close to that price not 925.

they can clock to 900 watts or to 1350 watts   they can do 9th to 12.5 th

Back to back blocks with a snap of my fingers!

A lot depends on its down clock ability.

the 841  was great to down clock and you could increase efficiency at low settings

the 851 was great to upclock its best efficiency was at full speed.

so if the A911 is tweaked like the A841  it will be good to down clock

if the A911 is tweaked like the A851 it will be good to up clock

common sense   says to tweak it like the A841.

I am eagerly awaiting a reply from Steve of Cannan to see if they have some for me.

yeah 49th at 5400 watts = no good  for many ,but it will work on a 30 amp 240 volt circuit.  

you need 2-4 cent power to consider having it.

although I see sideways movement in difficulty for a few months.  maybe it works for a six cent miner

Well if it is like the R4 that was pretty quiet when downclocked just a bit.

But 1440 watts and 18000gh is 80 watts th.

I hope with a down clock it can do under 80 watts a th.

The key is the next two jumps after this one.
Along with BTC price.

if price stays at 6000 - 6500  I think we continue to drift sideways.

Hosting could be an option but it has a lot of hidden costs and issues.
For me if I could have a nice generator with free fuel I think I would mine before I host.
Or cut a deal with one guy looking to dump his miners.

Let’s say he gets a good 50kwatt generator. And one guy brings him 30 s9is.

The deal they do is 50-50 on the coins mined.

His cost is the 50kwatt generator. He gets the coins from 15 machines.

The s9i guy gets free power for 30 machines and keeps coins from 15 machines.

This could work for op.

The gear will always earn money.

yes it is.  in fact I would love a 800 watt 12th miner

if the A911 is close to this I will get one and review it.

In my house which can use heating from now until may

an a911 using 800 watts and doing 12th would be nice.

@HagssFin
As for A911 as a native New Yorker that lost a relative firefighter on 911 maybe I would dedicate this to him.

I have 3 used avalon 841's up for sale

https://bitcointalk.org/index.php?topic=5049376.0

don't go for the t9's

and other sellers have used s9's

this is a good deal below

https://www.ebay.com/itm/Bitmain-Antminer-S9-13-5-TH-Bitcoin-SHA-256-Miner-Pre-Owned/202450059173?

and he will give you 10% off if you buy 4

so 4 x 300 = 1200 - 120 = 1080  or 270 each

if they paid the vat.  no one knows if they paid it or said they paid it.  so far no one has received the gear.

Now when a European  buyer gets one and says I prepaid vat and have not been charged a second time then you would be fully correct.

At the moment you are hopefully correct.  To anyone that paid prepaid euro vat for the gear.  please  make lots of copies of all the paperwork you have.

as of today my 2 orders are marked paid not shipped not refunded not cancelled.

I will update on and off at least once a week. Until  they refund or ship it.
