Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 240. (Read 531168 times)

Yeah.  I can't buy more unless I get a better warranty.

I have been told this may happen.
 Pay a premium for six month warranty will be offered soon.

The biggest issue with the S9 and all of these projections is the possibility you could be running at 66% (or god forbid 33% or broken altogether) before that year is out which I know goes back to the whole warranty point.  I have more than enough BTC to buy more and I have an S7 that I could replace with an S9 but I am way too leery of a hardware failure.  I need 2.15 BTC still to break even on the first two S9's so buying another and hoping I don't see a board failure before I mine back that much BTC is just too big of a gamble.  If these things showed a higher degree of dependability I probably would have already bought a third one.

 yes of course they can do that.

 It goes without saying they could  sell these s9's at 800 usd  and the diff can be made to jump from 225 to 250 to 300 to 400.

They have full and total control of the market  in terms of gear and they can dictate which way to play the game.
Slow supply high price is what I prefer them to do.
My cheap power has about 15kwatt cap. So high priced s9's work for me.
As an aside it also helps my in house gpu miners.

There is a downside to flooding market with cheap s9's  it drives up their cost of self mining.

Let pick a ph for bitmaintech self mining 120ph of s'9s at 3 cent power .

so look what happens if bitmaintech keeps growth at 8% and at 3%

on day 380 at 8% profit is    427,000
on day 380 at 3% profit is 1,255,000

they need new gear if growth is 8%  and power is 3 cents.

they need not switch out gear if growth is 3% and power is 3 cents.

they control diff growth  right now since they can sell cheaper.

but they have 0 need to sell cheap.

they are far far far far better off with high price.

and if they give the one year warranty they can sell at high price.

if you look you will see I used 500 as the price for an s9 since I think they can build one and install it in their mines for 500.

That's exactly the point I made in the R4 thread. How can it be designed and aimed at the "home miner" when the price was near enough an S9. It would've made more sense to buy an S9 and underclock it but still have the option to run it higher if electricity costs allowed.

Anyway I digress from this thread. The new Batch 14 S9 is $7 cheaper than the R4 was on sale for.

What they should do is drop the price AND offer a 1 year warranty.

Somehow I think they have been caught short with the R4, I think it cost more to develop and they have made short runs of them and are surprised at the lack of interest, I think they are pulling them off the site and putting them back up as and when they think they might sell a few but its not been the hot seller they hoped.

Hopefully this is not wishful thinking on my part and they will wake up, smell the coffee and offer the R4 for below $800 and the S9 for below $1000

3 cent power in my area is shady. included with my 3 cent power is a kw demand charge. In the summer it's $18.00 per kw and winter is $14.00. Long story short my 3 cent power is really closer to six and I'm not saving much money.

phillip -

While I would normally agree with that assessment, the problem is Bitmain can drop the floor out of the market any time and sell the miners for $500 each, then the resulting flood of new hashpower and a few 12% jumps tend to kill that 3-4% average.

See:  Avalon Classic Batch 3, S7 Batch 1/2/3/4, etc

The btc  game has become a game of what do you pay for power?

A new s9 at 1540 + 60 to ship is 1600 usd if you are blessed with 3 cent power

and you can get 12.93th using 1400 watts

you will earn 500 usd in 1 one year with the machine still in hand.

that is a good deal if you have a good warranty.

look at projections for 4% growth and 3% growth  in both cases if you have 3 cent power  you make good money in a year.

name me any investment that returns the numbers below.

so the current 12.93  machine is priced well if it has a 1 year warranty. it is underpriced if it has a 1 year warranty.

So back to my argument they should jack price by 100-200 bucks and give the one year warranty.

ANTMINER S9-B14, 11.85TH/s is now sold out.
edit: now for sale again
edit2: now sold out again
edit3: now for sale again, it is going back and forth

I'm all for extending the warranty, but raising the price is foolish. Their margins probably already allow them to replace every part of every sold miner and still draw a slight profit. With the prices they've got now, we're subsidizing the miners in their own megafarms - we're already paying them hand over fist to screw us in every way possible. The current price might be justifiable if it had a year warranty on it, assuming the warranty counted for anything and they didn't work so hard to deny every rational claim.

Not an option  it won't be good for them in the long run.

They need to raise the price on the s-9 and make the warranty a full year.

BTC is asic bound and low cost power makes you a winner.  that was true with the s-7

it is not true with the s-9  simply because the smaller size chip has a bigger fail rate.

I would max my low cost power solar array today with 4 more s-9's  if I got a 1 year warranty.


You are correct about alt coins.  My summer power rate is 18 cents  and I mine eth coins  I spent 585 for entire home power bill  in August

I earned 1000 in Eth.   About 385-415  of the power bill was my coins.  so I cleared 575-615 mining eth

Yup- I'm testing an x11 rig  right now. Wayyyy more profitable than any sha256 rig.

For quick comparison: I run my Bitmains and Avalons at the lowest cost host site available world wide.....while I'm running my X11 on high cost power at home. The income per "unit of energy used" are much better on my x11 rig at home. Pretty much a "no brainer".
In fact the net profit per day on my X11 rig is very good compared to my S7s and A6s. So buying a an S9 is not on my radar ...unless the S9 is lower than $500 USD and I don't have to buy a PSU to run it.

So what will Bitmain do when the demand for its high cost rigs dried up? They will build other algo rigs. Remember they were going to build a Scrypt rig until it became unwise/unprofitable to do so. Why was it unprofitable to for them to build  Scrypt rig? Well, the earlier Scrypt rigs ( Titans, Alchemist etc.) drove up Scrypt difficulty and the demand for new scrypt rigs pertty much stopped.

So Bitmain has two options:

1. lower the price on their sha 256 rigs, or

2.  get in on other algo rigs asap before their competitors seize that market completely. Maybe its too late for them to do that late already?


BTW: Why do you think certain people that were key to BTC development moved over to other algos like ETH hash? For example: Gavin Anderson comes to mind. Ponder that for a bit.

the 12.93's were 200$ more then the 11.85's

Well the S7's have a better reliability track record at this point.  The S9's use less power though.

I do the same thing and run three or four PC and mine XMR it's holding but price is dropping , i just won't mine it , when it gets to low . saving for two x11 miners , dash is holding around 12.84 s a coin , xmr goes up and down a lot but holding at 10 dollars and eth is around 11 bucks . it all add up and not to bad to mine this way, i like Mining btc but the gear cost to much etc .I have some older btc gear I use from time to time and about 178 MH in script miners, i got a really good deal on a Alchemist 256 that had a bad controller which was no issue . it had one board also . the other seven boards work, i dropped one and messed it up beyond repair and donated one to some one to tech schools with. so i have five boards and one Gridseed 25 MH miner not the little two blade one .a Avalon 6, may try to buy another one,after i get one or two more amd 470 or 480 depends on cash when i buy them .a S1 S3  C1 and A4.1 that set all work the S3 has 2 bad chips . the other miners work like they should.

How much were the 12.93's going for ?

Looks like S9-B14 11.85 TH/s is currently in stock and ready for purchase, im holding out for the 12.93 TH/s to come back in stock.

greetings, have a S9 would be better to have 2 S7 ? I doubt that since I 'm new mining

thanks for showing me this. On freq 600 mines are running on 98-102 and I think this is bit high, I left them on freq 300 which gives avarage temperature 80-87. I need to work on cooling system for mining room I guess.
