T9 looking like an absolute bargain, im wondering whether these prices may go back up when the BTC prices returns to 15k+?
Thats a huge /when...
But i guess they will sell pretty quick if the ROI gets even better
I bought 20 but it is a weird spot right now to buy, seems like there is gonna be a new miner from Bitmain at any momento, but at the same time from what i have read around the next jump in miners wont be that high maybe 20 th/s not like the S9 vs S7 4th to 13 or 14

Horrible ROI for a miner thats months away from release.
180 mh/s is barely 170$ a month. By the time they release it if prices dont go up that miner will be worthless. But yeah GPU mining is dead thats the cost of 2 rx 580

I just looked online and Bitmain is having a sale on the S9 and T9+. A 14TH S9 with power supply is $1864 but you can buy T9+ 10.5T with power supply for $855. You could buy 2 T9+ for $1710 and have a total of 21 TH/s. I did the calculations with my power cost of $0.064 a kw at the current rate of BTC I would generate about $289.97 profit a month with the 2 T9+'s as opposed to $219.48 a month profit with one S9. I would ROI in about 6 months and even sooner if I got a hold of some good $200 coupons.
Am I missing something? It doesn't seem to make sense to buy an S9 at the current prices.

ROI is beautiful in these T9 and from what i have read they are very reliable, they lowered the price to 755 with PSU. If you have 420$ coupons u cant beat that ROI. My power cost is around 0.05$
Your ROI calculations are off you are not taking into account raising mining difficulty. Also shipping is kinda expensive around 110$ per miner i bet you can find some 420$ coupons for around 50-80$
It makes sense buying a 14th/s S9 if u dont have cheap electricity, they are a lot more efficient...

Buying those 420 coupons ! Seems like somebody at bitmain likes to smoke some weed haha #420
Anybody has any experience doing small orders to avoid paying customs and all that hassle? Also if i use coupons the invoice they send reflects how much i paid or the price without coupons?

Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Getting an S9 is really tempting as far as being a miner is concern. But still consider the operational cost . If electricity is cheap at your location then go for it otherwise it is really hard to attain ROI.
Where you live? I think i live in one of the expensive electricity city in the world and still my ROI is less than year that doesn't sound bad to me because there is no business to give ROI in 1 year or less (Not Talking about ICO or holding Coins) any type of business. Yea, depending on where you live, it ROI can be had for less than a year. Some people want a faster ROI though.
Dude, ROI in less than a year is not guaranteed. U dont understand that difficulty increases as time passes by and new stronger machines may come out later to make yours obsolete. That is the bet. That is why ROI needs to be short. Difficulty does not remain the same throughout. It increases faster than bitcoin price.
ROI is crap im selling my s9's and i pay like 0,005$ kw/h electricity

*** that thing about gpus being more profitable ***
When I first read that a while back I thought it was insane. But my alt coin rig (4 rx 580s, 8gb)
is pulling in .00064576 btc a day on nh. That's the equivalent of adding 8 T/Hs capacity to my ASICs. Now I see what you mean. I paid 269 for 2 and 313 for the other 2, so about 1200, and I just frankensteined them onto my existing gaming pc. Compared to a 6.5 or 9 T ASIC that's far cheaper and more profitable.
I don't think what you said is so crazy anymore.
GPU mining isnt THAT profitable, i built a rig 10 days ago 152 th/s 6 rx580 etc etc 3100$ 200 shipping to my country 3300 im making 360$/month with a coupon i could get an s9 here for a lot less than that and making 400$ a month
And all that is me buying the video cards by myself wich i know most ppl wont know how to do because they sell out in seconds
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
People mining for the last 5 years made a killing because difficulty was low and price was low. So they got more bitcoins even though price was low. Now price is high ($10k vs. below $800 back then) and difficulty even higher. The whole premise behind mining is to accumulate more bitcoins as bitcoin pricing was just secondary to mining. But now you get less and less bitcoins everyday and that's going to continue. If you spend $2600 to get an S9 + PSU running, it's going to take a full year to make 0.41 BTC (2 weeks ago it was 0.47). If you spend the $2600 and buy the BTC instead of the miner, you'll have about 0.25 BTC now. If you mine with the S9 it's going to take over 7.4 months as of TODAY. Depending on the difficulty increases, it's going to take even longer than the projected 7.4 months as the calculator assumes no difficulty increases.
Indeed. But i would buy the miner just for the sake of it. It is a good investment for cash, i believe, if for example you need in the next 3 months a source to take cash for paying the rent.
This is one of the most retarded things i have ever read. The level of stupidity this post shows has no parallel
On topic it is pretty obvious they are dumping their whole stock of S9's. Either a big but in price is coming or a new miner for the same price

Welcome R4 to Bitmain Family.
It seems they are announcing a new machine every week now
http://shop.bitmain.com/antminer_r4_silent_bitcoin_miner_for_home.htm?flag=overview
Marketed as a "silent" miner, to be used at home. From initial specs listed on Bitmain website, I could see 8th/s and 2600w (if I am reading correct). Do you think this could be a game changer? If not, I think we could finally have real home heaters (if not noisy)

It isnt new, the R4 is old AF, they just discontinued them really fast, they broke too much
Re: Bitmain Announces the Antminer R4 and APW5 Power Supply, Designed for Silence
They're going to sell these again? I hope they got the horrible failure rate down to normal S9 levels!

Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
if you have free power and nobody has to listen it's awesome.
Even with free power you still have the cost of the money you put in place and your time along with any import fees and rental costs.
As a space heater then it works well at 9500 USD/BTC getting you a small profit of 0.04BTC over the course of 1.5 years of babysitting.
An estimated 0.04BTC over 1.5 years. Damn near nowhere certain.
Also out of curiosity because it's very difficult to read that spreadsheet, does that include the large chunk of money you'll get back when you go to sell and upgrade miners in the future or are you just for some reason assuming that it will be a piece of metal to throw in the garbage?
Great question.
Unfortunately I have not had a request for this. However I can add it.
Like selling and keeping your overhead low and perhaps using these as heating sources in place of conventional heaters.
The reality is you can depreciate the asset over time to get tax savings.
I don't know how accurate it would be because god knows what will happen a few years from now, but you could use the time since the S7 has been released and the percentage that its retail price on Bitmain vs. it's resale price on eBay has declined over that time span and factor that in. It's a lot of money that a lot of people don't consider when they calculate ROI.
S7 still selling for around 700$
In a country like Venezuela electricity is free, a s7 makes more than 100$ a month thats A LOT OF MONEY over there, minimum monthly wage is 5$ believe it or not. So yeah, there is still a market for old miners in some countries. I think in some UAE countries electricity is also free, but i doubt they see it as a business oportunity those guys are swiming in money
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
...and a new Antminer V9 in town!
you get 20T for $1725
but you'll have 5 miner + power supply
you get 20T for $1725
but you'll have 5 miner + power supply
yeah 5000w for 20 TH/s......eff that noise
In Venezuela electricity rates are lower than 0.004$ kw/h, also i know some arab countries have almost free electricity
I can see how this is gonna sell pretty well for some miners
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
I am scared now because I have so many ant-miner S9 yet to be shipped and I want to buy the new one because the S9 will be worthless once the new one is released. Unless they are trying to advantage of the market drop buy selling as much as possible so when the price climbs they just doubled there $$$
S9 on sale for 2 days now the market isnt running to buy new s9's thats a good sign. Also Hashrate has been going down steadily for 3 days.
Price is up
If you can resell your s9's for 1k more than cost, well do it...
Also it is pretty funny how ppl think that moving hash power from China to Canada is so easy, the only way i see big companies like bitmain moving fast to Canada is if they do a joint venture with a canadian mining company. Ppl seem to think somehow that setting up a mining farm is simply moving to a warehouse connect the miners and BOOM DONE, no regulations, nothing HAH... i guess they havent dealt with bureaucracy and all that bs
Sea shipping time, bureaucracy permits etc, hiring new ppl, setting up the whole farm, renting or buying new space, etc etc etc. For examply i know for a fact that a S9 is CSA certified (Canadian Standards association) but i doubt the other equipment they use in China is CSA certified
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
A 1% increase every 18 days, you guys are kidding, right?
2 weeks ago it increased by 16.8%,
2 weeks before that it increased by 15.3%,
2 weeks before that it increased by 3.0%,
2 weeks before that it increased by 17.7%
2 weeks before that it increased by 18.1%
In the last year alone, difficulty has increased by 490% (last Feb it was 0.441T, now its 2.6T), and it is now increasing at a rate much faster than that.
So I dont know how you guys justify the numbers above.
And whats this about difficulty will level out? Why would you think that?
You are aware that in the almost 10 years of bitcoin history, THAT HAS NEVER HAPPENED!
In fact, apart from the odd blip here and there, difficulty has ALWAYS increased and the rate at which it has been growing has ALWAYS been increasing as well.
Just look at the data:
https://data.bitcoinity.org/bitcoin/difficulty/5y?t=l
Saying it will magically start to flatten out is true wishful thinking in my opinion.
Anyway, keep buying those S9s every time Bitmain releases a batch

Learn to read, 5% preset difficulty every 14 days, thats an avg of 11% monthly, the avg was 7% in 2017. Last year there was some big jumps in difficulty too...
And like i told you some posts before i dont know what hashrate chart u are looking at. The one im looking at we are back at hashrate lvls of 15 days ago and it keeps going down.
Also nobody expects difficulty to simply go flat but to go up in lower numbers than it is raising after the whole craze in december
PD: I dont think anybody is discussing with you that selling a s9 for 5k is much better than mining i sold my order of 6 for 4.5k each
Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
Here is a chart that you can use that will help.
I have updated it with Bitmains latest offering of the Antminer S9.
It seems that the network difficulty will be dropping. Perhaps due to BCH taking a little of the mining hardware out of the picture or older hardware being taken offline to to operating costs.
To clarify the chart I have is set to have an increase in difficulty at 1% every 18 days. THIS IS AN ESTIMATE. It may drop % a few times. However I have factored in the average increase over the last two years and even the average from the last year.

Great work, goes to show some naysayers here talking about Avg 15% increases... Some ppl are very naive to think big mining operations will run at a loss based on faith of a bitcoin price increase. Fact is mining will always be profitable, the only way a S9 becomes unprofitable is if something REALLY good is released in the next few months and they flood the market with it.
