Hahhahahaha! $2100. BITMAIN must be feeling like top of the world right now to quote a price like this.

Well it all looks good on the www.tradeblock.com calculator on all this 7 months to ROI etc  etc

er WAIT....THE HAVLING IS COMING IN 1 MONTH

oops...don't look so goo now (*unless counting on a corresponding btc price rise)

so er NOPE not with a 90 day warranty ..halving coming up and 14c kwh ..I'll stick to the KNC Titans....(assuming I ever find any for sale again)

Nice Specs, Congratulations Bitmain!

Like others, I will just wait until halving, and then reconsider.

[abokhalel2]

The s9 seems over priced. To put this into perspective, let us compare S7 with S9. let say the aim is 14TH
1 S9 = $2100
1 Power Supply (from Bitmain) = $140
Shipping to the US (Fedex) = $75
Total = $2315

To get the same hash rate with S7, we need 3 S7s, 4.73 x 3 = 14.2TH
3 S7s = $1320 ($420 each)
3 power supplies = $420 ($140 each)
Shipping to the US = $140
Total = $1880

The difference is $435. If you think the space and efficiency worth the difference, go ahead and buy it. If not, (let say, you have a very cheap electricity, and plenty of space), S7 is a better option. If you ask me, I would say don't buy any of them. just wait until halving, the price will be more reasonable, and you can evaluate your investment better!

me too...

Holy Moses, they did it again.
Only problem is ROI with that price tag. We are looking at more than 140 days.

I have the same thoughts. The power consumption and the efficiency is very good. But the price is too high.

crazy be the ones who buy the S9 at this price with halving coming in 1 month!
it would barely ROI without the halving ...

1 used KNC Titan mining at 325mh (less the 350mh max possible w/all working dies) at 1,250 watts and 14c kwh and $4.57 LTC gets you

using this 'open' calculator (you don't have to be part of litecoinpool to use it)

www.litecoinpool.calc

30 days   102.08649902 LTC   466.54 USD Total   126.00 USD Electric   340.54 USD  Profit after Electric

and that is for a USED machine. Converted to BTC that is at current $533 usd that is 0.6389118198874296 btc per month AFTER ELECTRIC.

Not bad for 20 month machines out there in some cases. NOT sure how this would figure on the price to buy a used Titan (if you can find one ..ie Unicorn Hunt)

but much better then this S9 especially at my 14c kwh rate (shudder). Also this depends on the speed of your used titan depending on the hash speed you can get.

So not only does it not work as well as 3 S7's it sure does not work with a Titan unit ..even used at 2.5k to 3k imho....just saying

Guys I have some questions, halving comes for about 40 days. Is that mean, that if we say that difficult not going up and If I earn currently 500 usd monthly, earnings will be 250 usd after halving? Or that is not exact situation? I ask this because when LTC halved earnings wasn't halved, they reduced for about 25%...

I think they understand the pricing pretty well here.  The price of electricity has been established around $60/month.  Considering 2 less minor this bring the price to 3~4 months.  Everything is set for a ROI of around 3~4 months from now.  But one thing is for certain, once these things get out into the public we can expect to see difficultly to start increasing by 20% again.  I was really hoping with halving people were going to start turning their miners off and difficulty would stabilize, but it looks like technology will continue to push difficulty up even after halving.

It really depends on what you think will happen and nobody knows until afterwards.  I thought difficulty would decrease or at least stabilized after halving since rewards would be halved and people would start to shut miners down.  But if more efficient miners come out it looks like difficulty will continue to push up.

To mod: sorry I know this goes in the speculation forum.

Yes. The earning will be $250 after the halving. I also think the difficulty will keep on rising after the halving due to the new S9.

Nice Specs, Congratulations Bitmain. I don't think it will reach ROI at this price.
Like others, I will just wait until halving, and then reconsider.

after the halving, the price of this unit will be around $ 1000

i agree with you, just wait and then reconsider, but even with a price of $1000 i am not sure it will roi after halving.

The situation is quite similar to that we experienced september 2015  when S7 arrived, (halving perspective excluded).

I 'm curious to know if a lot of people who pay their electricity >= $ 0.1 / KWh won something with their S7 ?

[Soros Shorts]

okay I did a second order paid it  and it is marked not paid expired.

first order is marked paid.

so this does happen and it is late in China  but  I hope they fix this sooner rather then later.

This happened to me.  I paid within 7 minutes of my order.  It showed expired for about 3 hours.  During that time I flamed them with emails and support tickets.  They did not respond to any of those, but I did get a "Paid" email confirmation about 6 hours later.  21:00 GMT.

As of now, I still have a paid order that has been marked as expired for over 12 hours. I am surprised they haven't fixed it during their claimed office hours of 9am-6pm Beijing time.

Yes. I bought many of my S7 with USD .  With VAT 2100-2300 USD

I sold BTC at 475 EURO last month. Do Batch1/3/5 machine earned a profit of 4.5 BTC after electricity ?  Yes.

 I bought my 5x S9 with BTC because I think that the BTC price will fall after halving or before.
S9 miner owners do not need a high BTC price, they require low Bitcoin Difficulty: and Network Hashrate.

To compensate for this I bought  5x S9 with USD from friend's account.

When I put them to work I have to sell my S7, because I have no more power.

It's the greatest machine ever!

[VirosaGITS]

I saw the price, and then i laughed.

You'll get it just in time for the halving, and then you'll be lucky to make 300$ per month with it. 1 Year ROI? No thanks.
