LOL BTC3.2 for something that will never mine half that.
If you had %100 free electricity you could never ever ever come close to breaking even on this.
Except that we don't live in a static world. Difficulty will decrease, price will rise, etc. I've never regretted buying in early in the past, and expect this year to be no different. wat? WTF does difficulty or price have to do with anything? If you have BTC3.2 and spend it on one of these miners you are turning BTC3.2 into some amount LESS than BTC3.2. CASE CLOSED. You cannot justify it by talking about difficulty or price or any other random event that have zero bearing on the math. Buying one of these miners takes an amount of bitcoin and turns it into LESS bitcoin than what you started with. WAKE UP PEOPLE. lets see your math. with 3%/jump difficulty rise (its a bit low to adjust for the fact we might see an initial 10-20% drop due to the halving) and power cost of $0.07/kwh it will take a little over two years to break even, and unless <11nm is produced by then the miner will be competitive with the newest-gen until ~2020, where difficulty will likely become fairly stable, mined by anyone paying <$0.06/kwh (all-in: power, rent,wages,etc). Any shift in price will likely have a similar equilibrium effect on hashrate/difficulty. 3.2BTC/13TH is a bad price at >2yrs breakeven. 2.8BTC/12TH is slightly more sensible (a bit less than 2yrs breakeven), but still high. Its likely we see prices fall further if/when a competitor gets to market and bitmain starts building more than they can sell. But if you had free power, both units could pay for themselves within a year, and produce over a bitcoin in profit during the second year. tldr; if you pay <$0.05/kwh its arguably worth it. If you pay <$0.03/kwh you'd be silly not to be mining (perhaps with an S7)

My S7s still did not earn the number of btc I paid for them, but it is getting close. people are upset when this is mentioned, but hobbyists in part moved to the 'other' coin, where mining is not producing this much noise. if your miner is in hosting, there is no 'connection' to it and almost no tinkering, making it less of a hobby, really.

My small DIY stack of S1 units at home at one point made up something like 0.0003% of the network and did quite well for themselves even at $0.12/kwh each generation since has been geared towards power-and-ignore systems that you need dozens of, and cheap electricity for, to make much return. But with that has come the concept that mining hardware is a 2-4 year investment now that we have 14nm and underwent the halving. the easy money is gone

I do not understand either. I have tried to picture multiple scenarios but none of them makes buying an S9 the wise move at these prices. They literally need to cut the price of the next batch in 1/2 for it to be at all even possible to imagine breaking even. Seeing how happy people are to be parted with their BTC in this thread it is apparent that mining is becoming a hobby and a form of nerd entertainment. It definitely is not profitable or even potentially profitable for anyone investing BTC at these prices.
Is investing in "penny stocks" a hobby? Don't think so. Mentality is likely similar. Nobody is buying with a ROI hope at Today's prices, they are hoping the price rises. You don't buy a $5 stock hoping it goes to $6, you hope it goes to $50. Same thing here. Yes, with BTC, there is the alternative of just buying the coin itself, but that is not nearly as much fun. Its a paper transaction vs. having something you can see (and hear!). Fun? Pissing money out the window? Buy and hold. The end.

Buying one of these miners takes an amount of bitcoin and turns it into LESS bitcoin than what you started with. WAKE UP PEOPLE. wrong some of the time. look at the case below it is all about price and diff and show that the two combined has meaning huge meaning . 2000 usd in bank I buy 3.2 coins as I believe you. coins tank to 200 usd . still have my 3.2 coins they stay tanks for a year. due to tank in price diff drops a lot an in the next year I mine 8 coins. so 1 year later my 3.2 coins purchased for 2000 since price stays tanked at 200 a coin buy and hold I have 3.2 x 200 = 640 in fiat or 3.2 coins. vs my investment in a miner which cost has earned 8 coins. so 8 x 200 = 1600 usd and I have the miner. and I can show you this can happen: start on sept 26 2014 and go to nov 23 2015 that is a 422 day time frame with 32 adjustments we did about 2.3% So if we do 2.3% for the next 20 to 32 jumps you would be wrong if price drops from 640 to 350.

WAKE UP PEOPLE. wrong some of the time. 2000 usd in bank I buy 3.2 coins as I believe you. coins tank to 200 usd . still have my 3.2 coins they stay tanks for a year. due to tank in price diff drops a lot an in the next year I mine 8 coins. so 1 year later my 3.2 coins purchased for 2000 since price stays tanked at 200 a coin buy and hold I have 3.2 x 200 = 640 in fiat or 3.2 coins. vs my investment in a miner which cost has earned 8 coins. so 8 x 200 = 1600 usd and I have the miner. and I can show you this can happen: start on sept 26 2014 and go to nov 24 2015 Nov 24 2015 72,722,780,643 10.44% 520,569,941 GH/s Nov 11 2015 65,848,255,180 5.77% 471,360,171 GH/s Oct 29 2015 62,253,982,450 2.25% 445,631,364 GH/s Oct 15 2015 60,883,825,480 0.12% 435,823,399 GH/s Oct 01 2015 60,813,224,039 2.49% 435,318,014 GH/s Sep 17 2015 59,335,351,234 4.17% 424,738,988 GH/s Sep 04 2015 56,957,648,455 4.98% 407,718,729 GH/s Aug 22 2015 54,256,630,328 2.95% 388,384,088 GH/s Aug 08 2015 52,699,842,409 0.81% 377,240,166 GH/s Jul 25 2015 52,278,304,846 2.35% 374,222,683 GH/s Jul 11 2015 51,076,366,303 3.39% 365,618,871 GH/s Jun 28 2015 49,402,014,931 -0.58% 353,633,397 GH/s Jun 14 2015 49,692,386,355 4.42% 355,711,957 GH/s May 31 2015 47,589,591,154 -2.50% 340,659,563 GH/s May 17 2015 48,807,487,245 2.44% 349,377,603 GH/s May 03 2015 47,643,398,018 0.07% 341,044,727 GH/s Apr 19 2015 47,610,564,513 -3.71% 340,809,696 GH/s Apr 05 2015 49,446,390,688 5.84% 353,951,052 GH/s Mar 22 2015 46,717,549,645 -1.50% 334,417,246 GH/s Mar 08 2015 47,427,554,951 1.59% 339,499,662 GH/s Feb 22 2015 46,684,376,317 5.01% 334,179,783 GH/s Feb 09 2015 44,455,415,962 7.71% 318,224,263 GH/s Jan 27 2015 41,272,873,895 -6.14% 295,442,739 GH/s Jan 12 2015 43,971,662,056 8.20% 314,761,417 GH/s Dec 30 2014 40,640,955,017 3.00% 290,919,288 GH/s Dec 17 2014 39,457,671,307 -1.37% 282,449,013 GH/s Dec 02 2014 40,007,470,271 -0.73% 286,384,627 GH/s Nov 18 2014 40,300,030,328 1.76% 288,478,854 GH/s Nov 05 2014 39,603,666,252 10.05% 283,494,086 GH/s Oct 23 2014 35,985,640,265 2.81% 257,595,247 GH/s Oct 09 2014 35,002,482,026 0.98% 250,557,526 GH/s Sep 25 2014 34,661,425,924 16.20% 248,116,151 GH/s Do people really not have anything better to do than go around telling people that they're idiots for mining? As though someone who does not own miners, and thinks it's a stupid idea, has any opinion worth hearing. I bought miners, which are inflationary as there are always more being made, to mine a deflationary currency. You haven't for a fraction of a second considered every scenario possible in this situation, and yes, it involves gambling on the future. Fact: Purchasing miners has been a win for me so far, and the future looks sunny, I am under no obligation to "show the proof". I could hardly care less what your (or pretty much anyone's) opinion on my mining operation is.

wrong some of the time.
look at the case below it is all about price and diff and show that the two combined has meaning huge meaning .
2000 usd in bank I buy 3.2 coins as I believe you.
coins tank to 200 usd . still have my 3.2 coins they stay tanks for a year.
due to tank in price diff drops a lot an in the next year I mine 8 coins.
so 1 year later my 3.2 coins purchased for 2000 since price stays tanked at 200 a coin buy and hold I have 3.2 x 200 = 640 in fiat or 3.2 coins.
vs my investment in a miner which cost has earned 8 coins. so 8 x 200 = 1600 usd and I have the miner.
and I can show you this can happen: start on sept 26 2014 and go to nov 23 2015
that is a 422 day time frame with 32 adjustments we did about 2.3% So if we do 2.3% for the next 20 to 32 jumps you would be wrong if price drops from 640 to 350.

I would almost never tell someone not to mine, since it is fun as a hobby, but I have a counterpoint to your scenario. Say, I took $2080 for a miner and converted it to buying $40 btc worth each week-easily done. if btc goes up, i am ahead (in $$ profit), this is clear. if btc goes down, then i will get an average weekly price over the year. If, for example, BTC average price over next 12 mo is $400, i will be able to buy approx 5.2 BTC without any mining costs. At $400 mining cost in hosting (at 9c) would be $95 vs $245 production with current difficulty throughout a year. $150/mo profit. $150x12=1800, which is 4.5 BTC vs 5.2 BTC in alternative scenario. Close, but no cigar. That said, I almost bought b3, but by the time btc reached the wallet (non coinbase), it was gone, which shows that even when I thought that it was not optimal, I was temped (when it was 2.6 btc, admittedly).

just a thought but my knowledge is limited compared to most here. If you ran three miner off one psu.. what if you had voltage drop which would increase the amperage running thru the miner .. could be this scenario. http://ask.metafilter.com/244859/Voltage-drop-amperage-increase"If you have switch mode power supplies (e.g. practically all IT equipment these days) then when the voltage drops they will pull more current to keep up their output. If your voltage sags a bit because of too high a demand then they all pull more current and you're boned." Best regards d57heinz Exactly what I was trying to point out in the first place in different words. Its so good to see A person out here that knows what he is doing. its feeble-minded people that dont even have common sense and think they know it all is the ones I hate. but I know what I have and hold and is recognized by the NEW YORK STATE BOARD OF REGENTS. usa. and other stuff which i will not mention. Don't forget to polish your "clueless dickhead of the year" trophy. It's more widely recognized than the New York State board of regents. Though I'm sure they would be honoured that someone of your intellectual capacity and attention to grammar is publicly representing their fine organization.

Best regards d57heinz What they were referring to in that link is on the AC side of things (hence referring to the blowing of the AC fuses). The reasoning being since the current demanded on the DC side of the power supplies stayed constant, but the voltage provided on the AC side was effectively decreased, the result was an increase of amperage to maintain the said output. My problem did not happen on the AC circuit, but on the DC circuit (one miner) shorting and burning. When AC voltage decreases, current on that circuit increases to maintain DC output. By that reasoning if AC voltage dropped low enough and resulting amperage increased, the circuit breaker on the PDU (read: AC side) would have tripped. However, as alluded to previously, if DC voltage mysteriously would have decreased due to these circumstances (which it wouldn't), the current through the miner would have also decreased (following the same logic used for under-volting string miners to increase efficiency) and not the opposite catastrophic event.

Am I calculating this right for a single S9 miner....
$2075 for an S9
12.9TH hashrate using 1350W
Electric rate 13.111 cents per KWh in southeast Wisconsin
ROI for just the miner 365 days ( not including climate control electrical costs )
... ...... ......... ............ If its a year til ROI, and it takes Bitmain LESS THAN a year to come out with a new model ( The time the S7 hit the market to the time the S9 was being sold was less than a year) ... individuals and farms will not be profitable at all .... the death of bitcoin mining it looks like... unless you have solar or renewable energy.

New machines won't be coming out for another 2 years. There will be no more than 20% improvement on efficiency on the current machines. You have time to profit.

Speculation of a 10nm chip is 14-18 months. But that is just rumor and could be completely wrong.

That doesn't mean they can't optimise the 16nm process somewhat. Bitmain put out, what, two? 28nm chips that each improved on the previous process. I'm sure we will see a chip revision with new hardware coming out sometime... how soon is the real question

Finksy is not the first person on the forum to have a bitmain product melt down. Oregon Mines will not even allow you to run a bitmain psu at their facility. Shit happens
As far as all the ROI talk goes... if you can't roi then great do not buy a miner. If you want to support the network, then maybe you should consider buying a miner. Some of us spend money to run a full node which does not return any money. It is not always about "getting rich"
If you bought a S5 that roi at an average of $250/btc which is now over $600/coin then sold that s5 last winter for more than you paid brand new, used that money towards an S7 that roi eaily then sold the s7 at $400-$500 each to put towards an s9, I do not see how you cant return on your money.
Buying/holding coins may be easier and make more sense but that is pretty boring. That also requires all the money upfront to buy. As I explained above, mining is a cycle of buying equipment, mining, selling old gear after 9-12 months, upgrading, repeat.

Voltage drop could have also occurred on the dc side. I see it quite nicely on all my psu under load. Maybe is just I don't have that great psu. But as I get closer to maxing out psu it will start to sag the voltage. I know with your responses you won't get any help here. And I don't know enough yet about this subject. Maybe the switching supplies don't have this phenomenon as does the typical gamers psu. I know a few of my gpu if I use the rose will psu I have they over heat. When I check gpu z it showed only 11.38 volts going to card under load. Was just a thought anyway. Good luck
Best regards D57heinz
Edit what does stand out to me. Is the fact bitmain added this exact failure to their list of non warrantied items. Burnt hash board. So maybe they built them with just good enough traces between circuits to get by with minimal voltage if you drop below 11.6v then game over. Regardless I feel they have no way of knowing what the issue was for certain to deny his warranty. Unless they have knowledge of this problem and know for certain it was psu voltage drop that causes this. Scary to think. My power does a lot of funny stuff when storms slam thru.

Hi to everybody. I have an s9 antminer 12.93 th/s. Today the yield moved from 0.03 evere 24 hours to 0.018. What s is going on? Difficult increase?? I cannot check... i am abroad. Or maybe my 3g data plan is suffering.? Which one is your actual yield? From the dashboard of antpool i can see that they miner is on and the hashrate looks ok.
ummmm The block reward just halved
