They are using S2 to heat up the spa? |

Thanks windpath. I'll give them a try once my Batch1 order arrives.
I hope they'll start shipping today or tomorrow.
I thought that Bitmain commented that they will start shipping on 14th. |

I said the evga was best. its biggest flaw is it is a little loud .
I have a seasonic 1200 platinum it is better if you want a quiet psu.
but it is 290 usd.
I can't find a good sale .
I use the seasonic on 11 gridseed blades pulls 900 watts for the 11 blades. the nice thing about it is 8 separate pcie cables
while the evga uses 6 pcie cables.
but 290 vs 153 or 170 and the evga wins out.
I assume it would be a bit quieter when not running full out - and it wouldn't be with the 2 S3s overclocked. Bitmain's original specs for the S3 were 504GH/s at 390W from the wall. Latest I read was that maximum overclocked draw was 0.981W/GH/s, so total draw would be ~1100 watts from the PSU, which might get the fans spinning. In any case... I've got an SP10, so I'm very well acquainted with loud fans  yeah that puppy is very loud. I was running 7 s-1's clocked to 393 freq house was hot and fans were really loud. And the wife was pissed off at the noise. Oh I hear it all the time... the first time I plugged that SP10 in, she came in from outside on the porch and said, "What the hell is that noise?" When I explained it was my new miner she said, "You have got to be kidding me. There's no way I'm listening to that damn screeching." So, I tweaked the settings and put it in a corner in the basement. Every day she'll still throw a comment out about not being able to hear me over the noise.  Oh, the famous wife or GF factor. If BTC goes to 10K, the first question would be-why you had ONLY seven? I agree that noise, especially noise with changing tonalities (like S1 does when it accelerates) is a major decision maker. If S3 is noisy, I will have to sell at least some. |

Regarding refunds.
I think that most people went into ordering Neptune because we expected it in March, maybe April, at least I was.
Then in January-February it slipped out that development is not that far off from the drawing board and datorhall pictures were posted, upsetting some.
This caused the first wave of refunds.
Second wave was caused by the depressed price of BTC where it became obvious that it would be difficult to make any money at those prices.
Perhaps, to KnC management it looked like a betrayal and sophisticated hedging strategies, but I think it was quite simple-just math.
However, going forward, i don't think that pre-ordering money collection would work to the same level of success as with Neptune. There are too many entrenched players with a low cost base. The only thing that could re-invigorate the pre-orders is a spike in BTC price.

this SP30 is a joke !At this price it would be good if it's delivered right now,but when this sp30 comes out in SEPTEMBER it will be useless at this price !
Yea, I want to support Spondoolie and the community and keep myself in the game, but at that current price with a $300 shipping charge the most I could ever make would maybe be $2500-$3200. So, for something that cost me $5395 and only get the most $3200 out of it doesn't seem like a good investment. And I'm working with the current numbers, the September numbers would even be worse. I'm trying to keep myself in the game, and I'd really hate to buy a few Antminer S3's, but their so damn cheap it is hard to say no. I'd rather use a Spondoolie product for good support and a quality product but maybe this go around I'll just stick to buying bitcoin out right from now on and not have to worry about hardware. Apparently it seems everyone in the world is putting up their own data center these days. In my opinion, the main problem and concern we ALL should be worried about is power. Opentoe, please do me the favor of replying to my question with your (approximate) percentage gains from your calculations. Just curious. Regards, ~Blaise Obviously I used an online calculator and it came to about %66. I used the Tradeblock site, which isn't set in stone with the output numbers, but I would definitely say they are a good approximate. Here is what I input for one SP30 starting in September. https://tradeblock.com/mining/a/a45142e2e9Maximum profit only indicates $3630, and yea, I was high with the difficulty increase cause I'd rather have worse case numbers to make a decision on. I think if I spend over $5k on a mining rig and then have to spend $300/month to co-locate I'd want a better reward than $3k-$4k. For 6TH/s in September I think $5395 is too much right now, that's all. I'm hoping all the numbers are correct. The reason I kept the diff at 20 is because at that time there will probably be a slew of KNC Neptunes online, thousands of Antminer S3's and, another one called Rockminer?, and then of course Spondoolie's. That's a huge dent onto the network, and if you adjust that difficulty setting on that page it does change your max profit considerably. The lowest change in 4 months has been %10.66. Jun 29 2014 16,818,461,371 24.93% 120,391,236 GH/s Jun 18 2014 13,462,580,115 14.51% 96,368,902 GH/s Jun 05 2014 11,756,551,917 12.44% 84,156,677 GH/s May 24 2014 10,455,720,138 18.10% 74,844,960 GH/s May 12 2014 8,853,416,309 10.66% 63,375,223 GH/s Apr 29 2014 8,000,872,136 14.64% 57,272,474 GH/s Apr 17 2014 6,978,842,650 14.04% 49,956,502 GH/s Apr 05 2014 6,119,726,089 22.23% 43,806,706 GH/s I've never been a risky person, so I hesitate, and sometimes I lose out. The best thing I ever did was buy a KNC Saturn and then bought 4 upgrade modules. That little guy is still chugging along. I think if my house had more electrical resources and didn't have to worry about cooling I'd have mining rigs all over the place. It is addicting. whatever you linked to on traderblock assumes 20% increase in a MONTH, not a cycle. 20% is definitely on a lower side, but possible in 6mo I would use 30%/mo. In this case-about breakeven in april 15. here is is: https://tradeblock.com/mining/a/5d5e92893dbottom line: profit is possible ONLY if difficulty stagnates to below 30%/mo AND bitcoin increases in price. |

I should soon have ANTMiner S3.
very profitable.
Not sure I would claim it to very profitable, will barely ROI. Bitcoin investment is possibly a better use of your fiat money. But hey, I still have 8 x s3's on order , so i'll shut up :s Just make sure that your digs can handle ~3kwh extra. I know that my comfortable limit (at least in summer) is ~2.3-2.4kwh extra heat and this is pushing it, which equals one S2 and 3 S3 However, I greedily ordered 6 S3 and now contemplate what to do as I don't want to sell the S2. Selling the rest on ebay looks like a waste of time because of a small premium. |

When is somebody going to make a magical money printing machine that is plug and play? :/
Lol the Antminers are basically plug and play (It cannot get much easier) Yeah, but the whole IP thing, mining configuration, admin password, and the power plug. So untoasterish. I can start a service "mining for dummies" not meant as an insult but to mock the book series. You call us up give us your pool info we config and ship it to you plug and play ready all you do is plug in power and data and off you go  for a low low fee of 0.3BTC? Could be popular... |

enermax platinum 1600 gold, can run 3 unites S3 at the same time . (runing OC)
isn't it rated at 1350W? $295? Evga or corsair looks like a better deal (both ~$75-76/S3 when overclocked) |

What is a noise level of AntMiner S2 1Th/s? 80Db?
Less than that. It depends on your ambient temp. Highest I've recorded was 70dB and that was in 30'C or so ambient. re db- I have a very quiet S2 from the recent batch that was shipped 6/26. Room temperature: 28.4oC/83oF At 1m distance, it is just 62 dB, and if you get as close to the fans as possible-66-67 dB. I know that some reported different numbers-but this is what I got with dB Pro app on iPhone. |

I have several S2's however anytime I have a power outage, or I need to move one I have to reset them up.
Any Ideas about what I am missing?
Jerry
make sure that you are running the system from 6/19/14 and NOT 4/10/14. If you are still on 4/10, download 6/19 to a laptop, then use update function on the "system" pan in antminer S2 to browse for it, then update. The "wheel" will be turning forever, but you have to wait just few min (I waited five from the abundance of caution), then simply close browser window and power cycle the miner (PSU OFF, wait 20 sec, back ON). It helped for my s2. |

Shipping starts July 10 not delivery. And it isn't guaranteed to start on the 10th.
+ There is no way, that I am aware of, to change the order with Bitmaintech so whoever buys it from you has to wait for it to be delivered to you and then have you re-ship it to them. This will result in an additional delay which is the reason you are not getting any offers @ 1.5. There will be a minimum 48hr delay in someone getting these two miners, and it could be longer than that.
I also think it might help if you screen capture your order and put it in the thread.
1. you can change the address 2. it's not like you can get batch 1 if you order today, so this logic is meaningless. batch one order will be in your hands at least 3-5 days earlier than batch 3. |

Hey there,
If you include PSU than 0.25 + shipping is ok
if you want with CX500m PSU-total 0.31BTC plus shipping. Ground in US should be ~$15 for miner and about the same for PSU, but could be a little bit less for PSU-I will have to find out. Are you in Tbilisi? postage could be expensive. yeas but I want items to be shipped in Minnesota. How much will be the total cost with everything included ? Ok, i found out the shipping cost. Total for S1 plus Corsair CX500M plus shipping is 0.36BTC If you agree, let me know, I will pm my wallet address Payment first, then shipment today |

"...and sold all of my coins in my wallet at $6 a piece"
I had ~100 BTC that I sold around $7.00, so I know something about how it feels. The "rally" from $1.9996 to ~$7 took so long and the price seemed pretty high at the time.
Ehhh.... i sold over 1k btc when it was ~$9 I dont cry like a bitch like some of the "hero members" on here tho. I'm actually happy for bitcoin and community. Remember, the early TXs are needed for btc to grow. I know that it would not sound like much, but I assume that you are young. Programming or building businesses in bitcoin are a great venue for you to recover 500 BTC and then some. After all, 500BTC is "just" 300K, which is what some very good programmers are being paid in a year or even less. |

You are fighting the wrong battle. I personally don't give a shit what anyone calls it as long at they do not criminalize or regulate into the oblivion the ability to cryptographically transfer digital tokens of value from one individual to another.
well, the fact that opinions differ from yours does not mean that they are wrong Virtual has completely different meaning from digital or crypto. Virtual currencies are game tokens typically Exact wording is very important I consider using the term "virtual currency" in the case of bitcoin inadequate/imprecise/demeaning/jarring etc "Virtual" strongly suggests that it is NOT real or at least not material. But, it's just for me, you might have a totally different view. |

In January and February I had s1s that were roi positive too.
But now they are not because the difficulty has gone up too much.
My point is it mines less now because the difficulty is 16.8 b not 4.3 b was in March. Its hard to pay more than $80 for a s1 now if it can only mine about .13 btc. I would rather buy .13 btc on Coinbase than pay more for a s1.
It will have a value as a heater starting in October. Which heater "almost" pays for itself plus reduce the gas bill? Yes this was the good idea they had earlier. Or maybe some people can sneak into the office and use their electricity. I just made a heater savings calculation My house used 232 CCF of nat gas for ~$200 in january 2014 103100 btu/CCF Antminer (almost all heat) at 190GH uses~400W=1364.85btu/h 1364.85X24x30.5 (average days in a mo)=999070 btu hence, one antminer saves 9.69 CCF in heating/mo or $8.35mo, so 10 antminers (or equivalent kw) would save ~40% of the gas bill. Not bad. even better if you pay higher nat gas price (i see that it is ~30% higher in new England) |

They can mine about .185 btc left with .08 cents electricity in China.
.08 btc with .16 electricity like most of USA.
.01 btc with .30 electricity like alot of Europe.
even mining.thegenesisblock gives better numbers: $220 in revenue in 3 mo with ~$90 in expenses after that-pencil mod and another month of profitability. total profit $145 or 0.228 BTC assumed $0.12/kwh in electricity (this is what i pay in US) and $634/BTC Your .12 electricity and 634 btc price will mine .129 btc lifetime. this can't be right, unless you are subtracting the electricity cost. all calculators show ~0.3BTC total (BEFORE subtracting the electricity cost). if you are assuming 18% jump every 10 days-it is simply NOT going to happen, unless hardware market goes truly crazy. YES is after electric cost. You have to add this. If someone has a BFL minirig, they can claim mines at 500gh, but uses 2400 watts! is crazy, is as useless as BFL Jalepeno, Single 30 0r 60, ASM Cube. At 16.8 B difficulty: July 7-11 16.8 b diff 180gh at 370 watts mines .0054 btc per day x 5 days. At $632 per btc is $2.40 per day - $1.07 = $2.33 per day profit. This is $11.65 July 12-23 19.8 b diff July 24-Aug 5 23.4 b diff Aug 6- Aug 18 27.6 b diff Aug 19- Aug 31 32.6 b diff Sept 1 - Sept 13 38.5 b diff Sept 14 - Sept 26 45.4 b diff Sept 27 - Oct 9 53.6 b diff This is the way to calculate it, by each day within each difficulty period. since you assume 18% difficulty, it is going to be incorrect. According to all calculators in march of 2014, antminer S1 could barely brake even, but it had a 25% ROI in BTC plus residual value that exceeded electricity+PSU. I am going to revisit this post on october 6. My prediction diff less than 46b. If it is at 54b, ALL mining is useless. |
