Anyone got any ideas? - Just got two hooked up today, one works fine, this one wont start hashing.. A note. Due to lack of PCI-e plugs I have only connected them to two of 4 ports on each S3..  maybe wait longer than 12s...sometimes it starts slow (but not THAT slow, though). check if you pcie connectors are connected well (latched on), they are a little tight to get in properly in some cases. maybe go to <system> and reboot |

So the dilemma compensation wise so far :
1) to order the current 4.5 TH sp 30s at a reduced rate in Sept for your compensation (15% off?)
2)receive cash or btc compensation for your current unit(s) since we paid 4500-5000 and current price is 3900 or so which averages to 15% off say $800
3)wait for the details on compensation for October batches (I would assume maybe 15% -20% off?)
its a tough call another 4.5TH Sept unit at around $3100 is a good deal, but a 5.5 TH unit at the same price even though its a month later is a better deal right ?
what do you all think.
It's only an ok deal if they meet their specs. or not, if Bitfury will continue bringing 20-30PH to market every two months (the equivalent of 4000-5000 SP-30). |

I predict the next difficulty increase will be 20%
I predict it to be 11% I predict 11.11% jokes aside, it will be less than 20%, but higher than 11%, I choose 14-15% |

I just talked to a economics Phd and we analyzed some stats surrounding BTC. We made some good/worst case scenarios and took the average of those scenarios. Our price prediction for 2020 = 10,750 USD  It's a really good economist if s/he can predict price in 6 years time up to 5th decimal sign. As I said, we made some assumptions for worst /best turnouts and averaged those. This practise is called educated guessing and the finance world doesn't do much more than that and 10750$ no 10$75 cents It's just a common practice to give as much digits as you sure of. That is 10,750 would mean something between 10,740 and 10,760. While you probably meant to say something like "in range of 10K". Sorry for nitpicking. Now I get your angle. Yes, the average was around 10750. Best cases ranged from 15000-25000 USD Worst cases from 225 USD - 900 USD Your best case scenarios seem fairly bearish (b/c BTC has possibilities to go into the $100K range in the next 6 years), and your worst case scenarios do NOT seem to take into account the possibility of BTC going to zero, which is a real possibility, sorry to speak the truth... So ultimately, if you are NOT accounting for all of the scenarios, then your prediction is likely off, even if you are receiving the assistance and input of an economist phd. Those were the averages of different best/worst case approaches. Not the range of the absolute amounts. Ok... thanks... I look forward to seeing your work.. if you decide to let us see it.... $10750 in 2020 sounds possible, although it is 63% per year on average, which is much higher than any asset class. Could happen if we hit another bubble or super bubble. In the latter case, $10750 would be a trough after $35000-50000 super bubble. |

How long does it take BITMAIN to reply to an order???
It has been 5 days since I send them the remittance statement for an order of some S3s.I still havent recieve any feedback from them,not a word.I sent copy of the message,that I got from my bank with my shipping adress.Is this normal?
Bank? What website did u order from? I was in contact with them and I wanted to buy in dollars, so they sent me a bank account number. What was the website? You got scammed dude. It was bitmaintech.com. This was the e-mail: Hi, 1. besides bitcoins, we also accept USD wires.please feedback to us for remittance info when you decide to place order. 2. ATX PSU is OK, there are 4 PCI-e connectors for +12V DC input, but it only needs to connect two of them(total 30.5A) if without overclocking. FYI http://www.enermaxusa.com/psu_revolution87+.php3. Have you ever bought S3 from us before? do you have any coupon? 4. how many S3 do you plan to buy? we may request some discount if quantity is large.Best Regards BITMAIN This e-mail and its attachments contain confidential information from BITMAIN TECHNOLOGIES LIMITED, which is intended only for the person or entity whose address is listed above.

Thank you. it was send by info@bitmaintech.comHaha, that is a phat scam in front of your face! Well,is this the site of BITMAIN https://bitmaintech.com/product.htmif thi s is it,I got the e-mail adress from the contact info.: Business plans/proposals, custom service and RMA request: info@bitmaintech.comstrange story, maybe they got hacked or spoofed. |

Does it matter what set of 2 you plug the PCE-I connections into? If 1 side is damaged, but the other side good, perhaps that is why some people report better luck with 2, than 4? I been using the side closest to ethernet for all my machines so far, would switching the connections to the other side improve any sort of issues people may be having? If so which ones?
plugging in the farthest two (from the ethernet port) also works the same, not better or worse. i don't know what do you mean by damaged. |

Is there a reason why everyone is changing the thermal compound on the heatsinks?
because they want to do...something as most people experience shows, changing thermal paste in most cases results in NO effect whatsoever, but don't tell this to a couple of guys here. |
|
|
|
MX-4 is the best or one of the best, but it's not in Best buy. I haven't seen one case that convincingly proves that new paste did anything significant (in most cases people saw nothing/no effect). |

If Bitfury is paying $0.04 or $0.05/kWh in Iceland, and the average home miner is paying $0.10 to $0.15, there's no question about it: the home miner will have to shut off his equipment when one of the next few Bitfury DCs comes online.
I don't think that this is a correct assessment. Home miner could be doing mining for fun, as a hobby, or something else. Home miner can also SELL his used equipment. Where Bitfury will sell their used miners? As long as home miner comes ahead in comparison with straight buying coins (or even in comparison with just holding cash), home mining will continue. |

It's more complex than pure GREED. "BitFury" (Valery, the "CTO" - the ASIC designer) has aspirations for world domination through Bitcoins. Really.
Seriously? if so, then he already missed his chance because more than 62% of all bitcoins has been produced already (~13.1 mil=62.3%) |

If anyone is interested, I'm posting the stats on my two B3 units where one is slightly over clocked and the other is stock. I picked which unit to over clock based on the fact that it had the lowest hardware errors after running for several days. Note that both units are running at a colo facility with 208 volt power and temperature control. The stock unit runs about 38 degrees and the over clocked one between 38 and 39. I'm using 2 CX750M PSUs, one per S3. I know it's overkill, but I bought them before we all found out that the S3s are not over clock friendly. I used all 4 power connectors because I wanted to experiment with over clocking from a distance without having to go to colo and move plugs around. FYI, none of the plugs or cables have ever felt warm to the touch. Here are the stats after running for almost 6 days with the above configuration: | Frequency | GH/s | HW | DiffA | DiffR | Error Rate % | | 218.75 | 441.44 | 1,732 | 50,942,208 | 63,488 | 0.00339558387456823 | | 225 | 453.36 | 8,056 | 52,252,928 | 71,680 | 0.0153938274573601 |
The delta is that the over clocked unit is providing about 2.7% more accepts with about 3.5 times more hardware errors. Prior to over clocking the hardware errors were quite a bit less than the current stock unit. But the nearly 3% increase in accepts seems worth it to me. Note that I also tried a frequency of 237.5 on the over clocked unit, but I got 824 HW errors after 20 minutes. This seemed like an insane error rate, so I backed it off to 225. That's good stats, but why do you care so much about the HW rate? All what is important is production per time period. 824 errors if not possible to calculate without diff A and diff R numbers. maybe it is still low. I would say that if HW error (calculated properly) is less than 1%, then it is still worth it to go to 237.5. I have one S3 that has one asic with an X at 237.5, but total speed is still 464-465 GH, which is better than 441, so I stay with 237.5 for it. |

Seems like you overclocked the miner. right? or you applied a non standard DC input? A change of that capacitor will fix your issue. Those resistors are damaged of not? If overclocking did that, I'm not sure I want to try and OC mine now. I am one of a lucky few that got four miners that work stable at 440Gh/s on sock freq 218.75. With this hardware, overclocking id risky. But the question at hand is did you OC and get that damage from it and if so, what freq was it on and what did you jump to from it ? There's been plenty of people OC here and none I have seen reported these kinds of issues. To booradlly No I didn't do an overclock. But your symptoms as per the images force me to think like that. I used to overclock my gpus long back and got into this kind of isues. I usually get this kind of a thing when voltage of the chip(s) increased. Looks a lot like a capacitor blew after a power surge from something like nearby lightning, its almost identical to what the PCB on my LG monitor looked like after lightning struck the parking lot across the highway from my office. Are you guys using high joules surge protectors for your miners? If not, you are risking the same as shown (boards blown). There are plenty of thunderstorms in the summer in my area, so I stocked up at the Microcenter on a few of surge protectors. |

If you are talking about your diversification in crypto-currencies, then you are going to need decide between the various crypto-currencies - yet I do NOT see any crypto-currency being more long-term stable (less downward volatile) that BTC, and more than 90% allocated into BTC (as compared with other crypto currencies) would NOT necessarily be a bad choice.
On the other hand, if you are talking about 98.5% of your total investment portfolio being in BTC, then that is another story.
Personally, I have more than 95% of my crypto-currencies investment in BTC; however, I have less than 10% of my total investment portfolio in crypto currencies.
The level of diversification is going to vary from person to person based on age, risk aversion, size of investment portfolio, kind of assets already contained in investment portfolio, expected lifestyle (standard of living), when s/he began investing in BTC (meaning whether s/he has already experienced BTC appreciation), and other factors. You would need to calculate these various factors for yourself when deciding whether and/or how much to diversify away from BTC.
98.5% of crypto investments in BTC; that much of EVERYTHING would be crazy. Crypto total probably about 10% without counting RE equity, but rising steadily. Will probably stop at 15-20% or so and re-evaluate. Well, that makes sense.... and sometimes I like to consider my total investments in terms of what I consider to be liquid or quasi-liquid assets... even though sometimes, from time to time, it may be useful to consider, also net wealth or total assets, even if they are less liquid. a side note: in TX they make it difficult to access the home equity, so I just don't count on it at all because I don't plan to move soon. Maybe my kids will get it eventually. In Cali it is probably not possible because 50-70% of people's wealth is in their home. |

yes, that's fine. You don't want to bump them up to 237.5 and see what happens? Well, each miner is on it's own 1k watt PSU where there being hosted with all four power ports on the miners being used. That said, I do want to incrementally OC them with each step being left alone for 24hrs to see what extras I can squeeze out of these while being stable. That said, can these be OC'd from the webui or do I need to use PuTTy to get in to the miners ? Putty (PC) or Terminal (on a mac) I would suggest to skip 225 initially, and go to 237.5. In my experience, if they cannot do 237.5, then they cannot be at 225 either, so you save time. What do I use for port in putty ? I got the hostname / ip like this for all my miners where they're being hosted. 1.2.3.4:5678 So for putty i guess it would be root@1.2.3.4:5678 but what do I us for port ? I might have to ask my collo guy to open the port so I can use it. Also, what are the increments you an use besides 225 & 237.5 ? Basically I'm looking for an OC guide... I've seen it here before but god knows what damn page it's on. Forgo to bookmark it last time. how to ssh into miner: https://www.youtube.com/watch?v=72FU4Z_n0B4I am using Terminal, don't know putty, but the gist is, i believe, that you ssh into root@<you miner IP>, not port. Check the video and also click on "more" tab in comments. |

Regarding the future of bitcoin...
Does anybody here think that some bitcoin 2.0 will replace bitcoin as the most prominent crypto?
The analogy would be Yahoo vs Google for search and then the position to be a #1 Internet powerhouse.
In 2000 Google was just a single page with a search line (although working great even then) while Yahoo was a $150-200 bil behemoth.
Comes Monero (XMR)...
What would be the chance that Monero replaces BTC eventually as the best coin? 1%, 10%, 70%?
The wallet/account that Monero dev showed yesterday looked awesome.
Disclosure: I started buying XMR, but not sure what % to allocate to it vs BTC
you think shitcoin V0.0.1.SHITCOIN is going to repalce bitcoin? no NEW SHINNY SHITCOIN of 2015 is what you wana buy or ltc for fun. why would I buy LTC when it is almost EXACTLY the same as BTC? Also, don't be so defensive. I have to say that I used BTC for about a year already and there has been NO significant improvements it anything as far as ease of use, security, etc, except endless talk about regulation plus hedge funds involvement (phew!). There are a bunch of proposals that in most cases don't get implemented plus some esoteric things like Etherium and side chains (that went nowhere so far). WOW!!!! If the above bolded part is true, then that is NOT good for BTC to have a year without improvement(s) in the realm of ease of use, security, etc... ... Although we may need to flesh out what "etc." is? number of bitcoin applications? public awareness of BTC? liquidity options? purchase options? ability to avoid fees options? ease of setting up BTC accounts? fears about legality of BTC? the press's treatment of BTC? I want improvements in the BTC space too.. especially ease of use and security and some of the "etc.," as well.. whatever "etc." is? ease of use and security? uhrm, trezor? in my opinion, get rich quick hedge funds got on it BEFORE the underlying technology for mass use was created. A recipe for disaster, in my opinion. You are being wishy washy, Biodom. You are the one who made the assertion that nothing has been done in the past year regarding ease of use, security, etc.... .. Then an example was provided to show that you are wrong... you agree with the example, and then assume that was the only thing that was done... rather the burden should be on you to be persuasive.. rather than following up by merely asking a trolling-like question. In essence, you are attempting to side-step the issue and to detract, when you have been shown to be an exaggerator.  if trezor is the type of progress BTC made in a whole year, I would need to diversify more OUT of BTC (currently 98.5% in BTC). trezor looks neat, but means nothing for the mass market. It costs $119 and how often you use dongles (never) or misplace flash drives (often). Sorry to offend, but don't be so thin skinned, i care for BTC  |

Care to explain how this with the coupon works?
When do you get some? After each order?
If I wanna buy 6 x S3, should I do it in pairs by placing 3 orders and hope/use coupons on the second and third couple?
Coupons were only issued for s1, s2 and first 3 batches of S3. Nothing since. |

Miners need to sell at above their cost to justify their operation.
No, some (maybe most) small miners don't have to sell. I didn't sell (for fiat) a single btc that I mined. |
