Okay forum helpers. shutefight has present hatred to share here with miners community. Bitmain is kind of devil spirit to drink blood of women and babies. I make miner loud with new plug in mining farm. Get so hot in chicken coup I cant sleep there. I goes out to barn and while making sleep chicken coup goes on fire!!!! it cant be gone away so is just ashes now!! No chickens. no miner. no chicken coup. now wife has hate on me to leave me and take babies!!!! Bitmain then sucks more blood. sells more miners for $900!!!! Never shutefight have this big evil and hate to a person in life. I peaceful man but should have army to have war to bitmain. Howthis terrible hate enemy of man be alive??!!!?  !!!!!!!!! This is your fault and not bitmain. If u did not have a proper mining swtup, u deserve it. Wtf man, putting it in a chicken coop barn...... These things are not home miners. |

Whether we like it or not, S9s are still very profitable to buy and run. I've been hearing arguments about difficulty increase for a year now. True, the BTC price jumps helped. But until BTC price drops to USD 2500 or the current difficulty triples without any increase in BTC price, S9s will keep running (approx calculations). Focus on getting a good colocation to place your miners or build a colo yourself. Your machines will run for a very long time if you keep colo costs low.
Also, regarding the newer machines that have come/are coming to the market. I'm excited to see competitors, but I really want to get a few hands-on reviews from regular guys like us, before deciding to stop supporting S9s.
Eagerly waiting for the GMO machines...
I dont understand. If btc falls to near 2500 levels, u gonna take a few years to break even or never break even. It will probably never occur as new miners come out by then. |

1:24pm us eastern time L3+ still on sale
for 2378$ how about those already paid march batch? How unfair is this bitmain ?
L3+ is gonna be like D3 is soon
Actually delivery time wise, the promise was march delivery and it is not march yet. So, it isnt wrong. I have L3+ coming for march delivery too. It would be nice if they sent it to us early but it is their choice yes, not a guarantee. |

What amount would you consider to be a low overhead per S9?
I can't give you a hard number bud! Those with the lowest capital cost of equipment and the lowest electrical rate in the simplest of terms. It is entirely plausible that in the future bitcoin mining will only be done by manufacture's as they will have access to the lowest possible priced units. It's also plausible that at some point manufacturing costs begin to approach the unprofitable mark. That is assuming tech flat lines as well as coin price. Think about Bitmain and their cost to manufacture a unit. That cost is A LOT lower than current retail pricing. Combined with sub $.05 usd/kwh and you can see how easily they could outlast any retail purchasing miner for a LONG time in the event of declining coin price and a prolonged low coin price. What happens if coin price falls to 4K and sits there for 5 years. Most miners are betting against that as are most folks in this forum in general but it's not an impossibility! It's also entirely plausible because BTC has the possibility IMO to go a lot higher in price that we see a much larger profit window for a long time to come! Until we can predict the impossible we can only speculate and ENJOY the fuckin ride! U make a good point here....but i dont think bitmain will not care for its customers like that |

If u paid 2300$ for a miner and u are getting 350$ per month thats not so bad, u are gonna ROI in 8 months. BUT, price will go up eventually, first months of the year are always bad for btc price, then the price starts increasing more and more until december
I wonder in what business u can invest 100k and get ROI before 1 year and make a return of 12% or more monthly
Ppl are still profiting from Antminers s7 right now and they had them for 4 years AND THEY ARE STILL selling the damn things for 1100$ when they bought them for like 500$. So you are looking at makiing profit for a whole year and getting AT LEAST your money back by selling the S9
Dont worry, if profit gets too low a lot of miners will go offline and difficulty will get easier or it will go up in minimal %
PD: In the calc i use a 13.5 s9 is giving 430$ monthly, also i doubt ull choose a a day/hour to sell when it is going down for example today's high was 11700
If that rate is going to be the same for 8 months, I would be happy. The miners will not go offline even if profits are low. People will just mine. Look at D3 for example, people are still mining even if it is low profit. Low profit is better than nothing u see.
all this is because of CME futures contract that will expires/expired on 26th of jan. on 17th of jan Cboe futures contract expired at 10900$ and bears win and just after 5 hours 200 billion dollars came back in market. so we may see a good pump in alts and BTC too after 26th jan.
Meanwhile in korea some banks will work with crypto exchanges with new taxation rules from 30th jan.
BTC lightining network is coming
CME BTC future expired on 26th jan.
one Japanese company started part of there salary in BTC
So all this indicates that big players, banks, companies and whalesOne cannot assume that wat happen last year to prices will do the same thing this year. I hope u are right buddy  |

You guys have covered the issue of a lightning strike affecting the power to the devices - but you must also consider a more vulnerable issue - the network connection. I have seen lightening strikes wipe out entire networks through the ethernet cables initiating through the internet connection. A voltage spike to the network connection to a miner will fry the controller. The best way to protect from this is to use a fiber link somewhere between the Internet connection and the miner farm. Electric surges cannot pass through fiber.
How to use a fibre link? Can it be used in a cable modem setup which uses cat 6 cables? I am not using fibre internet. I assume he's talking about using a media converter, going from UTP to fiber (and back) is common in the structured cabling world. I haven't used one in a long time but they even have coax to fiber media converters if you have coax and you wanted to protect the modem as well. If this is a "home" type set up I would avoid the media converters and would just get an inline ethernet surge protector. Avoid the real cheap ones make sure to look at ones that are rated for "lightning protection". Something like this one: https://www.amazon.ca/Ethernet-Surge-Protector-Gigabit-1000Mbs/dp/B00805VUD8Please note I have never used that actual product I just did a quick google search on ethernet cable surge protection and that was the first one from amazon that popped up! It is just an example, do your own research as that one is probably overkill for a home miner. Noted all your info. Will reaearch it. Thanks |

Do you expect next batch of S9 to go for sale below 2000$?
Because the profitability is down from before? I think news sources created a media frenzy which caused it. I got a feeling it wont be below 2000 though. I hope mining didficulty drops. It is way too high now. While I can't comment on the S9 price, I feel qualified to comment on difficulty. I expect difficulty will continue to rise, until it "catches up" with BTC price. I think the best you can hope for is a slowing in the rate of increase, as long as the price stays in the $11,000 range. Since 2013, I haven't seen a sustained decline in difficulty that lasted more than 2-3 cycles. I have a seen it "plateau" for a few months, but that didn't last more than 6 months or so. Now that folks have seen that BTC can spike to $20,000 I think it will be a while before folks give up on the dream of "getting rich". I expect that mining hardware will command a good price for a while. FOMO will take months to dissipate in my opinion. The media should stop sensationalizing things as if it is so easy. Those ebay prices are juz nuts high. The thing is if btc price has to keep going up alot for mining to be decently profitable, it would be far better to juz buy btc than mining equipment. Last year btc went from 800 to 10k now. Thats a 12x increase and difficulty increased to the point mining is only so profitable now. If btc has to increase 12x again for mining to be decently profitable at end of year, wont it juz be better to buy btc than to mine?? And it is not likely to increase 12x this year it seems. If price doesnt increase but difficulty increases, this isnt gonna be good. Lets hope bitmain retains the monopoly. More manufacturers and difficulty increasing is the last thing needed right now. Just my opinion and I could be wrong. |

mate dont use cryptocompare calculator it's worst calculator, it says you mine 0.013 dash per day dash price is aroud 800 so 0.013*800=10 usd per day not 5 the calc likely is, as you say NOT correct, but I only mine 0.009 dash per day! 0.009x 800 is 7.20 usd ..but no way do I mine over 0.013 per day! them days are gone.... what is a more LEGIT calculator? (more or less) i usually use coinwarz calculator u can add difficulty by yourself there and also i check average block difficulty for 24 hours so i have a clue what number i should add it to it. this way i have some kind of clue how much i make per day it's usually -7% to -8% difference from that calc i usually make around 0.008 dash per day with my D3 only 1 never really could figure that one out......i understand the add your own difficulty rate..just never have a clue...so I just use the snapshot method or KISS principle.... on a calc...but I guess the calc I picked sucked for that purpose.. not sure how you are getting 0.008 dash per day..I'm getting 0.009 per day for 2 das miners at 35gh? i'm on prohashing and here is my earnings  Is prohashing better? |

For those having a dead hashboard we need to regroup and send a strong message to bitmain to have a quick support.
For those interested by this approach. Please send me a PM and I will add you to my message.
At the end of the day we invest a lot of €€$$ and we are loosing money everyday and we all know it will be difficult to catch
Eh... won't they just send you to their warranty? Dead boards are really common with most anminers, S9s lately have been terrible. S9 and L3 is a long term investment you have you ROI between 4 to 9 months because it is mining different crypto. In our case it is a short term investment. Most of us have lost 800$ because of dead hashboard next week we will have maybe 8$ per day who knows bottom line we are losing money instead of few days to recover it it will take months and ROI is even longer I understand your frustration. My point is, quality of their products sucks and they don't give a shit. You can try to "send strong message", they will laugh at you (if they even read it). My point of view, but good luck, I'll be glad if these assholes change. I agree with you that bitmain is the only manufacturer....they have the global Monopoly but you need to try I already got some people interested U do realize that more manufacturers means more difficulty level right? And difficulty is too high already. |

Hmmm currently 6 gpu eth mining rig is now more profitable than an S9 or L3. I never seen this before....
Gpu mining is alot easier to do and by should give less returns by right.
Maybe we are in for a BTC price adjustment at some point soon? Couldn’t come any sooner, beforr all the S9s are not profitable anymore. I think btc has gone up alot recently and may not move for abit though. Same for eth. I wont say it becomes not profitable but it will be very low and roi will be too long for new miners especially. It is sad that gpu makes more considering they are far easier to do.... |

We just recently had a thunder storm here which made me wonder if I should unplug my miners in case of a lightning strike. Also sometimes the power will cut in and out. I’d imagine it’s probably not good for the miner if the power cuts in and out and it’s trying to reboot.
U need to install a surge arrestor at the distribution box. It costs some money but is important. U dont want a strike to fry it. |

The foundries are currently ramping up their 1st Generation 7nm Production and it looks from an article just put out by Scotten Jones that most of the volume targeting the 7nm process node is waiting for EUV in 2019. Check slide 13. Will manfacturers be able to continue to get better efficiency from Bitcoin miners by moving to these more advanced nodes? My first inclination is to say yes. Moving to 7nm is going to help achieve better efficiency. The glitch to this thesis that I am trying to wrap my head around is The E-bit E10 18T. They say they are using 10nm Samsung chips but are only able to get 10% better efficiency than the 16nm TSMC Antminer S9. On TSMC website they say that moving from 16nm to 10nm gives ~35% better efficiency. http://www.tsmc.com/english/dedicatedFoundry/technology/10nm.htmWhy didn't E-bit achieve better efficiency than that what they are announcing? Do you think they compromised efficiency to increase speed to shave some money on silicon? Or is the Samsung 10nm that overrated? Their cost is also another issue. With E-Bit E10 18T miners for March release sold out at price near $5000. https://www.semiwiki.com/forum/files/Scott%20Jones%20ISS%202018%20Presentation.pdfI guess their chips juz not as good as bitmain? |

Would you want the profitability at that time, or compared to some price?
For example, in Jan 2010, the profitability was negative, even though you were getting coins that could be worth hundreds of thousands at today's prices.
If profitability was negative, it would be better to switch off miners and just buy coins from the market. There was no market in early 2010. BTC had no value. I see. Those ppl were smart |
