In addition to the selling caused by the high price, there is ongoing sales of BTC that are just not optional. Bitmain must sell at least 100 coins each day to pay suppliers, workers, electric bill, and so forth.
We should expect that there will be "resistance" levels where the price brings out many seller. $500 is urely one of those points.
It's really hard to tell how much they have to cash out With data centers full of gear even with low electricity, that is still a lot of money. And they have to cash out to make next batches of miners I would think. Guessing they go to fiat and then buy miner parts in fiat. I'm sure they don't run day by day. I'm confident they have a good amount of rainy day funds to keep everything going incase it ever did drop a lot. They convert all coin, only coin they have is to pay miners and hashnest. Otherwise, comes in and its sold. Look at when they sold 500 s7 on HN, within 10 min of sale starting, the BTC price dropped and continued to drop till they sold out. 500 miners is almost a million USD dumped in 32 hours, the first 3 hours was a good chunk of that. When they sold out, within 1 hour BTC started going up again. BTC is a pretty small market from a liquidity perspective. |

I cant believe bitcoin is up to 445. Any one know why the price spike? Think this will have an affect on how many blocks we find since more miner will be turning back on their gear?
Many theories, I like the capital controls in China and people using BTC to move money out of China since govt imposed a 50k USD limit. But who knows. At this price and growing the diff increase will be 8-10 percent per adjustment till all new hash is figured in. Old turned back on and ramped up production of new. Bitmain alone is putting about 2.5ph online weekly via HW sales and hashnest sales. This price keeps up and 30 days from now we will have 600ph network |

Did anyone else in USA have to provide SSN to customs before they would release package for delivery?
Yes, Fedex called me for SSN, asked if business or personal. Now I only do UPS, less of an issue with customs |

Hello
Have a question.
What should I consider when chosing a mining pool?. I have a S7 B2 on its way to my house. It should be delivered on thursday and this is my first miner.
I have been reading about the different methods each pool work (PPS, PPLNS, DGM, SMPPS, etc...) and also we can find several pools on each method. Which method and which pool do you think work better and why? If two given pools work on PPS for example, how is that possible that one of them could have their luck on "-8%" (just saying something), I thought statiscally both of them should be "the same thing" (of course according to their each mining total power)
Do they have any trick I should take care of?
Is there anyway to measure efficiency of each mining pool without having to test each pool for several hours or days?
Thank you
Luck is just a laymans term for variance. If you mine on a pool having bad "luck" you'll earn the same BTC in the long run as a pool having good "luck". The luck on a pool just shows how fast or slow it has recently been finding blocks. Over time a pool will find the same amount of blocks to match it's hashrate, so a bigger pool doesn't earn more. A pool with 1% of the total hashrate will find 1% of blocks over time, and the payouts will be spread out over less miners than a big pool so they will earn the same over time regardless of current luck. A 1% pool can go long periods of time with bad luck, which you might not be comfortable with I was just using it as an example. PPS method has no luck factor, the pool might just be displaying the luck even though it doesn't have any effect on payouts. PPS usually has higher fees, so it's a personal preference, personally I avoid it since I'll make the same amount with the other payout methods just with more variance.
http://eligius.st/~gateway/ is my personal favorite, it's as close to pps as possible with zero fees. It does have long round times due to being a smaller pool at the moment, but during good luck your old shares from bad luck are paid. It also pays out in MINED coins, not the pool sending you BTC. So the coins show up in your wallet as mined, it's still just BTC just kind of cool. And being a smaller pool you're helping keep the blockchain decentralized which is good for bitcoin. If you need/want more steady payouts daily obviously you will need to go on a bigger pool, if it's one of the bigger pools I would just choose the one with the lowest fee and not worry too much about luck. Slush pool is also a good pool, I have never mined f2pool or antpool. One thing I would add is if you are very depended on ROI for hardware, or power costs then a smaller pool with higher variance can pay less. Because of large diff increases, like we are seeing now the more block you are part of in the diff window the better. If you get paid on 350 blocks in the 12 or so days at current diff vs getting paid for 5 in the diff window. That is even more important on a PPS pool since your paid based on network diff. |

Running against nicehash.
S5's would every so often crash the os against nicehash as it was switching rentals.
My remote pdu allowed me to cycle the power and bring them back up.
The s5's are gone now.
Just now my first s7 had the os crash with nicehash.
Did the remote pdu power recycle and it is back hashing away.
More of an impact when 5th are taken out rather than the 1th.
Now I only have a single S7 but haven't had this issue before. Up 2200 minutes still with nicehash. Only one once with 17 running against nicehash. Can't even ping the miner. HAVE to power reset. Pretty stable usually. Payout pretty good on MRR? MRR can payout good. Depends on what you set your rental rate at, I tend to set mine a bit higher then 100% and have had good rentals, but not much lately with the increase in hash network-wide and high diff. I like MRR too because I point all my miners to it and it proxies my connections so switching pools is a simple mouse click and all my miners switch together rather than having to log into each one and manually changing the settings. Can you use their proxy to switch all your miners to any pool? Even if not renting? Sounds like an easy way to flip pool all at once on your own gear and pools. |

Anyone powered his S7 using only 1 PCi-E 6 per board ?
I have powered them with only 1 cable per board for the last 2 days and they were working fine
Just today I read somewhere that it actually needs all 3 cables per board.
That's over 350W DC for 1 cable. The connectors/pins are only rated for a maxijum of 324W, and those ratings aren't overly conservative given the demanding environments mining puts on them (vibration + high ambient temps). Plug more cables into them, like now... Edit: Plus it violates Bitmain's ridiculous warranty terms... I'm doing 8 total, 2 each to outside boards and 3 to center plus controller. That way I can use 2 dell 750 PSU with 8 cables. Using high quality 16awg cables and breakout boards. No issues. Been monitoring temps of connectors and cables. Avg connect temp is 79F. Miner runs at 55-59c and ambient temp is 69-72F. That would be 175w per cable on the boards with 2 plugged in. Consumer PSU may not handle this since cables are lower gauge and will heat up more. |

Does anybody know of any decent data center for miners in Southern California?
I have no clue where to look for a data center ( with the exception to a multi-level underground nuclear hardened facility out in Iowa ).... what questions to ask.... what to watch out for.... etc. I would think that data centers would not like to have average joe schmos putting their equipment in their centers that have large corporations and what not hosted there.... just out of security sake. great north data is really pretty good http://www.greatnorthdata.com/https://bitcointalk.org/index.php?action=profile;u=400812Canada Based. My next order from bitmaintech and or avalon will be going to his place What are they charging per kw? assuming you buy like 10,000? Any setup fees or other maintenance fees? |

I am just outside Albany NY, not sure if you travel the 87 much, but I have 8 x s3+, 1 S4 and several S5's. Given shipping costs, maybe pickup is the way to go.
Let me know
Hello, i don't have a car ^_^". I'm tapped out in funds at the moment, but i will be looking to buy more S5's in the future. I may have to remove S3 and maybe S4 from my buying list, i only have 800watts of power free on my power grid for mining, so after that its replacing older gear, and replacing older gear with slightly less older gear is probably not going to be enough. If the price is right i would buy a working S5 from anywhere. If you have a concrete offer for 1 or 2-3 S5, i'd be interested to hear it, however it will take me a bit of time to replenish my funds. The next thing i'm picking up will be a single S5 blade, as soon as i can find one at a good price. So i was going to let this thread rest for a bit until i have budget again. OK, thats fine. I have the hardware listed other places also so lets check back in a while when your ready and I'll see what I have left at that point. I am now looking to pickup some deal. If you (or anyone else for that matter) have S3's already in Canada, shipping them here might be doable. Also interested in S4, S4+, S5, S5+. The S5 at least, would probably not be an issue if shipped from the US. Not sure about the shipping cost for an S4, it might not be doable. From outside Canada. I am close to Ottawa, if local drop off is a possibility. I do have 6 S3+ for sale at the moment and possibly a few S5's. This would ship from zip code 12110 if you want to see if that would work. I am looking for $100 per S3+ Its typically come down to 40$ shipping per S3, with the price you are asking, that would be 140$ per, about twice the price i'd buy them for, so we can scratch that. Then for a S5, i'd offer 270$+Shipping for one, but if you're asking 140$ shipped for a S3, it sound like you'd be asking 400$+ for a S5, which is also too much? (Delete and Repost) For the next 24 hours only i will be buying S3~ at 100$ Shipped per.As BTC keeps pushing up, even S3 and S4 become very profitable, thus I am going to ask 100 plus shipping for s3 and $400 plus shipping for S5 and $675 plus shipping for S4. That is still better then 90% of the listings on eBay and I guarantee my units perform to factory or better unlike some of the crap sold on eBay. |

You have too many conflicting statements, Sir. It's so confusing that I don't know what you are trying to imply anymore. It's just not possible to pull 32,000 watts at 120 volts (266 amps) through a 200 amp breaker UNLESS the breaker is defective.
OK, believe what you will. I do know several "licensed" electricians and had one confirm with me today, after these exchanges, that it is Per Phase on the Main - not total. So each phase can be loaded with 80% load and the main will not trip as they are out of phase and not an addition of current. Here is a list of miners and wattage that I am currently using - all at 120V. They alone are exceeding 200A in power usage - 13 x s7's = 15730 WATTS 8 x s5's = 4720 WATTS 1 x S4 = 1400 WATTS 3 x A2 @ 88 = 2250 WATTS 4 x A2 @ 110 = 4000 WATTS TOTAL WATTS = 28100 @ 120v = 234A The only 240V circuits being used are 1) Stove - 2) Water Heater. Even with the miner loads, I'm still able to use all sorts of other electricity - IE this computer - a couple 1000 Watt gaming machines, a 200 Watt Laser Cutter, air compressors, electric drills, radios, garbage disposal, hair dryers (when gf needs), and charge my Chevy Volt. You are saying this is impossible, unless defective - seems to be working. I'm beginning to wonder if you have a 300 amp breaker thrown in a main panel rated for 200 amps. Also, when you say, "All on 120V," are you using 2 pole or single pole breakers for your rigs? Isn't a 200 amp main at 240 volts? So it would be 400 amps at 120v? Use both legs on each breaker 200 amps max One leg on each breaker 400 amps max Same power/wattage either way Since we are talking power, any way to take two 20A 120v dedicated outlets and make them 240V externally? I don't have access to the panel and only the outlets, but each is dedicated on its own 20A breaker. Just asking, probably not, but worth a shot. |

Back to topic. My batch 2 comes tomorrow.
Orders on 2 and 3 are done.
so if you ordered on the 21st of oct or later have you received shipping info?
I still have 4 X S7 pending shipment, 2 from 10/16 that were batch 2, 1 on the 22nd batch 3 and 1 on the 23rd batch 2. No shipping info yet. I have only received my 2 Batch 1 from 9/8. |

Spreading hashrate amongst pools also helps with variance if you have the hashrate to spread. And as Kano said, there is some improbably bad luck happening on other pools at the moment. When difficulty was rising around 20% at every difficulty adjustment then only getting one or two blocks in a difficulty period was a huge problem in terms of ever getting ROI on a miner, but that isn't happening anymore. Difficulty adjustments are relatively small in comparison to the overall difficulty so sitting out some bad luck waiting for better luck is more realistic now than it used to be.
Good point, I was thinking about this as I am powering up some S7's I just spent a SHIT load on money on, Next 1-2 months I think the Diff will be going up about 5% per period as a lot of S7's and more power from Fury is coming online. That said, variance is a problem as you need to make ROI as FAST as possible before the next Diff change. I have been on this pool since early June and very happy with the Pool and support from Kano. But now that I have over 12K in miners to payoff, variance is an issue. Prior to these S7's, I bought mostly used S5 and used s4 so recovering the hardware cost was not as big a deal since I expected that to drop to near zero. But these expensive miners need to pay off FAST, or at least 50% of the cost and sell them while they still have value. Anyway, lets see now the next 2 weeks runs on luck. |

These Batch 2 and 3 miners probably won't get shipped until,
* Price of BTC goes to $300-$315 and reverses back down. I think they are holding them right now and mining with them so they can dump.
*Or will ship them on November 5th as its the last delay day.
Mining is very profitable at the moment.
yeah while it is a bit annoying. I do have 2 mining as I type. both work fine. I finally got my Batch 1 units, two of them. One does 4.88 avg while the other 4.63-4.68. Are a lot of people seeing this? I paid the full price of batch 1 and pretty pissed I got a batch 2 unit, guessing by the hash rate. I tried to OC it to 618 and 625, but not much difference, a lot more HW errors with minimal hash gain. |

Thats what i am talking about!
379092 (Main Chain) 2015-10-16 00:12:37 Kano CKPool 000000000000000006808ff46b763394d024d2930179513f57e9035dcb3fb6d3
FIRST BLOCK OF DAY!
Now just 2 more that are on the light green side and back to 100%
|

|

Kano,
Does the current 5N really go back more than 362 shifts?
Or is the "red line" not showing up for some reason?
I also includes all the shifts since the last block so yes the start of the last payout has moved off the bottom of the page. Edit: block  Holy shit, about time. Make it look like a christmas tree now for next 4 blocks. We deserve it with all the red this month... |
|
|
|
|
Holy crap, now even Bitminter got a block over 2 days and over 350%......Come on, let hit it already
|
|
|
|
|
So the Solo CK Pool gets 3 blocks before we get one? WOW thats crazy
|
|
|
|
|
Come on bastard block, lets get this under 200%. Diff stayed low for another 13 days so lets take advantage of that!!!!

Well, if you guys want, maybe we could pool some rentals sometime.
I'm sure we could figure out a person to hold the money, if not one of us 3 maybe buzz OGNasty. He might be interested.
If you don't mind that I ask...
What are each of your strategies?
Deposit X amount of BTC and use unlimited speed until the coin is depleted?
Deposit X amount of BTC and use speed ranging from 100TH - 500TH - 1000 or more, les, etc until the coin is depleted?
Deposit X amount of BTC and use low speed say in the range of 10TH until the coin is depleted?
I believe the last post I saw someone mentioned 200 TH was used a few times?
Appreciate any information you care to share.
I'm open to a 1btc pitch-in to a large rental. Need to get the good luck vibes going again. I have 500th running right now, still 4 hours left. If you put in 1btc @ .0079 for 500Th that will get us close to 3ph. Maybe someone else can do a few hundred to get us over 3ph. |
