That's a hard hit but let's see if we can stick in this diff range until the halving  A hard hit but not a knock out. I think once next gen chips are in production and hitting specs... we are in for double digits and I don't know how long. And that scares me. I think S7's they are making last bit of profits they can before having. But once we see next gen.... I will admit I'm afraid of it for home/hobby miners. As long as they sell gear to hobby miners there will be hobby miners. Just less of us. Now I'd say they could kill us off if they only build 10000 watt miners. I can provide 30 amp 240 volt circuits. Two in my house and three in the solar array. That can do 5 kwatts 24/7/365. Most home miners can't do that. So they will be dead soon. Maybe with in a year. As many miners can do an Avalon 6 in house or an office. If you have free power and run an avalon6 you can do it for a long time. If you have free power and the gear is 6 or 7 kwatt you are dead. That is when we die as home miners. |

Has anyone bought and done some testing on the single fan batch? What were some of the results?
a loud miner that can run at stock freq 700 in a 71 f room. I did see this post on the s-7 one fan thread |

Yeah I was running. 150 th for about six hours. So I then started building more eth rigs
I had lots of issues with the build and did not check bravo pool so when ppoc hit the block I had 3 hours left on my 150th rental. It ran out at three in the morning. So when rozo hit I got .39
Total of about .8 for the 2 blocks and I spent about .37 in rentals to get the .8
I was now at 0 for this block so I put up 25 th for a bit.
And I finally got the eth rigs set up. 82 mh
So all good.
What would really make the week would be mmpool popping a block

nice so I went from a small profit to a good profit as my last rental wrapped into the rozo block.
I tossed up 25th just now.

hello i have 3btc to build mining rig, before i build it, im confused because so many new algo for altcoin.
anyone can give me some idea..?
first off do you have zero gear? no parts nothing? |

From my spreadsheet, I use =24/(Difficulty*2^32/10^12/60/60)*25 for the BTC rate, which currently gives 0.00281463. Yeah, that formula could be greatly simplified, but you get the idea.
To make the math easier I mostly figure the pool fee and earned transaction fees to cancel each other out to within a few tenths of a %. That leaves me:
Nicehash 0% = 0.00281463*0.97=0.002730191 (0.27)
Similar results. I too am now using a long term 107% number, though I do notice that is trending upward.
I have fixed orders at 0.0028 and 0.0027 to anchor a good spot in the order queue, and I have several floating orders that my bot moves up/down between 0.0025 and 0.0030 to maintain a average rate.
At 0.27% of the pool for 90TH, I have a 1 in 370 chance of being a block finder. Assuming about 150 blocks per month (1 in 75 chance of a block find hitting a prize), that is a (1/370) * (1/75) [a.k.a. 1/370/75] = 0.0036% chance of hitting a prize (1 in 27,750). That is the back of the envelope version. I don't really consider those odds into any of my decisions.
but if you increase to 180 th only during a high cdf spot the math helps much better to win high cdf then the steady flat number of 90th. I have 25th-28th in real gear here. It stays. I spot rented on some of the high cdf blocks below. 752 406348 25.49482709 2016-04-08 21:00:35+00 Matured 578,233,238,077 346.556% 0.969 36 - I got 6 blocks on this rental 745 406042 25.38250979 2016-04-06 17:05:10+00 Matured 432,475,516,451 259.198% 0.925 43 - no spot mining 736 405758 25.35573784 2016-04-04 20:24:36+00 Matured 824,764,252,251 494.310% 0.993 52 -- I got 10 blocks on this rental 726 405383 25.35108456 2016-04-02 08:12:57+00 Matured 424,062,913,997 254.156% 0.921 62 -- no spot mining this is our high cdf guy belowBlock #745 e46btc with a CDF of 0.925 (259.198%) at 2016-04-06 17:05:10 UTC If we get to 250% I will spot rent again. The high cdf part of the game really is cool as it does encourage more rentals from a guy in the 1th to 100th range the low cdf is also clever as it discourages insanity at playing too much during a high cdf spot. I believe this is why kano has both prizes. Note I pulled my quotes out as kano does not like tons of quotes. |

What is the math for the low cdf and the high cdf prize chances? If we are in a high cdf block is it worth it to play 0.0030?
Okay if you are in the spot of a high cdf block you can see it is there. So if you hit a block you do become the leader of high cdf at that moment in time. This means you have a 50-50 chance of winning the avalon 6 if it holds up. Lazy math is 1st prize = 1btc (sadly the price of a sale of one used is that low now) second prize = .1 btc total = 0.55 btc added value Obviously that leaves out that you can later lose that high cdf. So for arguments sake lets say added value in a high cdf spot is 0.5 btc could be higher at most if you want to say it is .6 because it is new. Fine So if I rent at .0030 I am due back about a 98.5 % return. So a coin should get back .985 btc I should lose .015 btc going for the high cdf. I would suggest that is too high to pay. but spend .1 btc on a .0030 rental loses on average .0015 btc spend .1 btc on a .0031 rental loses on average .0046 btc the chance of hitting a block with a .1 rental is about 1 in 250 .6 btc divide by .0015 btc thats about 400 to 1 payoff. .6 btc divide by .0046 btc thats about 130 to 1 payoff So if you qualify for the prize since you are an under 250th guy playing .1 btc at .0030 is still a decent move. Ie the math is in your favor. an do not forget when you are renting .1 btc at say 200th you get around 4 hours. if you do this when we are at a high cdf spot you could get silly lucky and hit back to back blocks thus leading in low and high cdf. (the odds are higher then 62,500) So based on past performance . In a high cdf spot you can play up to 1 btc at 0.0030 and still not be betting at 'bad' odds. This does not mean you will make a dime it just means the odds are not against you. |

rentals are cheap today boys. get them while you can.
I'm not sure 0.0027/0.0028 is cheap anymore after the diff change (I'm showing those as 0% and -1% after the fee). We've pretty much adjusted downward to match what 0.0029 and 0.0030 were. I did get a few 0.0026 bites today, but they were brief. I ran the numbers on my rentals and I'm now up BTC0.76 since I began!  Nice! 0.0027 is just under the correct number but reality is if you base your figures on kano pools life time record take 0.002727 x by 1.0841 = 0.002956 thus in theory a play on 0.0027 0.0028 or 0.0029 all are good. of course lower is better. this screen shot shows . 1.0 th which is the fee less number 0.969 th which is the after fee number. There are 2 more factors the contest prize chance of hitting low cdf and the contest prize chance of hitting high cdf. Both have a value for your rental price. But the math is more complicated. You also need to be under the cut off of 250th to qualify for it.  |

I was also paid in full. Thanks

Rentals from where? I have zero experience with rentals and trying to figure that piece out, I normally just mine with 4 S7's I use nicehash/westhash if you need help you can pm me |

Yes it is from that page I noticed the color.
But I don't understand what it means to have a bad luck in solving a block ... Does it means the miner is slower than expected or something like that ?
(newbie question)
I was thinking that a S3 solving a block today was a lucky thing.
Insanely lucky for your s3 at 500gh but our entire pool is 35ph so not so lucky for the pool. our full pool is 70,000 x your 1 s-3 |

hey i just solved at the moment my problem all my problems come about this fking AMD drivers i have try a lot of old driver and i found the 15.11.1 nad its the best one i had my hashrate speed corrected and pool found my shares thank you for the time you spend to help me
Good I just did an Amd driver install an hour ago. Amd driver corruption issues are very common. |

If your are in windows:
1) Open control panel, device manager, are the 2 card there without an ! mark? If not, try to reinstall catalyst driver (15.12) (un install it first)
2) run ethminer --list-device, are your 2 card listed?
yeah it is most likely a driver issue I always like msi afterburner as it helps with multiple gpu settings and if the gpu's look wrong you need to uninstall the amd driver package then reinstall it then check it with msi afterburner. In fact I had this issue this morning with a rig holding a r7 370 and a r9 380 The r9 380 was really weird and the r7 370 was fine. so I went to msi afterburner looked at my 2 gpu's and the r9 380 was locked on every setting. not right = corrupted amd drivers (common problem) I went to program uninstall pull out the amd driver I went to amd 15.12 download link re installed the drive. I check msi afterburner and I could now alter the fan speed the clock on the r9 380 so I knew it was fixed. I am now mining with both cards. |

Thanks to be honest we do not really need to caluclate much, Most of it is down to the power you use but as we said we have a offer from a large factory to split the rewards with them, So power cost dose not come into the equasion. Its really the hardware we need a nudge in the direction of. info on whats being developed, whats available now, what people are running and what sucess they are having is a big factor for us to consider right now. Okay at this moment there are two pieces of gear the bitmaintech s-7 the avalon 6 Both are long in the tooth so to speak meaning newer gear will be coming soon. You are in a 'free' power position so buying older cheaper gear can be a good move for you. It is in a factory so noise factor is not an issue. I would suggest getting Avalon 6's and s-7's 2 of each would set you back about 2000 usd power supplies maybe 600 usd shipping + vat = 600 so 2600 usd is 2260 gbp this gets you started. PM me if you have more questions. |
