Bumping again to update price and availability.
|
|
|
|

Bumping again as these are still available - it looks like the cost to ship outside of China is cost prohibitive, so these are more if you are looking to keep them hosted.
Price remains $375 ea., 2 available.

I'd like to buy them, but I'd want them shipped to me, so you think you can discount the pre-paid hosting from the price? Also since you are a client of Lee Group you think you can ask them to put together a shipping quote to a Canadian postal code? (I'll PM you that if they agree to ship the miners to Canada).
I'm happy to check on a price to ship them to Canada, just PM me the postal code. As for discounting the hosting, that is up to Lee, I can check if he's willing to refund this hosting that's already been paid and apply it to the shipping cost. |

I have 2 S5's for sale that are hosted by Lee Group. Hosting cost for each is $1.416/miner/day (about $42.5 per month). I've had a bunch of miners hosted there for months with no issues, and will still have miners hosted there after selling these 2. These include a PSU (not a rental - you actually own the PSU). Check the thread here - https://bitcointalk.org/index.php?topic=934581.0$375 ea. with hosting paid through July 20. Escrow can be handled through the hosting provider if desired. You can set these to mine at your own pool and check up on them through their online interface. If you don't want them hosted, Lee's group can ship the miner and PSU to you - you will have to check with them on cost, but it is quite pricey to North America at least. |

Live sheet is back up (mostly) - shows us -3.73% right now. Some things aren't working quite right (though I believe the standard difficulty projection is) - I expect everything else to be up by tonight or tomorrow, plus a tweaked experimental projection. Last time the experimental projection was decent over the last week, but I have some ideas to make it better. https://docs.google.com/spreadsheets/d/1qmF2knc5rSrJLESgQJYBz8mPzpKihmSzPPQUGH7pT8g |

+0.26 to 0.50 is left
and a lot of negative ranges available
I'll take +0.26-0.5. My apologies on the delay getting the sheet back up, I got caught up on another project. I'll get it up ASAP. |

The sheet will be back up for this one (and future ones), but I'm going to take it down for a bit after this change to make some internal updates. Since the diff. change is going to be about 1 am EDT, it will be down until sometime tomorrow. Shouldn't matter much since the first day doesn't give too much info. I'll post once its back up, it should be the same link.
Edit: All in all, kind of a disappointing period as the price dropped about as much as difficulty will increase. But it follows a couple good ones, and given recent trends the next one looks to be much closer to flat. The average has been 2-2.5% for the past few months, nothing has changed that makes me think that won't be the average going forward at least for a few more adjustments.

I purchased an SP20 from OregonMines over the weekend. I have to say that everything has gone smoothly so far, except for the outage that Oregonmines announced in this thread. Even that one hiccup was handled professionally, as they quickly got back to me once I noticed that it was down, gave me an estimate as to when it would be back up, and got it back up within that estimate. They also agreed to credit me for a full day, even though I lost less than a full day.
After expressing interest in purchasing the SP20, I received an invoice generated by Quickbooks from DG Rollins Mining, LLC. The invoice was for the cost of the unit, plus a month's hosting costs. OM agreed to run the unit underclocked, and charged me accordingly. I paid the invoice using bitcoin. I checked my pool about 10 minutes later, and the miner was already running. Other than the downtime mentioned above, the miner has run consistently and at the expected speed.
The one service I wish they offered is the ability to change pools myself through a web interface or something similar. Hopefully this is something that can be added in the future. That said, I haven't had a need to change pools yet, and OM has said that they will change pools upon request. However, especially with hosted services, I like to test out how the miner responds at different pools, so this would be a helpful added feature. I should add that Lee, who I suppose is their competitor, also does not offer this service.
Overall, I'm happy with my experience with OM. It appears to be a professionally run operation.
Thanks for taking the risk  What's the underclocked performance? It ranges from 1.38 Ths to 1.42 Ths at the pool, just about what I expected. Just an update two weeks later, I have not had any downtime or any issues with OM's service. This is no longer an issue regarding service. You are supporting a company that is associated with theft and fraud to satisfy your own greed. Honestly I hope anyone that invests in this gets burned, you get what you deserve. I guess if by purchasing a single miner and service I'm supporting them, then sure. But I have no reason to suspect that this company is associated with theft and fraud. Apparently they hired at least one person that some people suspect is associated with theft and fraud, something I found out after I made my purchase. However, I did my research, learned the real names of the people behind the company before they disclosed them here (it's real easy - they were never trying to hide it), and made a choice to risk an entire $400 (I know, I'm greedy as hell, if I'm lucky I'll walk away with a couple hundred bucks in profit, or I'll lose some money). While everyone plays guilt-by-association, I'm just providing the only facts that I know. Nobody has to listen to a word I say, and I'm sorry that you hope I get burned. |

Seriously the blocks have been flying since diff change, 10-12% increase projected & nonstop?! This isnt just variance, its outright slaughter.
I thought AM was fucking halted for the time being
Bitmain hasnt been doing anything or planned anything that I know of lately
spondoolies is sitting around twiddling there dicks
What 33PH just randomly came online?!
Im pissed & very confused lol!
I cant wait till sub $100 btc prices so all these megamines fucking go out of business.
Bitmain started shipping Batch 5 this week. That could be part of it. Antpool and Slush have also been extraordinarily lucky compared to their reported hashrate. The hashrate numbers you're referring to likely are derived from the number of blocks solved over a certain period of time - that doesn't mean the hashrate actually increased, it could be luck. For example, look at the spike in hashrate from March 10-12 on the following chart - the network wasn't 400 Ph/s then, and it probably isn't now. But unlike then, there is almost certainly some increase coming from Bitmain's shipments. http://www.coinwarz.com/network-hashrate-charts/bitcoin-network-hashrate-chartIt should be easy to estimate at least somewhat how much is due to luck. Antpool reports its hashrate, so it is fairly easy to calculate how many blocks it should have solved and compare it to how many it actually solved. For this difficulty period, we've solved 45 blocks more than would be expected if hashrate were stable. (See https://docs.google.com/spreadsheets/d/1qmF2knc5rSrJLESgQJYBz8mPzpKihmSzPPQUGH7pT8g/edit#gid=561061211) I don't have time to run the numbers now, but I'd be surprised if less than half of those extra blocks were due to luck from Antpool and Slush alone. bw.com has been lucky as well, and from what I can tell no major pool has been unlucky. f2pool stopped reporting their hashrate (or I can't find it), but they're solving blocks at about the rate they were before. Edit: That said, the luck happened, and it would take an equal amount of bad luck to reverse it, which obviously isn't guaranteed. That's why right now it looks like the increase will be 7-8%, but the round is early so the confidence in that prediction isn't that high. |

About 3.5 days to make a pick we have had 3 people change picks. https://bitcoinwisdom.com/bitcoin/difficulty is at (+1.39%) https://docs.google.com/spreadsheets/d/1qmF2knc5rSrJLESgQJYBz8mPzpKihmSzPPQUGH7pT8g/edit#gid=561061211has a big move up (+11.05%) 419 blocks vs 377 blocks really big shift here the last time we did +10 % or more was Nov 05 2014 39,603,666,252 10.05% 283,494,086 GH/s https://bitcoinwisdom.com/bitcoin/difficultyWhile there was some good luck so far this period, its becoming more certain that there was also an increase in hashrate. That could be due to a combination of (1) the ddos attacks subsiding or at least being mitigated (which artificially lowered the last two adjustments), and (2) Bitmain's shipment of S5's. (They may have gotten their large 500+ orders out before the smaller orders, which are arriving now). There's also the possibility, as you've mentioned that equipment was moving as electricity rates adjust with summer coming in the Northern Hemisphere, where I'll speculate a large percentage of mining occurs. [Edit: The good news is that these are one-time factors - so if we have a large jump, there's no reason to think that we won't go back to the 2-3% average we've seen over the past several months.] [Edit2: The price increase from the last couple weeks could also have an impact - exchange rate has an impact, but it may lag by a week or two... which would make me think there would be a drop off toward the end of this period or during the next]. I added an experimental difficulty projection to the sheet that factors in what has happened so far, as well as the 3, 5, and 7 day moving averages at various weights. Right now it is showing an 8.39% increase. I feel this is a little high, but we'll see. |

But of course even if it's variance (i.e. the hashrate spikes and then drops) it's still going to have an effect on difficulty. See a couple of spikes from the recent past, green is the 2016-block/difficulty line. Bow to my Paint skillz.
That's exactly right ... even if you chalk it up to luck, there would have to be an equal amount of bad luck to cancel it out. However, I think if luck causes part of a difficulty increase, difficulty is likely to correct the next period (holding all else equal except for luck), unless there's an equal amount of luck. |

Maybe the recent spikes are just luck? Slush's pool just did 10 Blocks in the last 12 hours, with only 12 Ph/s.
The price is down 14% for the week. It's $248 at the time of this writing.
Downward price pressure and no new efficiency hardware should continue to apply force against the difficulty.
AntPool had some massive luck today too. I wonder if the little extra BTC is also having an effect on the price. This should all sort itself out in the next week or so. It'll be interesting to see if Antpool stays lucky ... I wonder how accurate their reported hashrate is. Does it include Bitmain's own miners, for example? [EDIT: Actually it wouldn't make much sense for it to under-report its hashrate ... it would have to pay its miners more proportionally than they deserve] Assuming pool reported hashrates are accurate, we're not at 377Ph/s (which is the estimate for this difficulty period so far). In fact, pools that report haven't shown that much of an increase. Slush's pool has solved blocks at a rate consistent with a pool running at close to 30Ph/s over the last 24 hours, but its been constantly reporting just over 12 Ph/s. That said, even if its luck, its put us 40 blocks ahead of pace already. There's no reason to think bad luck will even it out, so even assuming luck has played a major role the past two days we're looking at a 3-5% increase this period. Possibly more depending on what Bitmain shipped. I'd be shocked if we jump over 10% though. That would mean 33 Ph/s was added to the network... seems a bit of a stretch. |

the neimeng data center is fine and the offline history should record under your account
we do set an account for each customer
now we also add one function to let you to submit pool change request
you can find it by click miner configuration tag, just below miner monitor tag
i already find two customer use this function, seem very useful
Thanks for adding this feature! |

Please move me to +3.26 - 3.5 (assuming we can switch) (read the rules, we can)

A lot of people wondered why we got cold right at the end. maybe some one turned 10ph off the last day and put it back on today.
The difficulty drop itself could have been enough to cause some to turn back on. In addition, I don't think a single 164 block day is any reason to think that a large amount of hashing power came on. We'll know more in a couple days. That's why the predictions that include data from the previous difficulty period are more accurate. I'm trying to work on one of those, but it's a bit tough estimating something that (1) has natural statistical variance, and (2) has actual and somewhat unpredictable growth (positive or negative). |

I'm hoping 6 turns out to be high. But hard to tell this early. Once next gen chips come out I think we will skyrocket. So far everyone is very very quiet about their chips it seems.
And I could be out of it but I wonder if litecoin difficulty of "Mar 19 2015 34,843 -14.53% 997,667 MH/s" was anyone switching over to BTC from Scrypt gear.
It's real early - if today (3/24) is like 3/14 (129 blocks solved), we're right back to 0%. In another 48 hours or so we should have a good idea +/- 3% of where we'll be based on the way things have been going. |
