Sorry to everyone, I did not do a good job following this topic. I sold the unit to VirosaGITS due to First Come First Serve basis. Though he did not reply to the thread, he did inquire via PM and that PM time was before the first reply. The unit has been sold, delivered, and escrow was released to me. I appreciate the patience VirosaGITS had with me, as since this post I've been MIA due to many reasons (Transitions in life, etc. Growing up sucks). But it was bothering me that people were literally calling him a scammer for not replying to their escrowed offers.
Thank you for this! At this time I have no more items to sell at this moment. Thank you everyone. I'm glad everything turned out well! Thank you so much for the unit. It look like its one of the older units but it is working very well. My small mine is growing steadily  |

My next step is prototyping an 8-chip small board, as a first test of power systems and integrated controls. All I have to work with is BM1384, unfortunately, which are noncompetitive and can't really be had in quantity anyway. If it's good enough I might try to work out an exchange thing where folks with dead S5 boards can trade them for working pods made with pull chips. Sort of a version of Technobit's Minion exchange for HEX4M boards, except of course for the part where everyone gets ripped off.
In case anyone's wondering, I just now thought up that exchange idea. It's entirely possible that I'll make exactly one board as an in-house test and then do nothing at all with the design, proceeding straight to a 30-chip board sized for an S1 instead. I like the idea of a nice adjustable CPU-cooler'd pod but it has to be economically feasible.
Okay I have 1 s-7 in house and 1 s-7 on order that makes for 6 boards. I would send a board to you when you need it. I would love to see you get some better chips. I think he was planning to do this on S5 ships. If he could get his hand on S7 chips, that would be awesome, but i suspect they might be very hard for him to get ahold of in sufficient amounts to start producing batches of those hardware. He'd probably be happy being able to mess around with them however (?) |

Even though it is no limit, there kinda is as far as good posts. There are only so many hours in the day and only so many posts that a person can add content to. If you posted in everything with crap you would be temp banned for insubstantial with sig, and kicked out off signature.
But Bit-X is the gold standard as far as I'm concerned I have been with it a long time. Their no limit is nice with it running. If you have Hero or Senior member hitting 1 BTC a year is very doable. And possibly more depending on your posts. Once you hit hero pay is pretty nice. But really full member is where pay starts to get worthwhile.
Indeed, i am trying to turn this into some kind of part time job, but at some point you lose focus and the creativity go away. So its best to just go do something else and come back and instead of reply to people who replied to you. Its much easier on the mind and its more proper discussion than just posting in every thread on the forum even when the threads are bad and there is nothing of interest to talk about. Your trying to turn a sig campaign into a part time job? If so you are overestimating it a bit. A signature campaign is meant to supplement a little income from your normal posting. It is not really meant as a part time job. If you are doing it as a job meaning going for quantity and payment kinda opposite as what i tell people they should do. I say use the forums normally as if you were not being paid. This prevents inflation of posts to make it like a job. I don't know, with the income on post that you have, it would be enough for me to live here in my situation. That much is about how much i want to make. It is enough to pay the rent and eat. Basically 300USD is enough. I already have another source of income, so that is why i compare it to a part time job. I don't think posting 200-300 posts per week is detrimental to the post quality if you're able to have steady back and forth discussion with people. I've seen a lot of people who do 200-400 posts per week(and maybe even more with how many alt accounts they have) and they just post one liners that have no relation with what was just said before. So i don't think 1.2BTC per month from campaign sig ad is a bad target for someone thats stuck at home all day everyday and actually bother commenting on other's post and actually reply to people replying to him. Unlike most sig ad posters around here which post generic stuff all day every day. I guess I'm just a little of the "old school" of this. I think it should be a supplement from your regular usage. Some users are very high in posts yes and others are few. The biggest part I don't like about it being a "job" is pay is linked directly to posts. So if going for a job just is not in my mind the right reason to do a sig campaign. But I am one person with my own thoughts. That could be right or wrong. And it's nothing against you I should throw that out there. I just think supplement regular activity is best way for it to work. Well i like keeping active on the Forum, i get to stay up to date and pick up good deals on the marketplace. The pay per most post (since Bit-x doesn't cover every boards so i'm not rewarded for all my posts) motivate me to post better and its all those post together that give a bonus to my income and get that one extra BTC, i see its reward equivalent to a part time job. Its the reward i get that fulfill the role that a part time job would. After all it does take a nice bit of time from my NOTbusy schedule. Its not a part time job in the sense where i clock hours to get paid. But it does motivate me to keep at it. Maybe confusing but thats how i thought about it before getting called out on it. I appolgize if you felt called out/took offense. I did not mean for it to be pointed at you specifically. just that I thought in general it should not be used as a job. So if you feel called out i appolgize for that. I could be wrong as I am one person. I just see it in the space of extra income from normal usage, not as a job. And again I mean no offense twords you. Ah it's okay, i was more interested in vehiculating the way i see than respond to offense taken. None was taken. Its just that for me, it fill the need of a part time job, i'm suppose i should of worded my statement differently. But i still need to keep in mind this campaign can go away pretty much at any time, so to not rely on it too much and take care of it the best i can. Some campaign don't even pay 1BTC per year, so... |

Yes well, in term of modification that i can do, there's stripping the 240v from the electric heating and i guess that will also somehow lower the overall amp usage(?).
Regardless it would let me use some yummy PSU. But i know and understand that i'm inherently limited since the continuous load limit would be 100A and i need headroom if i want to use the oven without resetting the breaker in the electric room in which i have no access to.
I don't use a whole lot of electricity outside of mining, but i still need the hot water tank, the fridge, oven and A/C in summer.
Have you looked at electric heater breaker? I would be surprised if it is 240 in a apartment. I would guess you have cenrtral heat/air in apartment. But i could be wrong. Assuming you have washer/dryer then decent chance of 240. And hot water might be but I would not touch it as any leak would be horrible if cord for miners got it. With having no access to electric breaker you really won't know a lot about setup. And if you experiment trying to find out the land lord will not be happy if your tripping breakers a lot. I do have access to my outlets's breakers, but the panel itself does not have a main breaker. So if i overload the 125A for the complete panel, the breaker switch for that is not in my apartment. For heating, i have 2 * double 20a 120/240v breakers. I was told that was most likely on 240v. I'm more wondering what i will get in my next apartment. Since i don't absolutely need to go through the trouble at the moment. I'm close to 10kW and i don't really want to go any higher since the board says 125A limit. If switching to 240 would lower my amp usage by half, that would be niice though. If its as simple as to bolt the heating's wire in an outlet box and then plug a 240v psu in, then it could be doable to easily replace it back without it being noticed when i need to give back the apartment. |

I suggest S5's for areas that sound is not an issue.
he should searching for not only a place where the sound is not an issue, he should find for a place where the temperature is not an issue too, dont forget that  btw about to reduce the noise, there is one thread talking about how to underclock the s5 here -> https://bitcointalk.org/index.php?topic=1151460.0 i know is not what are you searching for, but maybe reduce it a little bit will bring you a reduction of the noise, dunno. I think the easiest way to solve this is lower the speed of the fan. It depends on how cool air you can blow on the S5 but if you buy box fans and use that to push air through the S5's fin, you should be able to lower the fan by a huge amount even at 30c ambient. This work well since the box fan has a fairly high CFM but is pretty quiet because of how bit it is. The second thing is if you can feed it cool air, for example if its cold 8 months per year like it is here, you can just open your window and feed it cool air, assuming its not a window vulnerable to taking in water. Right now my fans are set to 38% and are thus quite bearable with under 60 dB for all of them combined. Even if you underclock and lower freq with original fans it's not what I would consider quiet (IE one I would want in a room I use much). Some have switched fans to much nicer and quieter ones that is really needed if you want more quiet not just bearable. Avalon 4.1's still are king as far as quiet miners that are not to old. But they do cost more to get and only from used market. At 2600 RPM i find them quiet enough. And soon i will be able to run them at the minimum, i think the firmware will let me run is 20% which should be about 1800 RPM. Which for me is very quiet. Can't hear them at all in the next room. But keep in mind that for 2600 and less rpm i need outdoor temp of 5-10c fed strait into them. They're running at 387.5hz though, i didnt try underclocking them as well. Temps are low too, 48c~ at 17c outdoor but 3000 RPM. I could probably lower them further but i like this target of 50c. |

Well, i wouldn't call it alive. And if its not alive, its um. Dead or... stillborn? I don't know, i'll let you pick I don't think the concept of XT's solution is bad, after they removed some of their unnecessary extra code. But i think there is a better way to go about solving the transaction limit. |

Escrowed for a S5 deal with cryptolance. Was very quick to reply all around the clock. It went very smooth, i'm happy with my first escrow experience. Would recommend!

So a strong correlation between the Hash Rate & the Error Rate, but seems to be having a greater effect on the Hash than I would expect? I guess No 1 does not like the cold. Would be instructive to drop the Frequency to 575MHz and see what that does to the Hash & Error Rate. Rich I guess i'll have to further my theory where its simply the volt control not being equal. It would be interesting to see whats the core voltage on the S7 of various performance. If it has poor volt control, this would result in not having a proper amount of current fed to the chip, it would explain why some miners show more HWE% and much less hashrate even if it is not proportional. This seem like the same thing/issue with when you try to clock a S5 to 400hz+, the hashrate drop even though the HWE% does not go up by that much. If you could raise the voltage of those S7 by a bit, the problem would probably go away, though maybe at worse efficiency. |

Well, after all discussions here, are the S7 is good thing to enforce the mining farm with? Sure, their efficiency is good (and it's definetely the best available for upper-home level miner for now), but what about their reliability?  I don't know, seem pretty hit and miss again. And the price is pretty hefty too. I think people that have acceptable electricity costs should stick with S5's and just let the S7 decrepit in price and prove itself first. Unless your electricity cost is too high, then you could get a S7 but at that electricity cost i'm not even sure you can ROI the S7 before the halving with such electricity cost. At which point i doubt they will be worth more in 6 months than what a S5 is worth now. An S5 is worth ~ $300 now. Your way off thinking an S7 will be worth $300 in 6 months. I am? Then how much do you think a S7 will be worth with the halving? The S7 will suddenly less efficient then than the S5 is efficient now. So how am i way off? The S7 is not only very overpriced right now, it is also not that efficient. Competitors have 0.15 and 0.06 efficiency chips. I don't see the S7 being worth much at all then, just nope. Don't worry, I'm sure bitmain has 0.06 and 0.15 chips too. We'll get those in a few months when they're done selling their old S7s. Thankfully i am not too worried, i always suspect such "conspiracy" to be the case. I'm just annoyed that they're selling the S7 for so much and people defending its value. I think at this pace, some home miner will be in for a pretty bad return on their investment with the halving. Bitmain already said their next stuff would be 16NM so its likely they already have a progress toward this. They might be waiting for a higher production capacity however, since producing chip toward the technological limit is always low yield. |

Unless YOU can buy a more efficient miner it doesn't matter what the self mining corps have. We will see in 6 months; Of course it matters. Its actually the other way around. Its not what *you* pay that decide the profitability of Bitcoin, its what *most* of the network pay their gh/$/day upkeep that does. Home miners is a minority and the profitability of S7 will go down regardless of if Bitmain release a S9 or not by then. Difficulty is not going to stop going up because home miner are no longer getting competitive hardware available and the halving won't stop from dropping the profitability of all miners just because *you* can't get a more profitable miner. This is a debate I have had in my mind more then one time. I have been home mining since 2012. Difficulty was once 25% per jump for an entire year. It is now around 2.5% for the last year. The true home miner has 1 thing going for him that the farms don't the ability to use the heat. So for 7 months a year my mining cost drops as I use the free heat. The biggest thing against a home miner is most homes are 200 amps which caps you at 100amps or so for mining even if you do three 30 amp 240 circuits You have 90 x 240 x .80 watts or 17 kwatts. so this would be 15 s-7's as a max that is 72 th 72 th earns .59btc a day when I was doing gpus and was using 6-7 kwatts back in 2012 I was earning 1 btc a day So in btc power cost we are losing. 17 kwatts gets .59btc 2015 using gear that spends .25 watts a gh 7 kwatts gets 1 btc 2012 using gear that spends 300 watts a gh so with gear that is 1200 x better 1 btc costs 28.8 times the power price factors into this 2012 price 10 bucks 2015 price 240 bucks the is 24 x but power is 28.8 x so The cost to get a coin is worse. more on this as the price for gear in 2012 was 22 x 350 =7k gpus and 3k in pc parts or 10k 15 s-7's cost = 15 x 1650 or 24750 so 2012 = 10k 2015 = 24.750k make it 25k so gear is 2.5x the price All this is killing home mining and all mining. once you factor all this in it is 3x more costly to get a coin in 2015 then in 2012. Not good at all or is btc undervalued and should be 720 usd not 240 usd? I'm fairly certain if the price raise by that much, there will just be more massive data center that get onlined and profitability will more or less be back to the same with the difficulty increase. After all, the profitability is decided by what the majority pay, not what we pay, so we're pretty much just being dragged along, whether you have 50A capacity or 200A capacity. For a home, you may have access to 90A 240V which is much better than my conservative 70A at 120V vs a max of 125A for my complete apartment. The difference between now's hardware and then's hardware (2012) is even if now it cost 2x more, it should be profitable for longer. But our real only advantage is as you say, we make use of the heat if we needed it either way. But there is a limit to that as its not like we need 10kW heating 24/7. So Home miners have it very hard right now, and very cheap electricity cost is needed. Like access to Hydro electricity or such. That way you can rush and buy all the S5 when the mass of home miner rush to the S7. As we expected many S5 has fallen down for sale with the S7's coming. |

please,somebody send me a 100 $ S7 coupon to user id : vortexz
Thank you in advance !
The coupon need to be sent to your email registered to Bitmain. And you may be able to get one cheap at the market place. I wouldn't hold your breath for a free one until giveaways next weeks. But good luck nontheless. |

If you got all the cables i'm interested in the 5 * 1300w evga! price please?
I believe that he wants to sell them all as a single lot. Which is too bad. I also would only be interested in the EVGA G2's. But even a lot of only the EVGA is more than i need sadly. It might interest someone around where OP live as a local pickup. |

I would agree in most cases. But for non-technical user coinbase with 2 factor is pretty good. Coinbase is different then many as they have that insurance. Read on their site to see what it covers.
But if you are a technical user who can properly keep private key yes it is better, as you have complete control. Assuming that you store it safely and properly.
I have to mostly agree with that point of view, but if you want to store serious about of BTC and you're "non-technical" you should hire someone technical to do it. If the amount is within acceptable losses for you, then sure. Coinbase as a convenient vault storage sound better than other online wallets. I don't think they can beat a 100% offline computer. One that has never touched the internet ever and has a secure backup copy somewhere within an encrypted usb key and or printed encrypted paper in a bank safety box. But then other than that, Coinbase sound good enough for most users. The idea of hiring someone to setup your BTC holdings is horrible. I don't care how much trust you have for a "non-technical" user do not hire someone to set up your private key and cold storage. You want it to be you eyes only or it defeats the whole reason of being cold. I'm not saying it's perfect for all users mainly technical and safe ones. But for someone who does not know how to use bitcoin properly coinbase forces you to not have a private key.... which is good if a user does not know what they are doing. I don't know, I just wouldn't trust an online wallet with more than 1 BTC. Any online wallet out there. And if you have to trust online wallets, I would choose 3 different ones and put 0.33 BTCs in each one of them, just to spread the risk. About someone securing your coins, yes this is terrible if it's not a person that you absolutely trust. Your brother, mother, father. If you don't know how to secure your bitcoins by yourself, you shouldn't own any. Also, to secure your coins is not that hard in my opinion. Setting up a wallet for Ethereum in the command line window, that was hard. Backing up the seed of your Electrum wallet by following simple instructions is not hard at all. Thats what i'm saying. I'm not saying someone should hold your coins for you, i'm saying you should have someone teach you to do it. Show you how to set it up. Its not that complicated. There should be no risk with having someone show you how to set it up unless you're completely clueless and somehow manage to hand over your BTC. Setting up an offline wallet isint that hard. And for Coinbase, i think its the least worse Online wallet. I wouldn't store significant amount of money there. A few BTC at most, in the vault, supposedly insured should do, however. |

10 to 20 BTC been good to be a long-term investment 20 years
10 BTC is around ~2400 USD which normally in U.S you can earn within a month (maybe more or maybe less) But if you think to retier with just a couple of thousands of dollars then i think that you are completely wrong. I think maybe 10k BTC would be enough to retire but that cost a fortune (millions of dollars) So you think that price of 1 BTC will be $240 in 20 years? Interesting! it will be four digits price for sure maybe even five digits but this is hardly achievable on my estimations Yes, I think so too. But the user above has implied that the price will be pretty much unchanged in 20 years. When you consider the inflation in the 20 next year's, this means that price will actually be 50% lower than today, if 1 BTC stays at the $240 level. This is hard imaginable to me. The US inflation has been very low lately. I think 0.2%~ per year in the last few years. Overall the US economy is fairly strong at the moment. But that can't last forever and even in the best case scenario, if the price stays at 240$~ it will mean a loss in buying power overall. So you'd be better off putting your investment in a 5% annual bank account or many other things than hold Bitcoin under these conditions. |

Well its kind of a no brainer, just get cheap S1/S3's and have the heat all thrown out that window. ROI should be very easy with free electricity. Try to go for 1 month ROI with S1's and 2-3 months ROI with S3's, not counting the PSU's. I'd recommend getting some nice EVGA G2 PSU's that will last a long time, as you upgrade your miners to better suit your electrical capacity. And good PSU's also may mean less hardware failure. Any other questions?  |

Bitcoin qt or bitcoin core is the most secured wallet as per bitcoin.org. They say only this wallet is deterministically created whereas other wallets are not even their from open source code.
Not only bitcoin core. Multibit HD, Electrum or coinbase or blockchain.info are the other wallets users trust and using. So, lot of options to choose our wallets. But do not forget to encrypt your wallet with a strong password. I'd stay away from blockchain.info right now. The recent attacks really show how shoddy their stuff is and people actually have had quite a bit of issues with their API for a fair bit of time now. And in term of security feature, i think the best would be Armory, since that lets you more easily sign transaction with your offline cold storage computer that never has and never will touch the internet. |

MLM = multi level marketing. the bitcoin blockchain has no affiliate/marketing built in, hence no multi or single level marketing.
It can be argued that since bitcoin is "ethereal" its only purpose is is to buy more and enrich the first buyers. But if this is the case, then the same logic can be applied to fiat, in which case its much worse, so their MLM argument fails badly... That sound like improper application of logic, since Bitcoin can be mined and thus reward is obtainable without putting money in a marketing ploy that goes strait in someone's spending cash. It's true that early adopter that held their Bitcoin have became big winner by now, but that's not what a MLM is. I'd say such is the natural way of the economy. You either have a vision or you don't. |
