Better to buy 1155GH/s from Hashnest www.hashnest.comAntminer S5 Power: 0.51w/GHS Maintenance Fee:$0.001175/GHS/Day Then you see yourself, is S5 profitable or not. I couldn't understand that site plus apart from bitmain, I am not going to any coinflare-slowed website.

I actually have a serious point to make. I only discovered bitcoin three months ago, but I have spent many hours since reading a huge amount on the subject. I've done my very best to look at things objectively, and have listened to arguments from both sides. I have arrived at the conclusion that cryptocurrencies will, with absolute certainty, play a huge role in all our futures. It may not be with bitcoin- but it's looking increasingly likely that it will be with the crazy network effects, huge existing mining pool, and cryptocurrency 2.0 apps being built on top of it (counterparty for example).
Given the above, a bitcoin market cap of above $1trn is not only not unlikely, it seems to me that it's almost inevitable. So I have invested 75% of my life savings into it, and intend to hold it for years without spending a single satoshi. BUT WHY ISN'T EVERYONE ELSE DOING THE SAME!? Am I missing something? I can't help but think that I must be- the notion that I am right, and almost everyone else is wrong seems too good to be true.
I'm aware of the various cognitive biases which may be affecting my judgement, and have been careful not to forget the idea that 'The moment we want to believe something, we suddenly see all the arguments for it, and become blind to the arguments against it.' Yet even considering all these things, I still arrive at the inescapable conclusion that bitcoin is headed to very, very green pastures.
So I suppose the point of this post is to ask- am I missing something? Have I underestimated the chances of something going severely wrong, such as a major code fail? Could crypto simply 'fall out of fashion' and everyone goes back to fiat?
Depending on your age and risk taking profile 75% would be excessive or not. My formula is: subtract your age from 100, then divide the remainder by a factor of 3=% to invest in bitcoin. [(100-A)/3]x100=% to invest So for a newborn baby that got some cash (from parents and grandparents): 33% For 20 year old it would be 24% For 50 year old 17% Apart from that, the opposition from the establishment is the most possible negative. They already got their money in $$. Why switch over? We can hope that bitcoin will develop slowly and they will switch over during 2-3 decades. Then, it might work.

Remember, they weren't mining or even connected to the pool at this point. The temps just started rising past 80c without shutting down. The firmware seems not to shut the rig down when it is over 80c. That really needs to be fixed.
Well that goes against everything I've tested, pulled the ethernet and nothing exciting happens. And I've previously tested the 80C limit, it 'freezes' and stops mining. I agree - it doesn't make sense. My S3's properly honored that 80C safety shutoff. But on my pair of S5's, it does not shutoff over 80C. BTW, the miners really do heat up and it's not just an errant report from the firmware. A few weeks ago when Ghash went down, my Nicehash limit for return value wasn't met and so it stopped hashing (no rollover) and I did catch this screenshot. There is a conflict in that screenshot, a fan speed of 3600 RPM yet a high temp. At this point I'm leaning towards it reporting silly temperatures rather than reaching silly temperatures. On a 200W load, even with a 1000 RPM fan it should still be okay. Heatsink temps of 75C over heatsink temps of 50C provides DOUBLE the heat removal in a 25C ambient. Ah! I think you have landed on an issue. Thank you. The physical truth is, at the time of the screenshot, the fan was not at a high rpm (judging from startup/reboot speeds it was in the 300 to 500 rpm range); and the heat sink fins were too hot to keep my fingers on. I believe the heat reported, but not the fan speed. But that still makes me wonder why the 80c safety didn't kick in. This also happened about 3-4 weeks before this screenshot. That time it reported 106C, but I didn't grab a screenshot, I was freaked out by the high temp and hurried to power down and move air over them with a box fan. So the bits of information we have: a) Status reported high temps b) Heatsinks were too hot to keep fingers on are ~55C for aluminium, which puts chip temps not much higher. c) Status reported high fan d) Fan was low in reality e) Status did not respond to these 'high' temps f) Status previously showed 110C, but S5 still works. From the very last one alone we could conclude that its a display / calculation issue, and the chips aren't reaching the temperature its displaying and / or the measurement isn't even what its displaying. If that type of temp sensor was 110C, the chips would have been way past the "melt into goop" region. So I just ran a test, by killing my internet. Very interesting to watch. The fans spin slow (at an inaudible level). The GUI seems to be stuck with the last valid stats from while hashing. I'm getting the feeling that the GUI only reports when the machine is actually hashing. I watched the temps of the heatsinks rise by ~8C during the lull of no hashing (with an infrared thermometer). After connecting the internet, and the miners quit beeping, then the GUI would report an updated status. After the beeping stopped (internet connected) the fans also did spin up again (full rpm). After restarting the internet, 1 miner had blades at 96C & 83C reported. It would not start hashing again, without a reboot. The other miner had blades at 93C & 78C reported. Based on my infrared temp readings, both heatsinks were within 1C of each other. This miner did start hashing again on its own, after restarting my internet connection. Here's some absolutes I know after my test of an internet failure: 1) fan speed drop to nothing and the temperature rises during the failure 2) the windows GUI does not get updated status from the miner during the failure So why don't the fans stay up to speed to keep the chips cooling during an internet failure? Beyond that, I only have assumptions (though educated guesses, they are still guesses). It's as though the system is not monitoring its own temps during the internet failure, to adjust fan speed and maintain an operating temperature. If I was a manufacturer, or had a miner that I didn't have to pay for, I would have let the my internet failure run for more than the 3 or 4 minutes I dared to (watching the temps go up). I would be interested to see how high the temps would really go after 30 minutes or more (but not on my out-of-pocket equipment). as i posted before, most important is whether it still uses the same power as before the internet failure-could be easily checked with a kill-a-watt. If it does, then it would be very dangerous. If not, than it is just residual heat (as chips are NOT working anymore) and maybe metal sinks will dissipate the remaining heat safely, even if they heat up to 90C intermittently. Using my S5, as soon as internet drops, power usage also drops to very low (maybe 20w). Whether some other individual miners don't do the same (drop in power usage) is essential to know. i agree that they should have program it to rotate fans for a couple of minutes after the internet blackout.

can anybody tell me why one of the ASICs always is so hot? ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2F43MGqmKm.png%3F1&t=663&c=WfZt2koO1w-QjQ) Is it because of the hot air from the others? If you set on auto, SP20 will adjust power usage upwards until one of ASICs hit 115C at the lowest fan. Then, it just keeps the fan at the speed where no ASICS are above 115, but yeah, it is one asic that probably gets hot air from others.

try to imagine yourself in November of 2011 and apply the same logic, considering that price was low, halving was coming, miners were unprofitable, bitcoin was in the downtrend. How did that situation predicted the next 24 mo with bitcoin going from $2 to $1160? It didn't. I am not saying that we will have the same spurt, just that it is not really predictable.
I would agree with you that it seems that in bitcoin soup some ingredient is currently missing and it is getting a bit boring lately, unfortunately. All news are either about someone stealing bitcoin or about regulation.

Don't mean to revive this thread but have a similar question. Considering the SP20 or the S5. If I wanted to max wattage consumption at 450-550 watts which would get me the most speed at an underclock? I don't know if 450W is even possible on SP20. 550W is possible with a good PSU on both Sp20 and S5 with similar speedI'd like to keep temps under 46c and the noise at about the same of a stock s3+. It does not work the same way as on S3 as far as temp are concerned. SP20 shows exhaust temp (less than 70-75 is OK) and actual chip temp, for which 85-115C is OK; for S5 the sensor shows some temp, which is roughly at least 20-25C less than actual chip temp-with temp less than 65C being OK, they don't need to be 46CAlso, can either of these be load balanced to divide up the hashing power and mine on 2-3 pools at the same time? not sure, but here is one link:https://bitcointalk.org/index.php?topic=966799.0see ^^^^ Well I'm concerned about temp because the 45c that my S3+ runs at heats my bedroom to the point where I need to keep my door opened and close off the heating vent to the room. So if both run significantly hotter then both are a no go. you simply can't have either of these machines (unmodified) in the bedroom as they are too loud for this. You can mod S5 with a couple of low noise fans (there are gazillion of posts about this) PLUS use it at 300 mhz-should be ok for ~1000GH.

I'm wondering how high that temperature could of went to.
80c. What fans you running? All stock. And I just read other's are having the same problem. Temps over 80c and keep climbing. Not good. If I wasn't home I'd have two toasters. Remember, they weren't mining or even connected to the pool at this point. The temps just started rising past 80c without shutting down. The firmware seems not to shut the rig down when it is over 80c. That really needs to be fixed. Well that goes against everything I've tested, pulled the ethernet and nothing exciting happens. And I've previously tested the 80C limit, it 'freezes' and stops mining. It doesn't need to be mining. Once the pool drops or connection drops, the fan slows down and the temps keep rising. I can keep my iR temp sensor pointed at a certain spot on one of the fins and it will gradually get hotter and hotter. interesting.. I haven't seen anything like this, usually pool just switches over, unless it is nice/westhash, which never worked properly for me on S5. Use the power (watt) meter. If you see that power usage drops, then nothing to worry about. If, however, it is still drawing regular power after pool disconnect or connection disconnect, then you have a problem miner. Solution: situate an external fan behind the miner (I use Vornado). It helps with air citculation.

the PSU they already have, they don't have a psu, they buy in bulk what they need calculating an 4th miner put in function 2 months ago is ~600$ They get those psu directly, they are custom made for them and they are probably pretty cheap as a 1400w server psu can be individually bought at ~200$ http://www.newegg.com/Product/Product.aspx?Item=N82E16817377050 To get 4TH we talking a lot more power and standard home outlets don't allow over 1800w so unless this is JUST for data centers we won't see a 2kw home miner s6. 2x 1200 watt server psu's = 2400 watts easy peasy .4 watts a gh = 6000gh done if they want to do it. So it would essentially be 2 3000Gh machines in one case, that and no home miner would be able to run it. Plenty of home miners could run that. All you need is one 20A/240V outlet. Perhaps you mean " A home miner that is not willing to spend a dime upgrading their homes electrical system cannot run it." 240v is NOT considered home mining equipment. "Home mining" means just what it sounds like. Equipment that can be run easily in a home environment. Modifying your home electrical isn't an option for most. isnt the washer and dryer connection a 240v connection ? yes (+electrical oven), but try to convince your lady to use these for mining ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Poland, eh? Would you mind contacting those who replied and asking them for his address? You could offer them some money for it if they won't give it up, which I'll give you either with BTC or PayPal. I happen to know some unpleasant people in Poland, and I'd be up for taking a trip.
Thanks for your help so far guys, much appreciated!
Of course you can't rule out the possibility of a hacked or sold account. The account is registered since 2013. There's a huge market for ebay seller accounts. Many sellers make them and after a few feedbacks and increase in limits the accounts are sold. Check these forums http://www.aspkin.com/forums/ebay-accounts-sale/. And there are many others. Even here I saw ebay accounts for sale. I don't see how ebay account selling can posssibly work since it is associated with a specific name, address, bank account AND credit card. It would be idiotic for someone to sell their own info, so i can't imagine someone sane doing it, unless they sell stolen ebay credentials, but then it is a felony subject to prosecution.

Looking at these day-to-day gyrations the conclusion is inevitable that bitcoin is still far away from being an investable asset for most people, let alone a unit of the account. However, by the time it would be, almost all appreciation would already occur. The dilemma is whether to take risk now when it goes up and down 10% a day, or later, when it will be safer, but with a limited appreciation potential.
What if I told you that it might *never* be a good unit of account, and that that wouldn't be a problem? Is gold a good unit of account? Speaking of which, is gold an invest-able asset for most people? Fine. I am a bit tired of "whales" sinking the proverbial boat. Re gold-people could at least invest in gold ETF. I heard a lot of verbiage in the last 12 mo, but don't see significant improvements in bitcoin economy, especially in the EASE of use.

Think of Amazon and how their changes their prices every few minutes, only the other week I ordered something then it dropped $5. I'm not entitled to compensation. And its not a lottery, the price you see is the price you pay should you choose to buy. Customers were complaining the price was too high, and so it was lowered. If we all tried to set a price at once or kept it level or moved it up and down willy nilly then we'd get nowhere. 467,149 cooks spoil the broth.
Last week demonstrated the Bitmain price to be a lottery for sure, the variable being which day/hour you purchase! I've ordered many an item from Amazon, and the price variation is very small, though admittedly fun to shoot for the low. $50 out of $420 isn't small! Multiply by two and it's a major hit. Purchase by any other means at any mainstreet store, and you'd receive a refund for the difference! Of course, by your opinion, Bitmain should be exempt (must be nice to have your financial resources). amazon and others show you what they want YOU to see, and believe me, so many of us are overpaying... Example#1: I was shopping on AMZN for turbotax home (because Intuit crippled Deluxe). price was $79 one day, then $80.84 once I "searched" twice for the same term-I guess they thought that I am hooked..I skipped. Same day from another computer-$48. Amazon is trying to make you pay extra ALL the time and they have lots of tools. example#2: Every freaking time in the years past when I tried to buy an airplane ticket, in the last minute expedia tried to say that they misteriously run out of this specific ticket/price-would you like to pay $10 more. I ALWAYS canceled their "enhanced" ticket in such cases, so they ask less recently, but someone is either too gullable or don't care-so they continue.

I think that people need a situation with a healthy competition, otherwise it all comes to bickering on price. I also think that a 5Th 1000w machine at a reasonable price would be nice (Or 6th at 1200w). A machine that does not produce more than 60-65db of noise.

@phillipma1957: Sent you a PM for the last S5 you have hosted with Lee.
sorry sold it about 15 minutes ago. @ lee I sold all four of my miners Nightshiftgirl first sale HerbPean second sale jmumich third sale no141 fourth sale All 4 s-5 had hosting paid until march 20 please transfer all four to them. Now I need to find some one to tear down and rebuild my chimney. No more hosted and I sold most of my coins. Sucks ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) Yeah It does. I have Been in this house since 1992. I have had the original chimney repaired 4 times. No more repairs I want a new one. It goes inside the home from the furnace to the roof and is next to the bedroom. So when I really thought about it leaking water into the home for the fourth time! I started thinking maybe it could leak furnace gas into my bedroom. So this time I spend enough for a total replacement. OT, but the quality of construction where I live looks atrocious (at least to my eyes). Expensive houses built of nothing but thin pressure-treated wood chips. Sometimes after rain i see all these panels visibly bending, but then they go into a house as if nothing happened. I am not a specialist, so maybe this is a false concern.
