1941  Bitcoin / Mining speculation / Re: how will 'micro miners' like 21 chips and bitfury lightbulbs work? on: February 25, 2016, 05:42:57 AM
As with most mining gear, the primary beneficiary of these gadgets will be the sellers them selves (i.e. Bitfury and 21 Inc.). Buyers won't make a dime on them. I'll furthermore suggest that 21 Inc did their "miner" as much to help them garner $116M in Venture Capital (VC) money. Hard to know what all they did with that money, but I'll bet it was a small sliver that went into the Raspberry Pi "Bitcoin Processor". They don't actually call it a "miner" in the classic sense.

I wonder if either one will do as well, or as poorly, as the Antminer R1.

The R1 made a decent U3 controller after crazy guy's firmware.   I think the RPI kit was priced where they knew they would not have to make many.  I know I bought a R1 to play with.  But the 400 dollar price tag on 21 Inc... made me stay away.  It did give them a item they could show off to investors... it no doubt helped in that area.

Everyone is real secretive they might have a great idea to do with all the money they have in hand.   But we won't know till they launch it public or it leaks.   And leaks don't seem to happen to much anymore NDA's are pretty tough.   
1942  Bitcoin / Hardware / Re: Antminer S5 in a hot Texas garage? on: February 25, 2016, 05:31:30 AM
I ran about 7KW of gear in my garage last summer.  Temps hit 115 degrees or so regularly in the peak of the summer.  I did have to downclock the couple S5s I had to around 275-300mhz if I remember right to keep them cool enough with the fan at full fan speed (stock fan).  Afterwards when it got cold again one S5 was never able to OC very well without going xxx on one blade.  Oh well!

S1/S3 were never as temp sensitive, and the SP20 could be downvolted/downclocked to survive just fine.
 

What did you do for cooling?  I know some push some gear pretty hard but ambient of 115 degrees is getting up there.   Yes some miners can run in much hotter environment's then they advertise. 

But I sure would not risk it.   S3's were tanks I have heard of very hot temps.  Even still a S3 and S5 are two completely different beats.
1943  Bitcoin / Mining speculation / Re: Mining and the Halving on: February 25, 2016, 02:48:30 AM
We're mining ourselves to oblivion.Even when quantum computing comes out, it wont be much help as algorithms like sha256 just dont work as well. Efficiency will eventually peak and we'll start seeing a transition from regular mining to solar and wind powered mining. Efficiency will peak eventually and when that happens, we'll start turning to "free" power sources and hashrate will be all over the place.

I don't think were going to hit quantum computers in near future on mining.  Asics do one thing great... they are designed for this.  They will continue to be lower NM and perfect the lower NM.   It just makes sense.

Free power is kinda a different thing as they don't need the latest and greatest.  The newest gear traditionally is in a place that pay's a little bit for gear.  If you have a few cent electricity.... you are lucky and can profit on older gear.
1944  Bitcoin / Mining speculation / Re: Rent my hash power on: February 25, 2016, 02:45:53 AM
What is your mining hashrate? Most of the rig rental sites are free to register but charges a small fee.
really low... 730kh/s (for scrypt)

that is very low hash rate. So it does not make any difference if you use Nicehash or not. If that is GPU, better mine other algorithms.

And you can do this through nicehash.  You are better off going over there and selling though it's great site.  You are really not going to find a buyer for a small amount of GPU power though here (i don't think).

With going through nicehash the buyer also knows they for sure get the hash for X amount of time.  It kinda acts as a escrow.

Payment post count has been reset to 0 and myself also with no payment for posts made but tx shows has gone to bit-x account but I have checked bit x account and nothing shown yet https://blockchain.info/fr/tx/d8d8f43ed4146102e4e1eb4d7251f54c21f3571f4713360f33c43c73e76bdf4b shows paid so maybe problems on bit-x exchange?

No the hot wallet is filled.  So it is not a issue on funding or Bit-X side.  It is something with payment bot it reset us and did not send any payments.  So not sure what happened.

I know it will be fixed.  Hopefully soon, but it is the bot that I think needs to be told to send out payments for the period.
1946  Other / Beginners & Help / Re: Can i Mine with a dual core CPU? on: February 24, 2016, 08:46:26 PM

For most altcoin, it is not profitable to mine with CPU. Examples are Dash, Monro and Ethereum.

Ethereum could be an exception. It is mineable with CPU and you can make very little profit now.
Don't even start with Ehereum, it is not a good altcoin to mine. First of all it is not hard capped coin.
Than means developers can increase number of coins on a whim in the future - if they decide that there are not enough coins in circulation.

Everyone is years to late.  I don't care how good of CPU coin it is at this point.  Show me a equation where you not only make more then electricity but ROI on a cpu... I don't see anyone ROI'ing on cpu.

It's a lost cause at this point compared to expenses.
1947  Other / Beginners & Help / Re: Who gets the miners fee? on: February 24, 2016, 08:44:36 PM

 I don't know if it is my luck or general but I send around 40 cents to a dice website and paid 4 cents for it to go and right now it has been 3 hours or so and it hasn't arrived. 0.0001 was default fee that I 'should' pay if I want everything to be fast , I paid the 0.0001 that is basically taken from me by force (if I don't pay it it may take days!) and still takes more then 3 hours?

 Bitcoin transactions becoming more and more like western union with miners fee.

I would guess your dealing with a lot of dust type payments.  When your talking about lot's of transactioons and amount is for cent's... yes dust is not so great.

I look at sending in a larger sense though as I don't gamble or do really any tiny payment's that I can think of.  Gambling I don't see the fun in on most of it.   
1948  Other / Meta / Re: Stopping gift card money laundering on: February 24, 2016, 08:41:14 PM
I think so too. But if you really think about it. This just cant be helped. People would almost always find away to get things their way. Even if that would mean going through the illegal stuff.
True but tagging them would at least make it more difficult to them and/or slow their illegal business and/or at least push their business to another site, protecting somehow bitcoin's reputation.



Sadly I think this is a moot point as some are obviously ok with buying carded CG... which is honestly sad.  It should catch up with them eventually companies do track addresses of where carded items were sent to.
I don't think it's a moot point. If most non-GC-seller trusted users agree it should be stopped then we can reach an agreement and try to stop them. Of course not everyone will agree.

I applaud you if you and others can get the carded GC's out of here somehow.  My meaning was it is a moot point as there are sadly obviously buyers out there for it.  Willing to take a cheap GC knowing it's carded.   

But if you are able to get even some of them off the market I do think it is a good cause.   It's not something we want people to associate forum with.
1949  Bitcoin / Mining support / Re: I have some questions about mining on: February 24, 2016, 08:35:20 PM
I'm thinking about starting mining,
and I think about using  a vps. I would love if some one who have already tried it help me a bit
the idea is to buy like 3 or more vpss and install miner in them !! would that be profitable regarding there cost?
any stats?

I started mining and I'm looking at a screen that's calculating , I hit start and in just watching it .
What do I do next , what do I expect to do after a while .

Nothing. The miner output is processed and submitted to the pool youre mining to. Your shares are calculated by the pool which will share the earnings with you. But if you're not mining on specialized hardware strictly for Bitcoin mining, you will not earn one cent.

You just let Cgminer run forever. Until its not longer profitable for you to do so i suppose.

It would not be cgminer with VPS's.   Most likely it's cpuminer you run, but Virosa is right it just is not worth it.  VPS's even if very expensive chances are can make more doing other things than mining CPU coins.

The day's of CPU mining are just over.   Might you make a little if "free" .... yes but were talking about very small amounts.  Not enough to interest most people.  VPS mining did not last very long.... it was a really fun type of mining but did not last long at all.
ahh. the good old days. I remember those. I used to run with a old pentium m cpu but it kept overheating. I probably only mined 3-4 bitcoin from that, and I blew it on gambling. Never doing THAT again  Smiley

I stick with VPS minining was one of the funnest and fastest types of mining there were.   I mean at one point of time it was profitable to have a EC2 instance with nice VPS.  But miners went so fast it did not stay profitable for long.  CPU coins difficulty skyrocketed with VPS usage.  I can't even remember the name of the alt coin's I mined at the time it was so quick.

Now day's even with a free VPS you are talking about very small gains with cpu mining.   So quite the show of how quick we can go through technology.

Thanks for the reply I managed to get everything back up and going again not long after posting the call for help but I appreciate the help regardless even though I sold not hours after restoring functionality.

Maybe mine was a "runt" or just a slightly less than average performer but if I didn't hit 11.9v. or higher on the GUI the damned thing wouldn't even come close to advertised speeds in fact at 11.5 and 11.6 I would routinely be averaging 2700GH/s that's way shy of what I was expecting.

Bought on ebay for 700 sold on ebay 690 maybe I got a "dud" but I found it to be far too high maintenance for my style.



If it's only getting 2.7T... you would have been better off going against who you bought from vs selling.  If someone receives a miner like that under paypal there is a HUGE  chance it's going to be returned.

Did you warn in auction it was getting 2.7T speed?  I wonder with red and speed.... if you possibly bought from someone who overvolted it and killed 1/2 the hashing.

no  some other issue is the problem.  I killed a board and dropped to 1.4- 1.7 th  2.7 is too high for 1 board.

Still I hope he listed it as a 2.7T or that thing is going to be coming back.  It does not matter what settings on ebay paypal has a pretty hard side with buyer.

Did you know paypal has a "changed mind" option now... it's getting crazy I think.   They wanted the item at time of order but don't after time with it, and nothing wrong.  Crazy ebay and paypal...
1951  Bitcoin / Mining speculation / Re: Is there any profit? on: February 24, 2016, 08:24:40 PM
Where do you get those prices from!?? In the EU an s3 used costs something like 300usd!!!

Lutzov: I ser the point of course. Profits trend to get lower. And comprensive about that.
I start to understand that, this is a question of strategy, balancing with care the costs and winnings.

EU Vat's kill almost any deal on mining gear.  Just so high it adds to prices and makes your miners higher.  There are some that lie on VAT... but personally fraud is not something I would go for.

You are better off with a hosting center.  I will be cheaper than you electricity you pay, and also can find one with no/cheap vat.  So gear is cheaper and makes a huge difference all the way around.

Maybe i could sell him some S5's and ship them to Allinvain xD
I dont know what hosting price he could get but it would definitively be much better than buying one in Europe and running it. Afaik getting a miner there is super expensive and the electricity is prohibitive.

Honestly you would be doing him a favor long term getting it in hosting center.  EU is just a hard place for miners.  High VAT's tacked onto miner costs.   Some countries have rediclous VAT/Import taxes.  And it normally is not cheap electricity in EU.

But on S5 need to have pretty cheap electricity price.  I sold all my last gen gear as I made more off sale vs mining it.   But if you have cheap electricity you should be in for some deals as last gen just get's cheaper.

Price a slight positive going at 423 right now and heading up.

Maybe the crooked farm in China getting busted is a true story.

But remember the 80 to 120ph   is out there power down and unless it was destroyed it could all come back in as little as one day.

I personally won't believe it unless more then some twitter talk happens.    If they were caught... they still have gear that I would imagine they would be trying to get somewhere else.

I just think it sounds like to good of news to be true.   And even if it was true long term I we would need to know if it's something they pay fines, or jail.  And either way they would be trying to get that gear somewhere else I think if was true.  

A little could be batch 11 shipping.  Don't know if we know how big this batch is really.
1953  Bitcoin / Hardware / Re: ANTMINER U3 Discussion and Support Thread on: February 24, 2016, 08:15:41 PM
is a real U3 antminer or a fake one?

Looks like someone is trying to sell "cloud mining" via a U3 that they host somewhere else?  Looks sketchy as hell to me.  U3 hash isn't worth anything unless you have one for fun, and even then they are not much fun because they always have problems and you basically have to buy an R1 an install custom firmware to get them to work reliably.

I could not tell they mention virtual... I could not tell if virtual miner or saying BTC is virtual.  I tried my best through google translate.  They do mention shipping ... so part of it sounds like shipping a miner.  Other part virtual... it is either sketchy or my inability to read that language.
1954  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs on: February 24, 2016, 08:10:19 PM
Mr. Spondoolies,
Let me help out.  The way to raise money is to build a miner and sell it.  I am pretty sure it was working for you guys before, may I suggest you get back to what worked.

That was soooo 2014,get with the times man  Roll Eyes

No money in the "home" miner scene dude!!!!! We are too needy,like "customer service",don't need but 1 person for that 1 "corporate" customer  Grin

The SP50 which they seem to still intend on producing is not a home miner.  Making miners doesn't necessarily have to mean for home use. Even the S7 isn't much of a home miner IMHO.  I wish we could know more about what SP-Tech actually intends on doing moving forward from them instead of the usual forum bullshit speculation.

I would love to see more then a rendering.  They have been pretty quiet as far as miners.  I'm still not sure what to think about it.   I thought they would be trying to race against bitfury.  If they are they are doing it in secret.... which I think would be kinda hard with financials and so much info public.

Even thought that one chart does not show them in competition with bitfury.    I think they most definitely are in a competition  against them.    Bitfury if they hit spec on chips... going to be hard to beat.
1955  Bitcoin / Hardware / Re: Examples and pictures of <100$ mining rigs on: February 24, 2016, 08:07:55 PM
Looks like to me EU has more stickminers (just looking on amazon with their fancy little 8+ gh bitfury sticks). I kind of wish I lived in the EU now.. it must be a great place for (some) stickminers. Here in the US all you have are gekkos, overpriced bitfury sticks, overpriced antminer sticks, and overpriced block erupter sticks.

I ordered from the EU dealer on compacs he was very nice.  They are higher in the EU.   But he was great I wanted one in US as I had collected a set of compacs.  He got it to me. 

Stickminers if your going with anything else then Compacs it really does not make much sense.  And know that you likely will not ROI they are for fun and lotto mining.

What I would do is try to find a deal on a S3 don't know if sub 100.... but they are losing value.  For the money a S3 in that area.... is what I would look for.  And you would have to have VERY cheap electricity.
1956  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: February 24, 2016, 08:04:36 PM
Does Bitmain have the NEW S9 fully developed and installed in their Farm?

When would they be releasing the S9 to the public?

Intriguing thoughts! 

What are your thoughts? 

BITMAIN, you are welcome to chime in.

im very sure they will release kind of s7+ first... maybe 10THs @ ~2000w to sell more BM1385īs

IMO they will release S8/S9 only when an competitioner like Bitfury is selling more efficient Chips.

I doubt we see a S8.  I think day's of even numbers with all in one setup's are done.  I could be wrong but they have stayed away for a while.  I think they have mastered shipping costs staying with odd numbers.

They have been VERY quiet.  When S7 was coming out there was all kinds of rumors we knew with S5+ some big things were changing.  So far we just have not seen that.  That is no way means they don't have it ready to go, but they have had 0 leaks of info yet.
1957  Bitcoin / Hardware / Re: Antminer S5 in a hot Texas garage? on: February 24, 2016, 07:58:46 PM
So I'm noticing the prices of the S3s and S5s dropping significantly.  I have 2 S3s and was thinking about adding an S5, but I have a few questions.

1. The S5 is as loud as a small vacuum, correct?

2. I live in Texas where it's easily 100-105F every day from June-Sept/Oct and never drops below 80F at night during the summer.  I would want to put the S5 in the garage, which gets even hotter.  Would this be ok or would the S5 not be able to operate at such temps??

The S5 is hot and loud.   Might look and see if you can find a DB rating, but "small vacuum" is hard to quantify that into a number.

Would I mine in 100F .... no I think heat is going to be a pain unless you have some really good cooling.   Add a few S5's to a area that is already 100+ F ... .you are getting very hot.

If the area is well aerated or open-ish, he might be able to get away with it by adding a second fan, and maybe he could also try to use box fans to blow air through transversely. Its hard to tell what will really do it, considering how the heatsink just throw air everywhere.

The print modded enclosure would probably also do it. If not, underclock.. but that would kinda suck. But if all else fail, its a good failsafe.

If your cool air you bring in with fans is 100F + .... its going to be hard.  A lot are right about under clock and lots of air.  But still sounds expensive to cool down and your getting under clocked rates.

Most likely going to a hosting center would make more sense.   If I was dealing with 100F+ I know I would be looking for hosting center and run gear not under clocked.
Yeah at this heat you're going to be pouring a lot more money in to keep things cool then what you will be making. If you want to mine for fun, set up some usb sticks and sell the S5 to buy them.

And I have had those hot summer day's.  I ran all though last summer.  Normally 70-80ish.... i had to resort to a LOT of CFM's of air it varied but always was around 12k+ watts worth of gear.  The day's it hit 90... I hated it and watched the heck out of my gear luckily it was a "mild" summer.

But if your talking lot's of gear you can see how I struggled and anwser was more CFM's, got 2 much bigger fan's then I thought I would need.   And eventually put in a professional gable fan as regular home gable fan's even higher end was not putting enough exhaust out. - https://bitcointalk.org/index.php?topic=1020826.0

And it's hard on your fan's even to run that long I had 1 of my 2 big fan's end up failing luckily within warranty.   But it happened during winter.... and lowes is very seasonal.  I ended up trading one of them in for a 12k CFM fan that pushes a heck of a lot of air.   I can tell anyone out there winter is much funner then summer mining.
1958  Other / Beginners & Help / Re: Hacking on: February 24, 2016, 05:32:58 PM
If you're serious as fuck about your bitcoins, consider a hardware wallet like trezor. Paper wallets can always be lost or drenched in water (yup, happened to me before). Hardware wallets are pretty strong and have lasted me a year or two. I plan to buy two hardware wallets soon in fact

WTF, drop it in water?

How about making multiple copies of it, perhaps writing it down on a laminated paper with a market to be water proof.

If you keep it on a small note paper somewhere in the house then of course it gets messed up.

I agree when you make the paper wallet you should not make 1 print only of it.  It would be crazy if you did to have it in a area with water around it.  When you store safely you would be smart to have at least a copy always stored away.

I do like hardware wallets more and more.  Also 2nd factor devices.  I see these becoming more and more popular in future.  Which is likely a very good thing.
1959  Other / Meta / Re: Stopping gift card money laundering on: February 24, 2016, 05:22:33 PM
Since I myself sell gift cards, I wouldn't agree with banning the sale of git cards on the forum. However, there are some obvious users who trade illegal gift cards as well as keys that are bought from stolen credit cards and they sell it at 20-25% face value. I would like that it should stop but still there is no way to prove they are illegit unless the websites are contacted and informed about the same. Also, there are many members who buy these illegally obtained gift cards. Don't get what they get out of it.

I don't agree that it will hurt bitcoins as mainly CC's are used for the purchase of these gift cards and not bitcoins. Don't get what's hurting bitcoins in all this.

I think the discount is a strong way of detecting these carded gift cards.  When you see GiftCards at 75 percent... there is a reason on most there are very few people are normally willing to let go for 3/4 of value.  Another good way is asking to see receipt of paying with cash... but arguably this could be defeated.     

Sadly I think this is a moot point as some are obviously ok with buying carded CG... which is honestly sad.  It should catch up with them eventually companies do track addresses of where carded items were sent to.

Not the first time i see this.

As Notlist3d said, there is nothing to worry about!

Happy mining! Grin

The only thing I would love to see if anyone ever finds it is what exactley what the equation does that get's to negative.   It does not hurt anything at all as far as hashing but it would make sense if that equation with errors is making it look better on HW errors then it really does. 

But not sure as it does seem to heavily be related to amount of day's.   And again it's hard to get to mad when a miner runs for a month that is normally a pretty happy thing.
