Electricites

Rule #1.
Do NOT overload circuits.



Here in civilisation, we have real electricity.  240V with 30A per circuit, with most houses having a minimum of two circuits.  The houses here have 100A supplies, which is 24kW.  Good luck overloading with miners.

Yes but look what it's done to your teeth!

I dunno I am confused how my 200A 240V service to my house is a "problem" and I'm in the US. 

Seems pretty standard where I am...

Tell him NO and use join.me instead.  Thats a legit web-based version and he would have to "request control" and as long as you don't say YES you should be fine.

What wallet do you use?  There of course is the *sign* thing...

Starting on July 1, 3th/s will NEVER produce $13200 in bitcoin without crazy bitcoin appreciation (To 3-4k).

LOL @ "crazy bitcoin appreciation"

Umm HELLO, bitcoin HAS that potential!  It HAS done that repeatedly!  (think $26 fall to $5, $270 fall to $80, now $1200 fall to $600 ... guess what happens NEXT IN THIS CYCLE?! - $4K IS very realistic...)

Everyone buying original KnC units only made money because bitcoin appreciated a bunch in the first place!

I just remember with Avalons the consensus was those ASICS would "not be profitable above 2 billion difficulty" around the time they were purchased.  Umm we are over 2 billion today, do you think any of those Avalons have been shutoff?   LOL

Back on topic a little, I think Cointerra deserves a little credit for what seems like a pretty clean shipment of December units (at least in the US - I would like to hear from customers outside the US too). By the sounds of it they shipped many people's units on Monday, and most units arrived at their destination on Wednesday (2 day UPS). Everyone's unit *appears* to be operating at 1.6 TH/s, 1.55 pool-side.

I believe I was late in the December queue, but received my unit yesterday (Wednesday, Feb. 12th). It took one day between "Preparing to ship" and "Shipping". It took 3 days in between the "Preparing to ship" and actually arriving. The big question is - are there any December orders that have not received their unit yet?

Don't know a single non US customer which has received a unit yet, regardless of order position

None of my clients have. Dec-Jan orders all around.

Credit for Huh

Its mid FEB.  And DEC units are barely out the door...  (see:  bobsag3 who represents many hosted customers & international feedback...)

So what's the answer to if ordering today, when does it ship?

I think bitmain, sushi, and greaterninja are out of stock for the 1.45btc price...  might as well wait for the next drop  Wink
126  Economy / Computer hardware / Re: WTB: Power Supply 900W+ on: February 13, 2014, 06:26:57 AM
There is a HUGE price premium between 750 and 900 Watts.  I have been looking for a good deal for 3 years.

Huh?

I used to buy the PC Power and Cooling 910W Silencer supplies for $80 or less all the time in the past couple years.

Too bad they aren't around really anymore, solid supplies...

I was looking at the 1000W LEPA on Newegg just last week.  A couple months ago was buying 1300W Rosewills for $160 but with altcoins exploding large PSUs have indeed been rare the past few months...
127  Economy / Computer hardware / Re: (WTS) KNC Miner November Batch Jupiter 650 GH/s + on: February 12, 2014, 12:59:15 AM
ANTMINERS are 200GH for $1.45BTC.

600GH for 4.35BTC, or at MTGOX's current $575 price we are looking at $2500.

Meh, I'll up that to $2700.  Let me know.
128  Economy / Computer hardware / Re: 12 (2 T/hash) early Jan CoinTerra order. on: February 12, 2014, 12:51:20 AM
testerx's December unit arrived today ..

https://bitcointalk.org/index.php?topic=461077.0

He's not happy with the initial performance parameters though ..

Triff ..

Ouch so he's only getting 1.2TH at the pool...  

Lets do the ANTMINER Math again on this  -- 1.45BTC*6 = 8.7BTC cost for same hashing power in ANTS.  If we use the last MTGOX price of $575 that is basically $5K worth of ANTS to match a cointerra box... WOW - interesting.  I really wanted to bid on a goat box but it seems more and more likely by the time they arrive the only logical choice will just be to mine them out!

Now we all know today is a big lul in price due to all the exchange issues but still...
129  Economy / Exchanges / Re: MtGox withdrawal delays [Gathering] on: February 07, 2014, 02:45:57 AM
I found mine in there too! So how do we get out of the bad transx log and into the good one? Any thoughts?


You wait only 5-7 days if lucky and retry and hope you don't get suck for another 5-7 days...

Describe the first thing that comes to mind when I say this word:  MTGOX

If you answered "INEPT" you win a prize...

---------------

Hey I was a programmer once upon a time, I do not envy these guys at all.  This is a huge bug it seems that has just gotten much worse recently.  But still makes me wonder why they didn't take this seriously back in Oct/Nov when it happened back then...
130  Economy / Exchanges / Re: MtGox withdrawal delays [Gathering] on: February 06, 2014, 11:25:06 PM
Guess I will flamed for this and accused for all sort of bullshit, but I still recieve euro from mtgox, last one 04. februar. The one before that was 15 January so less then the 20 days even.

No we believe you.  Bank Xfers are a different issue than BTC Xfers though.

BTC SHOULD ALWAYS BE INSTANT - and confirmed within about an hour.

THE PROBLEM IS:

MTGOX will constantly "pretend" to send you the BTC, but never actually TX it to the network.  History shows if this happens to you it takes 5-7 days to actually get your BTC.  

The scare is this used to be a random thing that occurred every now and then (I had 2BTC stuck in NOV and chalked it up to a fluke).  But with 50-90% of all transfers being faked now (just a guess based on http://coinsight.org/mtgox.html ) this could be the end...
131  Economy / Exchanges / Re: MtGox withdrawal delays [Gathering] on: February 06, 2014, 08:51:49 PM
UGH I had been using Gox with no issues for small xfers.  Decided to pull  ~13BTC out and YEP - NO XFER!

WTF GOX!
132  Economy / Economics / Re: The Value of BTC, in terms of Hardware Purchased and Installed on: February 05, 2014, 06:09:36 PM
...the network speed will increase by another 100 fold by October (ref TheGenesisBlock)...

 ...conceivable that BTC will be worth $5 000 to $10 000 by the end of 2014.

Yeah because the Genesis block has been soo accurate before  Tongue  When moving up generations that have 100X more power (CPU>GPU or GPU>ASIC) the growth is insane for a bit but it HAS to slow down eventually as power isn't free  Wink  

Think about it this way.  I used to spend 4KW to generate 3GH back in the day with GPUs.  Today I spend 6KW to get 3TH (55nm).  The new 28nm chips are still 2KW for 1.6TH (cointerra) - we are beginning to hit that curve where the power draw improvements are starting to taper off...

I don't think we will hit 100 times faster than we are today this year - maybe next year  Wink

But yes $5K to 10K coins is believable.  Why?  Because its been growing by a factor of 10 every year.  $1, $10, $100, $1000 whats next?   The bigger question in my mind is the adoption curve, and where might we be on that?
133  Bitcoin / Hardware / Re: What ASIC to go with for 2.5k? (Or less) on: February 05, 2014, 09:10:01 AM
Dude this is a no brainer.

ANTMINERS are 1.45BTC.  

WAIT LETS SAY THAT AGAIN.

1.45BTC.  With $800 coins thats like $1200 including a $40 Corsair TX650 off eBay.  For 200GH (these OC to that easy all day long on any PS half-worthwhile).  Starts shipping in 2 days.

Grab two.  $2400.  400GH.  Only 800W draw means its like a little heater for the pair, no big deal.  

Just think about it this way:  a HASHFAST PREORDER cost what, $5600?  400GH for that too.  Sure it uses less power but IT COST TWICE AS MUCH!

---->  Preorders are dead.
134  Bitcoin / Hardware / Re: Antminer S1 - 4U Rack Conversion on: February 05, 2014, 09:00:23 AM
I had considered using one of these:

http://www.newegg.com/Product/Product.aspx?Item=N82E16811147164



I am pretty sure they would fit on their side in this case, and since its over 2' deep I think you could fit two ANTs and the power supply just fine.  Get a 1000W PS, leave the back slots open, etc.  The problem becomes:  can you remove that middle fan bar & drive cages easily, and does the ATX raised motherboard stand cause any issues?

I ended up buying the $54 shelving unit at Costco instead of trying to get the tin snips out  Tongue
135  Bitcoin / Group buys / Re: [GROUP BUY WORLDWIDE]BTMine v1 Miner 200GH/s BTC 2.4 on: February 05, 2014, 02:22:07 AM
If anyone is looking to buy more of these, I am selling mine (at a markup) over here.

GLWS they will all try to low ball..

eBay prices have dropped from $3K to $2K.  Forum prices have traditionally been half that.  With ANTMINERS being a much superior product and only $1200-ish, these Avalons with twice the power draw and high failure rate (even at stock speeds or less apparently) make these a LEMON  Sad
136  Bitcoin / Group buys / Re: [GROUP BUY WORLDWIDE]BTMine v1 Miner 200GH/s BTC 2.4 on: February 05, 2014, 01:42:47 AM
WELL this sucks.  I just got home to a dead unit that smells like it burnt itsself to a crisp!  Power supplies were CORSAIR TX750 units that run all my ANTMINERS.  Power draw was 900W last I tested (stock mhz).   I had not touched the config of the BTMINE unit (default software) besides setting the pool.  BOX WAS STILL RUNNING WITH NO FANS AND BURNT MY HAND TO THE TOUCH!  FIRE HAZARD!  Both power supplies power on and operate the tplink.

Box is cooling off now, took off the cover and will see what happened soon - modules too hot to touch still!   Sad

UPDATE - BOTH POWER SUPPLIES OPERATE JUST FINE when not connected to the BTMINE box.  Soon as I plug them in and turn it on with NO modules hooked up I get power for a couple seconds (fans spin up) then NOTHING.  Power supply protection circuit kicks in.  So looks like it has to be controller or power distribution board?  Still toying   Sad

For the record I've owned over a dozen Avalons and never had an issue.  This box yesterday for the first time dropped to 40GH for a bit (no reason) historically cgminer reported uptimes of about 3 days and about 2% HW errors... bummer!
137  Economy / Economics / Re: The Value of BTC, in terms of Hardware Purchased and Installed on: February 04, 2014, 11:25:08 PM
... No miners have ever lost money with Bitcoin, unless they converted to $US as soon as the BTC was minted.... but who does that?

WRONG.  Nearly ALL miners have lost money.  Many ASICs were BTC-only pre-orders only do you think the HASHFAST guys are psych'd that it cost them 50BTC per rig and they *may* recover 5BTC of that?  Even Avalon Batch3 was 100 BTC for rigs that returned 50 BTC.  Lets not even get started on BFL if you had paid in BTC 13 months before they delivered...

The only actual "profitable" BTC ASIC was Avalon Batch1, all other gains were due simply to the price increase.  

138  Economy / Speculation / Re: SEEMS LIKE LARGE BTC HOLDERS TRYING TO KEEP PRICE AROUND $800 on: February 04, 2014, 01:08:01 AM

The major BTC holders want to lower volatility, so more people trust, and buy bitcoin, which could make the price much higher than the $1,000 level


*bingo

$800 is the new $6 mark (post $27 crash) and new $100 mark (post $270 crash)...  We could be stuck here for 1-18months (remember it took from June 2011 - Feb 2013 to hit $27 then break $20 barrier again....)
139  Economy / Auctions / Re: KNC Jupiter 675 ghs (november batch) on: February 03, 2014, 11:23:59 PM
For the moment the highest bid is 9 btc.

Who?  How?  They need to post in this auction thread for it to be considered "valid" as far as auction guidelines go.

Considering ANTs are now 4.35BTC for 600GH this price is 2x "going rate" and around a newbie claiming phantom bidders paying double market rate does raise eyebrows...
140  Bitcoin / Hardware / Cointerra Security Breach on: February 03, 2014, 07:52:25 PM
http://cointerra.com/information-update-cointerra-com-security-breach/

DATELINE 2/3/2014

We are currently investigating a malicious attack on our website and email servers this weekend that has resulted in a security breach. We took our website down as soon as the intrusion was detected on Sunday afternoon and brought the site back up on Sunday evening.

The website has been restored to a secure backup made shortly before the breach occurred and all orders placed before January 31st 2014 are intact. Customers are again able to place orders both via BitPay and wire transfer as normal.

We immediately contacted the appropriate authorities and an investigation is already underway.

A small number of customers who paid for their order with Bitcoin between January 31st and February 2nd may have been affected and we are in the process of reaching out to those customers directly.

We will continue to investigate the full scope of the security breach. Although we do not yet have specific information regarding customer logins on the CoinTerra.com website being compromised, we can confirm that all passwords are encrypted (salted and hashed). However, as a precautionary measure we recommend that customers immediately change their account passwords.

Note that this will not affect the current shipping schedule of our units to customers this week.

Please contact itdesk@cointerra.com if you placed an order between January 31st and February 2nd or have received any suspicious emails regarding your order, such as:

Asking you to switch your order made with wire transfer to Bitcoin
Offering to move up your order to an earlier batch in exchange for quick payment via Bitcoin
Offering free shipping in exchange for quick payment via Bitcoin
Offering to sell “cancelled orders” from an earlier batch in exchange for quick payment via Bitcoin
Offering a percentage discount for quick payment via Bitcoin
We would like to make it very clear that CoinTerra has a strict policy of never offering new customers the option to buy into an earlier batch ahead of existing customers, or of offering discounts or free shipping in return for quick payment.

For all other customer support issues please contact support@cointerra.com as usual. Please understand that the allocation of resources to the security investigation may result in a delay in response times for customer support tickets. We will make every effort to resume our normal level of service and update the website with further information as soon as possible.

We thank you for your patience and understanding at this time.

Team CoinTerra
