ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[philipma1957]

Coins dropped to 274 overnight. So do we get a further price drop ?  Not yet still 416  shipped to NJ,USA

Only thing that is good new is Diff dropping about-2%

[sidehack]

I should have seen that price drop coming and warned everyone. Whenever we take in large orders or invoices paid in coin, the exchange rate always plummets immediately after. Every single time. It's a curse. So yesterday we took in something like 15BTC on one invoice, of course it drops overnight.

So looking back at all the Bitmain releases in the past. It seems if you have free or cheap electricity the only miner that would of got ROI and made you some profit is the Antminer S1.

The S2 / S3 would of been getting barely ROI right at the moment.

The S4 / S5 not even close.


This is assuming one pays retail.

PSA - this is also assuming that they send you working miners to begin with. Please see my thread:

TL;DR Bitmain mailed me two broken miners in January. I sent them in for repairs 3 times, which took over a month. I lost out on ROI, asked for compensation, was send 20 mBTC, some stickers and a t-shirt.

How many BTC were you able to mine with the stickers and t-shirt ?

Looks like everyone is happy with Bitmain right now.

Can you guys have a look at the firmware on The S5 looks like extremely high reject rates. The S4 firmware seems to have fixed the S4's problem. But the S5 seems to be doing the same thing on westhash and ban.I have tried all sorts of settings and configurations same results. Thanks in advance

I think they expected him to resell them and make up some of his lost ROI.

Everybody knows SHA256 is t-shirt and sticker resistant.

Can you post a screenshot of S5 side and pool side of what it looks like?

Darn, was about to put the hammer down on an S5, waited while a Bitcoin-QT picked up 12 hours, did a bit of work, went to buy and BAM, the new low btc value drove up the btc cost.

Also, Bitmain does not endorse any third party solutions, however, CryptoGlance is a nice status reporting system Yoshi even uses time to time as well as M's Miner.  (Both solution works for any CGMINER API enabled Bitcoin Miners.

Cheers Bitmain! Thanks for making the Antminer so easy to work with.

Here goes the endorsement
I use cryptoglance - Works with a lot of pools and miners looks good (computer free and cell app-Cell app cost 99C thru the store well worth it) - It is fully supported by user cryptoglance. You have a problem you wont have one for long if you let them know.

dont know how you did your math, but my 2 s3s that i paid 1.36 btc for have nearly made 4btc. sounds like a profit to me.

on top of that, those s3s have a few months left on them.. probably another 1.5btc.
they also funded the purchase of s5.. free of charge to me.

Interesting.  I went to buy an S5.  Delayed a bit and had to try again.  Price went up in terms of Bitcoins as the value was dropping.  So, I quickly sent the increased BTC amount from Coinbase and it shows completed.  But, on the Bitmain website the purchase shows expired!

The order shows created at 2015-03-18 17:55:10.0 on Bitmain.  Coinbase shows completed at March 18, 2015 13:57 EDT.

I believe I made the purchase within a couple of minutes of observing the increased price.  

And I've already bought the power supplies.

Anyone had any experience getting a btc refund from Bitmain?  These aren't shipping until March 30 and I expect Bitcoin to take a spring rise - on the other hand buying now and knowing the sale when thru would allow timely preparation.

Some ASIC manufactures have customized the default cgminer API. Makes it really difficult to manage a code base with exceptions everywhere to handle those API changes.

That seems unlikely. Even if you ran them at 500GH/s@400W and started mining with 1TH/s on August 1st, with no pool fees and 100% luck you'd only be at 3.34BTC returned. If you don't pay for power you've made a decent bit of coin, but if you actually have to pay an average rate for the 4400kWh you'd use that would eat up a whole lot of that profit. I'm sure you've still hit breakeven unless you're paying >$0.20/kWh and are now in the profit, but for most people it's still pretty marginal.

There's a time and place for everything. I feel as a representative of a business you should not be using them. I own a small online store.

I own a small business too.  I infrequently use emoticons in my business emails.  I hate the written word because it's difficult to tell the intent and emotion of the writer.  I don't feel that emoticons should be a taboo for business emails.  They should be used sparingly.  I must have the right balance, having just celebrated 15 years in business.  I never had a client complain, yet.

Having said that, I think sidehack already said it perfectly:

But when your entire reply to a valid question a paying customer has about the machines he purchased is a series of emoticons, there's room to complain. It's basically dismissing the question offhand (and in a manner which could be seen as condescending), which is rude.

Bitmain reps here, do need help in the appropriate use of emoticons.

Exactly the attitude that makes BTC appear supremely suspect as a medium of commerce.  The recipient clearly has no responsibility to provide equitable value!

Whether the exchange is in Bitcoin or something else, whether transacted online or on mainstreet, it's all the same - you can get scammed or have a bad experience.  more than once I've recieved a less than proper amount of cash back at a mainstreet (KFC) business. It's a matter of knowing the rules of the transaction - the means of value exchange (BTC, USD, IQD, Euro, etc) has nothing to do with the transaction.  Have a problem with rules? Then that's a different discussion.

Guess I was wrong Dogie, you are purely a lackey of Bitmain!

You barked up the tree with Dogie on this one.  I'm grateful for his, and everyone's good help here.  I'll also speak up with him or others when they are wrong.

A bunch of grown men (hopefully) talking about the use of emoticons. Please, can we just stop this and get back on track. I'm not saying this of offend anyone, but if you want to talk about emoticons I'm sure there is a whole forum somewhere dedicated to them.

[opentoe]

I tried Cryptoglance and it looks pretty nice. Although since the graphics are so large you can't get that much on the screen at once. If you had a few rigs, then it would fit. But if you had over 10-15, where would they all fit....besides just scrolling up and down all the time.

Also, how many temp sensors does the S5 have? Crypto indicates there are three (3) temperatures, and they all are different.

And what is your reject rate? I read someone had high reject rates. What would be the normal range or percentage of rejects?
