Is this a stand-alone miner, or does it need a Pi / PC with BFGMiner?
Doesn't it make more sense to buy an RX 470, mine 0.003 BTC per day with it. Pretty much equavalient to a 3TH/s miner but its efficency is 0.05W/GHS.
Keep that BTC like you normally would for "long term" while getting ROI in 3x as fast and having something that in 1 year will be resellable.

I agree
How do you put it with out others getting mad at you or taking offense. other then say it's like the GOV it's a bunch of old guys setting around making rules about the new world that no long work and they hate to admit it because there set there ways. or a game comes to mine wow refused to put some thing in there game because they believed it would make running bot software easier or hurt the game but after a year, after all the other games had done they put that feature in and saw how it improved the game. it'd called progress and some times it is confused with hurt and what hurt it can do.
I Don't mean that to offend any one.
The real problem is when someone think everything is black or white.
From that point, there is no need to argue. It's pointless.

Altcoin / GPU mining has been doing great that's a fact. Do I believe they will ever overpass Bitcoin in the future ? There is no way it'll happen. Bitcoin is starting to have an influence, to be know by everyone around the world. If I talk about Bitcoin to someone, a light might open but if I talk about altcoin, yeah they just don't understand it, do not want to know about it, they get confuse, etc.
So the reality is Bitcoin has a solid foundation, way more then any other altcoin.
So I agree GPU mining mining has been great by I also agree about sidehack argument. Altcoin is pretty much gamble. Bitcoin, is pretty much the gold of any currency around the world.

But you can't mine 0.003BTC per day with it. You mine something else and then exchange it for BTC. Good in that BTC gets used (the more its value is based on currency utility versus asset investment, the better) but in the end someone's paying an inflated price for a coin that stands a much better chance of being worthless in six months than just mining BTC. Some call it gambling, some call it theft.
How are these miners controlled?
Looks like they'll be run like Avalon4 and Avalon6 were, where multiple modules are chained together to a single RPi controller. The single-point failure part isn't so great, but since it's an off-the-shelf part replacement is super easy. Setup and configuration are also super easy because you don't have to track down IPs for every individual machine. Overall a pretty good setup.

Even with Bitmain's release of the latest S9 batches, I am severely thinking of buying some Avalons,

set a i7 -6700t on six threads it will do your mall work and mine for free at about 15-20mh
you have to have the pc anyway. so a perfect reason for having one with an i7 in it.
Is there a thread on how to get this going?
So why do people still buy Bitcoin ASICs when GPUs can reach ROI in 4 months. If the current ZEC profitability stays constant then its more like 2 months.
Are GPUs harder to manage for most people and too much of a headache so they buy ASICs?

Because Altcoins are like straw fire.
I studied this a lot there is a long list of reasons for and against alt coins vs btc.
I come down to we will always have a mix so a smart miner does all and needs to be very nimble and quick.
Translation : there is a place for ;
AVALON 721
ANTMINER S9
ANTMINER R4
Gpu rigs for alt coins
Cpu rigs for alt coins
Gpu+cpu rigs for alt coins.
You need to be able to understand what the rules of the game are to play it well.
Here is one example of a cpu rig like the lenovo M700 tiny
a mall kiosk needs a tiny pc which can be had for about 400-500
free power = yes it comes with the rent
set a i7 -6700t on six threads it will do your mall work and mine for free at about 15-20mh

To follow up on Phil and sidehack and yxt they are all correct. Some alt coins are terrible garbage design for theft by deception. Others have some weight behind them.
They actually serve a purpose to aid and help BTC and that is Liquidity which is lacking in BTC due to a transaction cap of 680,000 per day which is never done since to do that every block would need to be empty.
BTC only does 240,000 to 300,000 transaction a day. Alt coins fix this (well help to fix it).

Most altcoins exist for people who only care about short-term profits. People caring only about short-term profits were the principal cause behind pretty much every depression, recession and financial crisis in history. Knowing this, some of us would rather be in it for the long game. Sure there are a few coins actually built for long-term viability, but that's only realized after they've survived being abused by the flock of pump-and-dump circlejerkers.

I've had at least 20 Avalon6 come through hosting (most are still here), with two bad boards total. In about half as much time I've had around 25 S9 come through hosting with 4 bad boards total. I'm honestly surprised it's not higher than that. They do cost more, but there's something to be said about reliability (and, you know, customer service when something does go wrong).
Not sure you can directly compare those 2.
20 Avalon6= 40 boards
25 S9s = 75 boards
Avalon6 board failure rate: 5%
S9 board failure rate: 5.3%
Failure rate per miner is higher on S9 though.
It's also in less than half the time, and during a lot cooler period overall so it should have been easier on the works.
And assuming a 5% difficulty change, free power, a 1% pool fee it would take over 400 days to break even.
Also assumes your miner is worth 0 after, which is never true. If its worth $300 still after 200 days, its break even is 200 days. If you can value it higher, you can break even soon.
Good point.
The s9 still goes for 1500. It came out in June which is more then 120 days.
My fail rate on Avalon 6 was 1 of 16 boards.
My fail rate on the s9 was 4 of. 18 boards.
To be fair the Avalon 6 ran in the solar array in much cooler weather then the s9.
At the moment I have 7 s9 boards running.
I plan to buy at least 3 avalons but I could do 10.

expensive, but it is good that Bitmain has competition.
yeah I down with this. note 8 pcie jacks into 900 watts = 112.5 watts a jack.
months ago when they were designing this gear they asked for community suggestions .
I asked for more jacks to end cable meltdowns. They listened and followed my suggestion for this alone I will get some .
Are they cheap no they are not. But cheap would only start a price war.
I rather this price but maybe a little better watts per gh.
I can run 3 with ease on my dual dps 2000 4k boards.
I think my first order will be for 2.
If there is a Moq of 10 I will do a group buy like I did last year.

I'd be happier with them if they were a match per TH vs the S9 rather than targeting the R4 as their price match.
The "smaller" power footprint though is a good thing, and will help them sell quite a few miners.
Bitmain is only selling the R1 and the S7-LN
5% difficulty is a bit on the high side at this point I'd say, unless Bitmain drastically drops the price on the S9/R4 or gets someone that WILL compete with them on pricing (Avalon has never bothered, but they do tend to provide higher quality gear).
Interesting but I don't really see this being profitable, $888 for 6 Th/S isn't really all that good and for everyone with electric over .09 cents/KW this thing isn't profitable enough to even break even on the miner, then factor in rising difficulty and its really a total loss for most people. It's not like you can really resell this for much after, look at the S5 its selling for like $40 now.
I ran some numbers using this calculator:

And assuming a 5% difficulty change, free power, a 1% pool fee it would take over 400 days to break even.
Since I am starting from zero, this doesn't work for me.
Yeah sadly it's hard to justify looking at the numbers even with zero power costs. The past two difficulty changes have been great though.

Edited to add:

Running a different set of numbers: 2.5% difficulty change, $0.12/kW power, 1% pool fee
That would require a BTC price of $1125 to breakeven in 500 days. Still not good for me.
