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.

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.

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.

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.

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?

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.

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
you have to have the pc anyway.  so a perfect reason for having one with an i7 in it.

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).

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.

How are these miners controlled?

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

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.

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.

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

if it follows how all the other Avalon's work , one PI can control 6 or more, from what they are saying you may be able to chain a lot more to gather. tip there is a  internal controller so be very care full with updates you can brick one .

and it works on orange PI's now unless they dropped that , me and Avalon had a little falling out over gear i didn't buy direct they pretty much told go me f off unless i had bought it direct or pay very high price to replace some thing that should only cost 30 bucks and they give no support to non direct buys . so i stop keeping up on the Avalon 7 . and CGMMINER only works unless you are willing to send a miner to Luke the DEV of BFG hell make it work or convince Avalon to do it . Avalon did support BFG at one point not sure what happen .

Does anyone have a sense as to how much CPU the mining software and web interface takes on an RPi? I already have an RPi that's running the Stratehm proxy.

Just trying to explore whether I could run both the proxy and mining software on the same RPi performance wise.

Additionally, I guess I'd need to manually install their cgminer and web interface rather than just slap in an image. Hopefully the Stratehm proxy and Avalon web admin apps can coexist. I know that the proxy allows the port to be changed, so there's probably no issue there.

Yes, I know that I said the 721 is too expensive. But I'm weak and tempted, so I'm exploring the technical options Wink

Thanks Sidehack,

These look like they would sit nicely mounted to a rack shelf with a IBM 2880w PSU on top powering the three. really excited about these  Grin

i wasn't disagreeing with anyone just a statement of how it is and your right bitcoins are getting around and it would confuse others at first till  they get involved  there is so much more to this kind of currency yet to happen that will make bitcoins stronger and won't replace it any time soon . don't forget bitcoins started with CPU and GPU's.

Yeah, I wasn't talking about you but just in general.

Altcoins are pretty much for geek or traders Tongue

It's still the same for Bitcoin but with more overture.
