Topic: ROI question on mining rigs (Read 7817 times)

I bought a card for 300 dollar in 2016. I just sold it for 500 dollar just now. The mining is quite profitable.

for mining;  the only thing you can factor in is the payback/ROI total vs. the value of the gear if liquidated for sale.  This is true scaling roi in my eyes.

but I don't count on getting things by a time.  I am just excitedwhenever anything is coming in.  Especially is it has paid itself physically off, and/or its profitability margin takes theoretical ROI sooner then the 6-3 month mark.

Buying and holding is different thing. Mining is one-time buying, and some income depends on much factors till ROI. In case of ROI is not a question that trading is better. If you trade, you can flush your depo. If you mine you can't "DeMine" your rigs except high electricity cost. It's not better or worse. It is different.

That is why I keep on mining all the time and add rigs when I have spare money.

People keep saying that you should be better off not buying till its rising;

But mining crypto is similar to purchasing crypto in many respects such as:

If you buy the equipment after the rise;  you do not profit from the rise.  This is key.   So; get used to mining during down times, to fully and actually benefit from the up times.
If you focus on solely one coin/algo, it can be rewarding, but mining only one coin can be a trap.
Long term algo stability (Pick an algo/plan and stick to it unless a better plan/algo develops right in front of you and will remain consistent) will almost always produce more in the long run then short term goals for quick profit.

If you are mining for a business; and pay a premium for power;  your business model is flat-out flawed.

Mining is about future profit; not about short term profit.  If you want short term, go to a casino or the exchanges.

You can still find GPU's for good prices, you just have to work on their time;  not your desire to be ASAP with acquiring them (which everyone seems impatient more and more as I get older).

Every person has dfferent meaning of profitable. so it all boils down to what do you want to achieve, if your a day to day profit then price right now is kinda low roi may take a while but if your in for a long term then just hodl and dont mind the price dip.

If the price of the altcoins are similar to now in the next few months, it is only profitable to mine for the cheap electricity people.

At the current prices its going to take a while to ROI and might be better off buying crypto and holding. If you bought your rig 6 months ago before the spike in GPU prices then its a different story.

The fastest for mining the ZEC is the nVidia 1080Ti.

what is the faster GPU for mining? i want to build mining rig
i've been try with AMD A6 profit mining just 0.000011 BTC per day

That is a ton of awesome infomation, thank you so much for all the detail it's greatly appreciated and definitely helps me understand all the wonderful stuff much better!

Asrock 970X Extreme 4 on socket AM3+
Asrock FM2A88X Extreme 6+ on socket FM2+ on my usual "mixed rigs with an APU"

 There are a LOT of similar options for Intel, and several others for AMD, but this pair tend to be the lowest cost or VERY close to it, and they *work*.

 4, you're looking at a very limited selection of Intel boards - the one that sticks in my mind is a Biostar "Racer" model with 4 x PCI-E 3.0 16x slots (but not all of them are electrically 16x, which isn't a significant issue for mining on).

 The MSI MB you linked to WILL support 4 dual cards - you just need to run it as an open rig, or use a case like the Thermaltake Vista V34 that has specific "8 peripheral slots" support.
 Cards do NOT have to overlap the motherboard if the case makes provision for that (most cases don't).

 Just don't try to run more than 1 of the Gigabyte AORUS cards on a setup like that, they won't physically fit (those cards are at least 2.5 slots wide and some apparently are 3).

 The MAJOR down side on 4 card rigs is cooling gets a lot tougher to make work. I doubt you will be able to keep a 4-card non-riser rig full of 1080 ti cards cool - it's hard enough by report to keep 4 card rigs like that with RX 470 or 480 cards cool unless you undervolt a lot and turn the TDP limit down, and those are only 150 watt OR LESS cards to start with.

 I end up using one of the Gigabyte "ITX" very short cards in slot 3 of my *3* card rigs in order to keep the middle card cool (the middle card gets ONE fan completely unobstructed and the other fan(s) almost completely blocked, vs the #1 card having all fans with a narrow space for airflow and therefore partly obstructed), running 3 x 1070s.


 Mining is NOT bandwidth-intensive to any significant degree, or riser rigs with cards running from 1x slots would show VERY bad performance on those cards.

Which boards are you using that can handle 3 dual PCIE cards? I would love to know - I'm using all no riser builds but my builds are all 2 GPU, would love to get some 3 or even 4 no Riser rigs setup!

Thanks, and if you know of any boards that support 4 that would be awesome as well. I've seen this one but not sure if it will fit 4 1080Ti's -

https://www.msi.com/Motherboard/Z270-XPOWER-GAMING-TITANIUM.html#productFeature-section

It looks like the 4th one on the bottom wouldn't be able to accommodate a 4th dual GPU

Can you elaborate on which PCIE specs are viable for mining and which ones are not viable / when x would become not viable anymore?

Or go my route and build 3-card rigs with no risers and still have the spacing for good cooling - and they're not much IF ANY MORE per GPU than riser rigs while being noticeably easier to set up, get working, and tend to be more reliable.

 Mining generally does NOT need PCI-E 3.0 for full speed performance, as it's not bandwidth-heavy to the GPU in most cases - so going a lower-cost AMD route on the AM3/AM3+ socket and DDR3 (which is STILL cheaper at the low end than Intel's needed DDR4, though the price gap IS finally narrowing) is very viable.

My earnings on zpool speak for themselves via the previous links for my 1PHSD address, or even the 1K address you quoted (ignore the gigantic spike in my last 24hr payout; it was a donation)....  The error you speak of is directly related to the spread between coins buys/sells on the marketplace and volatility therein.   Notice how most coins swing by ~20%

I see my payout pending line fluctuate with the vary coins I hold on exchanges and am mining (AUR, DGB, etcetera)... so I have found where it comes from myself.  I challenge you to do the same and see the exact correlation.  Just because before the coin sold it was valued at something, doesn't mean people are paying that for said coin;  buy orders are typically under, and not always 1 satoshi under.

To the 2nd reply above,

I use windows;  Just download the latest driver, and used the alexis78 version.   Easy as pie for the layman to set up; and using the nemosminer package you can download the latest miner apps in one shot.  You can use his batch file, or one of mine.. they all have different uses and work differently depending on what one you use for which feature you like best.

don't use zpool use yiimp, zpool earnign are 30% less than what is reported in their website, it's indeed a scam, use ccminer 2.0 to mine skein with -a skein parameters, or use the alexis version which is even better more speed

Alright.  Just broke down and ordered five 1080 ti cards to mine zcash.  Now trying to figure out Linux/Windows.  If Linux, which distro? Does Claymore's program support the 1080 ti cards in Linux?

always glad to lend a hand... its what i'm most proficient at in life I think....

If worst case comes around; follow phil's route and find MB's that have 4x PCIE slots (any combination of 1x-16x) and just hook up 4 cards cause I doubt there will be any issue at all with lane addressing;  or any older 4 by 16x slot motherboard like the 1st gen i7 boards so you don't need risers at all  (as long as they aren't bigger than 2 slot like the evga non-ref cards are)... cause they are relatively inexpensive as a MB/ram/CPU combo second hand.   Many of my miners are on this platform.

Thanks again I definitely will have have a few, I've basically been reading non stop for the past week - the problem with this the more reading I'm doing, the more money I'm spending on GPU's lol. I just pulled the trigger on 3 more 1080 ti's for a 3 card non riser rig, just trying to figure out which mobo will be able to do this at the best price.

Ok now that I've spent money, back to more reading.

And again, thanks for your help and time, much love!

Once you get your feet wet you realize its actually somewhat simple.

The hard part is testing everything over and over and over again....  Its taxing....  This is why I support minerx in what hes doing here with his version of my batch;  it surely lightens the load  He goes that step further and provides a whole package.

I'm an ass and make people do their own work... lol

If you haven't yet, reading through my posts via the batch file link in my signature;  you could learn a lot of the juicy stuff.  Things like the normalization, the original batch file, etc... they all do (hopefully) a good job at describing what's what and how it works and will bring more scope to what you must pay attention to.

thanks a ton! i have so much to learn it's staggering

mineskein.bat

This should get you going.

replace my BTC address with your BTC address; and either delete " **INSERT ID HERE**, " or change it to " SOMETHINGELSE, "

How are you mining skein?

I am trying using nemos zpool but it's mining everything but skein atm so I don't know how to get it to just mine skein, it keeps rejecting if i delete all algos except skein.

I only have 2 1070's on a windows 10

I'm lucky... I get deals on computer parts since I live in Silicon Valley....

memory is dirt to me and my friend (he used to be a head at PIIceon back in the day)...

The last H97 Anniversary We ordered for Henry's rackminer only cost $130 shipped... came with ram and processor too.

That price is bonkers if you ask me...

Let me try and break down the price of Henry's Rackminer:

$130 MB+CPU+RAM (ebay score BIN)
$100 Rosewill 4U case (he got a deal on Amazon for damaged box/returned or something retarded)
$100 Coolmax 1600w PSU (his friend sells them)
$80  6x risers (right angle, and 6 pin connector)
$2000 ($400/ea)5x GTX 1080 (used, craigslist)
$600 2x GTX 1070 (Used, CL again)
$25  Ace hardware, aluminum trim for making bracketry to support the GPU
$45 130CFM fans x3
....   I dont think I missed anything else....

That's $3080..... and it does this:
http://zpool.ca/?address=1kLsGT9egk3utSKZH46ydTbKj5oMnmBoN

Presently he has added a second 1070, so he had me put both his 1070's in his home pc so he could game on them as well... that's why you see two miners....   subtract .5Gh if you don't want to count one of the 1070's.  still quite a profit...

 That's if you insist on going to 6-card riser rigs.

 For $6750 you can easily build 5 and possibly 6 no-riser 3-card rigs, and if you go with Phillipma's favorite Biostar 4-card board you can probably build 4 or 5 4-card rigs.
 
 The smaller rigs have the advantage that if something breaks, you lose half as much hashrate - at the cost of slightly more power consumption and *usually* somewhat more space needed.
 
 You also get better reliability IME, risers have a bad habit of having issues and 6-card rigs can be a pain to get working reliably since the drivers aren't really INTENDED to handle that many cards.
 
 You also don't NEED a "frame" for a non-riser rig, which saves back some of the money (as does not needing risers) you have to pay for 2 MB/CPU/RAM/drive sets (PS is a push, one big with a GAZILLION connectors to power the GPUs AND the risers vs 2 half-size "normal number of connectors needed" is pretty much the same price on high quality PS).

 
I'm NOT impressed with a couple of the blockoperations picks:

 Not real fond of Antec PS, and their plat PS is *BARELY* more efficient than the EVGA 1300 G2 "gold" or the Seasonic X-1250 "gold" models while costing noticeably more.
 
 They're paying too much for their ram - 4GB is plenty for most mining rigs, and DDR4 still carries a price penalty over DDR3 (but if you INSIST on Intel, most of their recent MB are DDR4).
 I'd suggest 2GB but it's almost impossible to find 1GB SIMMS any more (and they've gotten kinda expen$ive).
 
 Buying the OS on a stick/SSD might make it easier to deploy the rig, but does waste a bit of money over just buying the stick and doing an install of a FREE OS (even the free mining-specific OS distributions).

 
 With all that said though, that site DOES give a good "this is a place to start" on the cost and choices to make for a 6-card riser rig, and their total cost is pretty reasonable all factors considered.


 As far as electric cost goes - before I moved into my current place (fixed-price electric built into the rent by negotiation with the landlord before I moved), my last full-month electric bill was for $394.86 all up, on 8640 KWH used, or just a bit under 4.6 c/kwh

 I figure about 13k of that was mining gear.



 Buying hashrate from Nicehash *can*, sometimes, make more than owning - but most of the time you're fighting other folks that probably don't HAVE any mining gear and you end up paying more than you would make from pointing YOUR gear at Nicehash, much less what you can often make by pointing it at even MORE profitable options.

I wasn't very descriptive with the item names (should probably do that), but I made running totals of how much I spent across newegg / ebay, etc. Most was from Newegg lol https://pastebin.com/KxanE0g8

Man that is good! I pay over double that ($0.20/kWh) congrats man those are good earnings indeed for only 10k investment!

$0.075/kWh, used a little under 5000kWh last month

How many kW are you running and what are you paying per kWh?  Have you seen your electric bill yet?

I invested a little under $10k in hardware, this includes electrical upgrades and also cooling units

https://i.imgur.com/MRqCW8B.png

buying hash from nicehash make sense only if you know or you expect that the coin you are mining is going to increase a lot, otherwise you are wasting time and not making any profit, it's very similar to trading you buy because you will sell higher, but if you mine with your hashpower you don't need to wait you dump and take your profit

I am a firm believer of renting is more expensive than owning.

Less to invest, but waaaay more to risk in investment to rent.

has anyone done any comparison between mining rigs vs. buying hashing from somewhere like nicehash?  If there isn't too much of a price difference, might remove some of the risk of owning mining equipment and/or the ability to purchase various hashing algorithms.

 The total hashrate in ETH equates out to appx. 1 million AMD GPUs - which isn't even in the BALLPARK of their total sales on the RX 470 and RX 480.

 If you add in ALL of the hashrate on everything else, it MIGHT double that figure.

 Then factor in a LOT of older AMD gpus are mining ZEC, some are still mining ETH, a few mining other stuff, then subtract out the NVidia brigades....



 AMD cards are not in short supply due to mining (though it is a small factor, there was NO shortage on the RX 4xx series for many moons up to last month when they were discontinued), they are in short supply 'cause the RX5xx lines haven't gotten up to full speed yet *AND* AMD is selling MAINSTREAM cards that perform comparably to many of the high-end cards of the last generation for well under half the cost while eating half the power *AND* Nvidia has been very slow to move DOWN to the mainstream segment on their current generation cards.

 I also suspect AMD has been a bit slow DELIBERATELY on getting volume production and shipping going on the RX 5xx series so the remaining RX 4xx cards could get cleared out, since they don't have a lot of competition YET in that segment.


 I highly recommend AGAINST Poloniex - I had nothing but ISSUES far too much of the time I dealt with them over the last month and a half or so. They seem to be suffering some SERIOUS "can't handle their growth" pains.

 I don't like how Bittrex has their website set up in some ways (their pop-up "order confirmed" RIGHT on top of the main menu is VERY irritating, as is their insistance on using Crapcha) but they do get the job done and don't lag to hell and gone for hours a day like Poloniex does most days - and they don't hang on to your withdrawals for DAYS at a time.

 Never used Kraken, GDAX, or Bitfinex - but I am probably going to be checking one of more of those out in a month or so (I have a move tentatively set up next month into a MUCH better place).

 For getting your fiat into / out of BTC/ETH/LTC I find Coinbase works reliably, though their ATH transfer times are a bit slow that seems to be true for everyone that uses ATH.

 Poloniex and Bittrex have NO option to deal in fiat at all.



 See my last post for *MY* estimate of when the current very nice profitability will come to a screeching halt.


 IMO LINUX is the way to go for mining, though it would be nice if it had better tools like Afterburner for tweeking cards with.


 Open air rigs are usually a hair noisier, but you don't need MASSIVE fan volume on them like a "in a box" rig does to stay cool so sometimes they're quieter - and they're almost ALWAYS cooler.

 They are also a little less expensive (no case cost), and they use a little less power (no case fans needed, or you can get by with a MUCH LOWER POWER fan at most).

Sounds like starting out with 3x 1080 ti nvidia cards is better than starting out with with a different brands/model GPU x 6,  and I have the capability to add 3 more cards in the future as I pay off the current set up.


I assume things like the Operating system (Windows 10 versus Linux), and what memory, SSD brand, etc don't matter too much... 

But for the MOTHERBOARD and PDU,  can anyone make any recommendations? I need a motherboard that can eventually support 6 x GPU, and a PDU that will be able to handle 6 as well.


Also, how noisy is an open-air system versus closed air?  Is it as loud as for example, when you turn in a 2U server or loud commercial router? What options if you want something as quiet as possible?


What is the advantage of an open air that so many people go this route?  Does it cool better?


Thanks

yeah  no one knows how long it will last.

but I am netting 80 dollars a day using 2kwatts of power.

mining with:

 9 x 1080 ti nvidia cards. 
 3 x 1070 nvidia cards.

my mother boards,psus,cases etc were paid off last year.

and the cards above will be paid off in a little bit.

a 3 card nvidia can be built for

mobo = 80
cpu   = 90
ssd/os = 50
psu    =  110
ram =     30
riser = 10

370

3 1080 ti as low as 1930

2300 all new open air rig.

it will net 30 a day

will it do it for 77 days  I don't know

for faster ROI, i recomended buy some vga at second condition, so we get it cheaper than buy new vga, i  have 14vga buy at 2nd

Any of those would be a good choice. There is aslo Cryptopia that is good for new coins and it's been around a while.

https://www.cryptopia.co.nz

There have been many exchanges that have come and gone since I began in Crypto in 2014. The few I lost coins on were from not paying attention to the warning signs that were there.

https://bravenewcoin.com/news/36-bitcoin-exchanges-that-are-no-longer-with-us/

What exchanges do you recommend?  These are the top top 5 (in no particular order) that I came up with...Since I'm in the U.S., prefer U.S. based exchanges.

Poloniex
kraken
bitfinex
GDAX
Bittrex

With a 100% ROI of 2-3 months on average, ATM GPU mining is a no lose proposition as long as you don't mind dealing with the noise and heat. Trading is a good option for those with limited funds or space to setup a mining operation. The risk of trading/holding is large price fluctuations and the coins you buy could go down and you may be stuck holding the bag. With mining you always have the hardware that can be resold.

Bad exchanges are also a risk, but it can be minimized by sticking with reputable exhanges that have been around a while and only keeping what you can afford to lose in your account at one time. Overall I have made more profit by trading and holding than mining by far. The hard part is knowing what to buy.

So if this is the case, what would you recommend as far as ASIC vs. GPU vs. buy/hold vs. trading?

ASICs - special purpose so old equipment can't be re-purposed - almost no resale value.
GPU - cards and MB can be resold without taking too much of a hit.
buy/hold - simple, but one is hoping the currency goes up.
trading - 90% of traders lose money.  Exchanges have a history of being hacked. 

Which program are you using for multi-algo switching?
Is that the one in the screenshot?

A 3-card RX 480 / RX 580 rig RIGHT NOW will gross over $300/month on ETH, somewhat less on ZEC - then subtract the electric cost (probably $1/day or a little less unless your electric is NOT low cost).

 Cost to build such a rig with reasonable care at parts buying is $1200 or less, you MIGHT get it down a bit under $1100 or so with very careful selection of the lowest-price parts.


 This was NOT the case as little as 2 months ago - profitability on ALL major coins has more than doubled over the last couple months as many of the major coins have had HUGE price runups (and the difficulty has NOT been able to keep pace).
 For perspective, my mix of ASIC and GPU gear hasn't changed much in the last 3 months (I added *one* GTX 1080 card), but my income has jumped by a factor of *ALMOST 3* over the last 2 months.
 (I can't wait 'till I get into the new place I have lined up with over double the power available - I'm power-limited at this point BADLY).


 The nice thing about having quite a few profitable coins is that if one coin has a big jump, it will soak some of the hashrate out of the other coins in the "basket of profitable coins" and drive THEIR profitability up some as well, 'till the profitability is back in the same ballpark for the "basket" coins, so you don't really HAVE to go chasing "the most profitable coin" every day or every hour to benefit from the price jump of one specific coin.

 There is also the Nicehash option - they're usually pretty competative on profitability with whatever the "hot coin of the day" is.


 One other major issue to keep in mind.

 ETH is going Proof of Stake at some point, *probably* this year sometime - at which point there are over 29 THOUSAND TERRAHASH (this amounts to about 1 MILLION GPUs) worth of GPUs plus whatever gets added between now and then that are going to be looking for new homes, which is going to HAMMER profitability on every other coin that CAN be mined by GPUs (mostly the higher-profit by AMD mineable ones, as most ETH is probably being mined by AMD cards) - at which profitability for GPU mining is probably going to drop back down to the ballpark it was in 2 months ago even if the current coin PRICING stays high.

See my link on page one for the 1k address.

He spent about 3k I think.  Actually less than 3k...  the two month full speed running total still hasn't hit for the hashrate the machines have.  It's still increasing.  Compare payout history for past weeks to see how well it did.

re: hash rates.

Checkout this link for some from various cards.  Would be a good estimate.

Thanks the https://blockoperations.com/6-gpu-mining-rig-amd-rx580-intel-lga-1151-ethereum-zcash system looks interesting.

How does one calculate in advance the approx hash rate I'd get on that setup?

Also maybe this is a dumb question but I assume this is good for mining any GPU based coin right? (Not just etherium and zcash)

Where are you coming up with those numbers?  This guy, blockoperations, is a pretty big miner operator and on his website he has some costs on building a rig - 6 GPU for 2,250.  He includes a break down of the components and prices.  So, for 6k that would only put you at 2.6 rigs.  Maybe it can be done cheaper than blockoperations, but at the same time quality components don't break down as fast.


https://blockoperations.com/6-gpu-mining-rig-amd-rx580-intel-lga-1151-ethereum-zcash

OP after a quick(and pretty rough) calculation I think for about $4000-6000 you can make yourself 3-4 rigs which will net you about $400-$500 in total every month. Now if you could work something out to pay less for power you'd be swimming in money. These new electricity meters are often checked wirelessly and can also have their settings changed this way, without need of opening it up and breaking the seal or whatever. Just a thought

Its all shown on the wallet page.   skein primarily mined using ccminerAlexis78.


I don't follow the heard;  I do my own research and It lead me here....   before that, I was on Lyra2V2, but its profitability took a dive, and was not near as consistent as skein.

I havent tested timetravel myself yet.  Kinda been very happy with what works, on top of the fact that coins like DGB and AUR are jumping in the markets.... so why leave the profitable algo??? lol

Are there any writeups for setting up a 1080ti rig?

 

You lucky guy! In germany it´s 0,32$ ... I am still mining but I don´t earn a lot.

If you mean Bitcore then I get ~26.5 MH/s per card

the 1080ti is very good at skein almost double of one 1070 but don't consume double the wattage, so very efficient, what are the speed for bitcoin core, the new coin with timetravel10?

It really all depends on the price of the alt coins staying strong

This is just 2 x 1080ti's, and is constantly fluctuating with coin prices and profiability etc.

What miner are you using to get that that's pretty impressive

That is right for the used cards and if the price of coins drop, ROI will be much longer.

What hashrate are your individual 1080's getting?
Which miner are you using?

cheers,
Ed

Keep in mind the reason every AMD video card is sold out right now is because EVERYONE is building rigs.
Therefore the difficulty is going up and the profits are going to be going down as all the new rigs come online.
Over a 25% increase in the past month.

Be sure to include this in your calculations.

If ETH goes back to the price it was 2 months ago - you'll be able to buy lots of mining rigs cheap - because they won't be able to make money

...AND

Ethereum is going to switch to POS (no more mining) which is going to have a huge impact on every coin as all that mining power needs to find something else to mine.

Re: using mining rigs also as computer workstations

If one were to test this idea out, is there anyone selling a pre-built for dual use purposes (mining/office work), or would one have to build it themselves?  Building a rig wouldn't too hard, but having rig that has already been tested, has quality components, and a company behind it would be better.

Some quick googling, looks like there are docker GPU miner containers out there.

So how about the 8 GPU pandas (if one can get a hold of any)?  If you don't want to build rigs yourself and try to standardize on equipment so it is easier to diagnose when things break, are there any decent priced pre-built rigs out there and how do they compare with the pandas?

Re: using mining rigs also as computer workstations - this is a very interesting idea.  I assume you are using Windows and then just have the mining software to auto-start in the background.  How reliable has this been?  Thought about using Windows as the underlying OS and VMWare workstation (or something similar) to run a specific mining distro (that could hopefully see your GPUs) in a minimized window (or possibly hidden in the background - donno if this can be done) which might give a bit more functionality and/or monitoring capability?  Or maybe use a Docker container if there is one built for GPU mining?  Might take a bit more resources (RAM/CPU).

Any issues with people complaining about the noise of the GPUs or as long as they are underneath the desk the noise is bearable and people get used to it?  What about the heat?  In the winter the workstation could be used as a person's own personal space heater.

I'm thinking something like offering a free computers to a small business as long as they pay for the electricity and keep the computer on 24x7 and connected to the Internet.  Wish I owned a small business so I could do something like this to my employees workstations.

Always interested in the multi-use ability of using miners for various purposes other than mining.  ie. waste heat used to help with the distillation process of making liquor.
https://news.bitcoin.com/south-florida-distillers-bitcoin/

I work at a college and my co-workers are constantly replacing Dell computers.  Don't know if the college would go for building mining rigs that could also be used as a workstation, although the dual use and the ability for the mining on the workstation to pay for the cost of the workstation (and maybe even generate a profit) over the life of the computer is interesting.  If Dell came out with a dual use workstation - mining and general office use, that would be interesting.  Use the first year for mining to pay off the equipment cost and the following years for profit and/or saving for GPU upgrades and/or eventual workstation replacement cost....Although, we have been shifting away from desktops towards laptops.  Not sure what the ratio of desktops/laptops is, but probably at least 50:50.

thoughts?

I beg to differ on nvidia.


Mining an older algo;  with 5x 1080 and 1x 1070;  over 1K/mo in earnings.  thats not chump change in comparison..  better wattage/hash ratio too.

my equivalent of 3x 1070, earns me over 300/mo presently.

see for yourself:
http://zpool.ca/?address=1PHSDYvVp6HpqtuUPocK41DrdeHbbezaeP

now the profit is less than before, 1 months ago after the boom of cryptocoin, now the diff of every coin is 2x higher, the profit per rig is $500 month, which is still very good, you can roi in 6 months with a rig of 6 x 1070

With current market price for ETH, a 6 rig investment will yield you a net profit of $655 per 30 day period, when every gpu is able to push out 30mhash/900mhash dual mining. Your investment for said rig will be anywhere between $1800-2300 depending on where you buy your parts.

pre-built rigs are great if you want to pay $100-500 extra to save yourself a few hours of price comparison/assembling. Nvidia doesn't even come close to AMD when it comes to mining ETH/DCR.

In my experience the investment has been very good... I built my first 12 dual GPU rigs in 2013-2014.

In 2015 I sold off almost all of the GPUs and quit mining -- mainly because the ROI dropped & I was extremely busy.

By that point I had paid off all the rigs and made several thousand dollars so I was pleased.

I still had 12 fully functional computer systems (I used AMD CPUs with onboard graphics so no GPU needed)... many of which I started using around the office at work.

Earlier in 2017 I popped back into the forum, saw the Nicehash program, and started again... only had to buy 24 GPUs and no new systems so ROI is super fast this time around. Since I had already paid off all the "base" systems. Mining on them hasn't interfered with their usage as office PCs either... nobody can really tell other than some fan noise.

It's been fun enough that I have built a few completely new rigs using the funds from mining as well (up to 36 total GPUs mining now across all the systems I'm using).

Long story short... minus a huge crash ROI shouldn't take more than a few months. Buy decent hardware that will last, though, IMHO...

Stuff that has worked for me... Rosewill PSUs -- good reliability & when I have had a failure their warranty service has been stellar. I keep a few spares around so I'm not down if one does fail (watch Newegg they have crazy specials on Rosewill PSUs pretty often). ASRock motherboards (mid-level not the absolute cheapest) -- All 12 of my original rigs use them. I've had one failure in 4 years & on that system I was also CPU mining to experiment -- great price point and I've had amazing results. Use decent quad-core CPUs... I built one for a friend with a dual-core and it's extremely laggy and annoying to use plus better re-sale value on the quad cores.

Mining is dangerous ... but as far as I know, it's always good !

I started in late 2013 with LTC and BTC rocketing ... I earn money !
Then LTC was saturated, I switch on dogecoin ... I earn money !
Then I switch on Darkcoin (Dash) ... I earn money !
It has been a low profit period (late 2014/ start 2015) before the ETH comes ... but with ETH, profit again !
Then ZEC coin ... I profit again !


The crypto currency market is waving, but every time I got a doubt on the profit, the situation has come back few time after (sometime some months ...).
So right now, I'm still mining with a electricty cost of 0.16$, wich is really high for a european country (france) ... But I still manage to do some nice profit every day.

So ROI, is just a matter  of findind the good coins to mine, and hold it while it's low to sell it higher
Back in the days I was mining 10 Dash/day or 4 Eth/day. I hold a good part of them (and get robbed a good part ... thanks Cryptsy !)

Investing in rig is not a bad idea as long as you still got "real" things to sell if something gone wrong (Old GPU or PSU can still be sold if you have invested 3k$ in it ... but buying a 3k$ in coins and the price is divided by 4 ... you got only your eyes to cry )

my friends ~3K investment in gpu rigs nets him currently a little over 1K/mo.

He did wait for people selling cards at a deal.

Typical GPU rigs ROI in 3-6mo.  in today's market, as low as 2 months.  but that can always change drastically.

Hi guys,

Very interested in some kind of mining rig set up...  

My first question is, is it possible for a few thousand dollars to build/buy something that can NET you $400-$500/month? Or what is realistic these days for hardware that can give you that kind of profit. My electricity costs is about $0.12/KW/h


I've been going through these forums and others and can use a bit of direction on mining rigs worth considering...

If YOU had to start all over with a mining rig (GPU based), what would you consider in the following categories:

- as a build-it-yourself? Whose set up seems to be the best these days with fairly easy to follow instructions?

- as a pre-built solution? Who are reputable vendors to consider?  I've been looking at parallelminer.com, miningcave.com. eBay seems to also have some sellers who sell full rigs.


Also is there any reason to prefer either NVidia or AMD GPUs or will either work well.


Thanks for any direction or advice you can offer.
