Topic: I'm looking to spend $40,000 on mining rigs. Any suggestions? (Read 3725 times)

I can easily buy 5 580s a day through that website that alerts you when they are in stock, same goes for the 1070's...its not hard at all to buy them anymore since the summer.  Also you can go on that other auction site and see people selling them in batches of 10 or even 20...THis is the best idea to mix up the cards and get some 1070's into the mix...Question though...why would an 8gpu rig have a lower cost than a 6 gpu

what is vega dual mining eth and dcr/ lbry ?

my suggestion is to stay away from mining, buy the coins and enjoy 10x the profit in few months.

Why not get a vega at the same price? Power draw is a little more but it gets way more hash in monero and dual mining.

All comes down to electricity price - if you pay like 7c/kW or less then gtx 1070 is probably the best option.

When the OP posted this it was a poor time to get in to mining, profitability has dipped ever since.

Did you spend the money at last?

I was looking at spending about as much as you initially with a new mining operation, but it looks like its going to fall through as it's simply more profitable & less risk to simply invest into the coin at this point in time. Especially with increasing difficulty and coins moving away from PoW.

If you are looking for used products, I have a mobo Z97 gaming 5, around 13 risers, ssd and celeron cpu. I have used 7 gpus and sold my gpus recently. The mobo is a legend in mining field.

For me the ROI is really fast if u know how to cut down your hardware cost and  how to get your new Rx570 and 580 series  GPU @ official AMD cost price which is between $200-$220 which is pretty easy if u have a very good website like the one I always use for price alert update to get stores and website offering clearance sale and buy the GPU once in stock when u get the alert , anyway if u need the website alert to get your GPU, u can email ( [email protected] ) me for the link

1070 is the best. It will retain its value more than 1060.

Im not looking to spend $40 000
but i need a recomendation

im building a rig and cannot decide

4x 1070        $ 2151   120 MH/s   $432 /month     1880sols   $369 /month
5x 1060 6GB  $ 1807   117 MH/s  $429 /month     1650sols   $317 /month
6X 1060 3GB  $ 1743   135 MH/s  $500 /month      1770sols  $340 /month

as much as i would like to buy cheapest version with highest profit,
i am also concerned about the selling price later
not many gamers will like 3gb version of 1060 even though 6gb is not a big difference on 1080p res.
and 1070 will probably also drop in price quite a bit..

but im thinking, 3gb will not become obsolete for mining before ETH hits POS so i should be good then, and even then i should be able to mine zec at higher hashrate with more 3gb 1060s ?

ICO is more stupid Investment rather than mining and the coin you are not sure that it's legit. Mining is the most safe yet profitable compares to ICO that pure POS and very risky once the project you involved turn to scam.

 invest 10 $

in how to make profit with ico coins like

save 39990 $

make billions...

simple isn't ?

not against mining... i like mining but, it is a stupid investment

It's crazy, $4000 is fine, I think.

Buying ETH right now will give at least 100% in a month or so. ETH will soon hit 0.2 btc.

gemeni is fast

Good luck getting verified in under a month in any exchanges right now

To answer the question, it's vital to know your electric cost.  If more than 10 cents per kwh the answer is simple.  Don't throw away your money on hardware that will almost certainly never make enough to pay for itself.  It's impossible to accurately predict how long for a ROI for a new rig now.  All we have is past profits which we know are useless at predicting future returns.  Prices are falling and difficulty is rising leading to rapidly declining profitability. 

In a few months, certainly before the end of the year, the only rigs generating more revenue than they cost to run will be those running the most efficient cards on the cheapest electric.  This is not wild speculative guessing.  The recent high returns were demonstrably unsustainable.  They relied on rapidly rising prices.  The speculation driven bubble is bursting and cryptocurrency prices are falling.

Mining should be viewed as a hobby.  It's a great hobby and it doesn't matter if you make money or not.  But if you have $40k to invest, you would likely do much better buying and holding the coins themselves - especially as they return to more normal levels.

Taking into account rising difficulty and falling prices, ROI is probably measured in years rather than months, and even then only if you have cheap electric.

Good post. I would agree getting in right now if it's not "disposable" money is very risky.
