Topic: ROI question on mining rigs (Read 7713 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 -

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!
