I have 3 RTX 3070 mining, and I can confirm I get 60-62 hash. Grabbing me $23 a day :)
And what is the cost of electricity you are consuming? And the cost of changing your cards when they die mining? The damage miners do to the gaming market and to mother nature (power usage is too much) is just intolerable... just to get a few bucks I get doing nothing at all.

To answer your question in a month my light bill has gone up by $10... and I am making about $450. Explain to me what mother nature damage I am doing exactly? Think of having the lights on longer... As for the damage you do to your cards. These cards are meant to be used not to be gentle on, playing games none stop on it will produce the same wear and tear. If anything all you have to do is put some more thermal after 2-3 years... So the "few bucks" are actually big bucks when you do the math ;). Don't get mad because you aren't part of the game. Also in the 20 years I've had a PC and gamed, not once has a GPU died on me. And the 15 years I have working in IT I have yet to replace a GPU in the field. PSU is what will die more on you.

As I am also interested in his point, I will re-ask his question in a slightly different way. What is the KWH rate for electricity in your currency? And please specify the currency.

Maybe this will make it easier for some who don't really know. This is my current setup with 3 GPU (3070) at my cost of electricity. I'm not including the extra $2 a day I get from mining the CPU also.

So way less than half what we Oceanians pay... Makes the mining a bit less profitable. I would have to add about 100 USD per month to my expenses. Doesn't quite have the same appeal at those rates...

Oh gotcha. Yeah there the profit is there but much slimmer. I know countries and states rates varies.

Add to that the hugely inflated GPU prices down here

Add to that the hugely inflated GPU prices down here. I would be lucky to get a 3090 for less than 1800 USD. Basically, add 800 to 1000 USD to any card's MSRP. Just doesn't seem to be profitable enough stacked up to the potential for crashing coin value during the pay-off period.

Because crypto is by its very nature such a volatile and unpredictable sector, graphics card manufacturers won't take the commercial risk of producing bespoke mining-only GPU SKUs, and crucially, ALSO gimping the hash-rates on their GPUs intended for gaming, which would be the necessary two steps to see that miners were compelled to purchase cards fit for mining and only mining, whilst gamers could get their hands on products that were only compelling purchases for gamers and no good to miners. Miners would have to wear their losses if the crypto bubbles popped or when PoW switches to PoS, they wouldn't be able to flood ebay with clapped-out GPUs at ridiculous second-hand prices, because the card would be useless to gamers. They need to make their cards as attractive to as many people as possible, at as high a price as possible (to wit, Nvidia apparently scoring an "own goal" and breaking their own code for the 3060 to enable high hash rate mining on it by "accident"...a likely story!). This all tells me that the GPU manufacturers don't care WHO buys their cards, or that they're paying through the nose to do it - the only thing that matters is that the stock is going UP, UP, UP....

More inaccuracies.

And on reading the rest of your post - wow, the voices are loud today, eh?

My point is that you have 3 cards instead of one. You took 2 cards away from other 2 gamers (because SLI is in decay). Like you millions of miners do the same thing or worse (tens of cards). Do the math and you will see why video card availability is an issue and why the prices of video cards are just insane. Besides, consuming more electricity with mining directly affects mother nature. Regarding this, check internet about why, please.

I like how people count their crypto profit only on electricity costs. Do not forget that crypto is taxable and you must pay taxes or you will have problems with IRS.

CPU mining is a really bad idea... Heck! Even at $0.05 / KwH I've decided to stay away from this. At this point, it becomes a waste of natural resources...

The damage gaming does to nature is even more intolerable. Time to ban your hobby.

Sorry but I have only one card (gotten after a three months wait and for double the price), and the company who created it made it for 'gaming' (not for mining). I am gaming only a couple of hours by now because I have to work harder. I am not stealing cards away from other people in order to make a few bucks I can make in another way. I do not believe in crypto and its bubble. I just believe in hard work.

You make airy pronunciations about how mining as a collective damages nature, to individual miners. You don't get to wriggle out saying "I only have one card!" wrt gaming, thats complete hypocrisy. Gaming uses up a lot more carbon credits and produces nothing but self-gratification.

As for your beliefs, I really don't care any more than if you told me Earth is flat and vaccines cause autism. All of those statements are equally true and equally wrong.

And what is mining producing? Nothing too, only more bubbles. When the 'pin' appears, you will see. But the point here is that if the miners want to continue with their craze, they should go and buy mining video cards and stop stealing cards away from pc gamers. I never damaged their 'crypto bubble' but they are damaging my 'well deserved' (after many hours of hard work) hobby.

Crypto IS the pin. The bubble is the current financial system and your fiat money.

You not using your cards to mine is influencing absolutely nobody. You could've had them both paid for themselves if you weren't so thick headed.
Yep there are two issues here. Crypto inflating GFX card prices for gamers which frankly sux. Then there is the economy for youth - housing, wage growth, you name it. It is trash. Crypto beats the wall street and big business bs.

Wealth inequality is absolutely staggering. Crypto is giving people a way out of that system that has utterly failed the majority of poor and much of the middle class nowadays.

When the first crypto mining billionaire pops up, let us know.

Question... How much money do you think the one that owns these have;


Let's do some basic math... You want a crypto mining billionaire. Ok. So, right now, let's use Bitcoin as a reference. Let's say Bitcoin is $60k USD. In order to be a billionaire, the miner needs to have 17k Bitcoins, rounded up.

Next... Around 900 BTC are created per day. Assuming the largest miner has about 3% of the total hashrate, that would mean they would get around 27 BTC per day. That's about 9500 BTC per year. That would mean that in less than two years, one would be a billionaire, if there were no expenses. Obviously those are there... But... Considering the amount of time we are talking about here... I don't think it's impossible to become a billionaire through mining, if you already started a while back...

Also, take a look at the addresses with the most Bitcoin... How many Billionaires are there...? Obviously we don't know if they mined them or not, but it would be hard to believe that there are no miners among all those;

And if the price keeps rising....

For gpu crypto mining I'd never buy RTX(or amd 6000) cards: why pay for RT/tensor cores which are 0 profit. So only used gtx/rx cards make sense if you get 'em for mining only. RTX 3090 is absolutely insane: paying $$ for 24 gb is pointless, you only need 6-8gb. The best is Radeon VII :)

Some of those numbers a bit off, too. A Radeon VII will not do 95-100 MH/s for 200 watts on stock bios. You'll top out at around 90, if you keep the power limited to 200w.
no, it actually does even more: about 102-103 with small gpu oc and reduced memory timings, on linux with latest TRM(0.8.1), proper gpu undervolt. I get stable 101-103 mh/s depending on temps, see TRM ethash tuning guide. Sensors report 190-195 W power1.
