I mine cryptocurrency and make about $110/day. I have two L3++s, an AvalonMiner 1246, six RTX 3080s, an RTX 3090 and a couple older cards. It more than pays for the mortgage, and after electricity (residential rate) my profit is about $100/day.
I also have the GPUs in a grow tent (designed for growing marijuana) with an 8 inch in-line fan hooked up to the supply of my home’s HVAC system. I’m heating my whole house with cryptocurrency and saving about $80-100 per month on gas (furnace has been off all winter).
- rfd4sgmk8u 5y agoThat's the way! Nicely done. Can I ask what your power costs are? The problem is that in high population centers in the US, electricity costs make it not economical.
- adossi 5y agoPretty typical $0.1/kWH (on average, there are peaks and valleys like everywhere else). A lot of folks overestimate the actual power cost. Sure I’m pulling about 24A at 240V from the wall (over 6 kW) which costs somewhere in the neighborhood of $320/month. But the actual BTC I receive is worth over $3000/month assuming I sell it as I get it. What’s super nice about mining is that it’s quite resilient to market trends. For example if crypto crashes 50% the number of transactions on the blockchain skyrockets (everyone either buying the dip or panic selling) which results in more cryptocurrency actually received from mining. The value of the coin can go down, but I get more of it. As a passive revenue stream it’s actually quite beautiful. Just don’t forget to pay taxes!
- rfd4sgmk8u 5y agoThank you for sharing the numbers! That does look quite profitable even for a hobbyist (maybe even YOU, the reader?). I am all for the further decentralization of this technology and hope others can profit from this also!
- alphabettsy 5y agoHow much did the setup cost? I saw a similar post where the poster was making a decent amount but wasn’t yet profitable because of $30k in startup costs.
- adossi 5y agoI started small, let things pay for themselves before buying more. My initial investment was about $10,000, and that was just for a handful of GPUs, some parts like motherboards and CPUs, an electrician for the 240V 30A line, PDU, etc. Once I made that money back I slowly bought more. My most recent purchase has been the AvalonMiner which will pay for itself in another six months or so. If I include the revenue from all the mining hardware though, the AvalonMiner will be paid for much sooner. It’s funny how that works :)
- aerovistae 5y agoBiggest question that comes to my mind - if you can make this profit so consistently, why not triple your rig? Or even x10, or x50?
- waynesonfire 5y agoRisk? There are folks doing just what you describe. Everyones capital and risk levels vary and so you get miners on gaming rigs with single gpu all the way to those buying fuking coal power plants. Where would you land?
- adossi 5y agoThat’s the plan! But I’m already at 80% maxed out on a 30A 240V breaker. Sure I could add more breakers, but I really don’t want to turn my basement into an industrial mining zone (not to mention the HOA might have a thing or two to say). I’ve already used some soundproofing (Rockwool) in the room that all the mining equipment is in, the noise is real! Also I need more airflow, I’m exhausting extra heat out a small basement window. If I want to expand I need to consider intake fans from a second window to keep airflow moving seamlessly. I’m in a peculiar position where if I lease out a warehouse for $3000/month I literally deplete all the profit and break even until I expand more. I’m not sure where to go from here, suggestions welcome! So far the best plan I have is just wait until I can afford a bigger house with a big backyard, so I can build a mining shed out there.
- epolanski 5y agoI hate what you do (the very idea of all those KWs going to solve sudokus to get monopoly money) but at the same respect you. In the end if someone buys, why not sell.
- bee_rider 5y agoI don't believe in cryptocurrencies, but I don't see anything unethical in a spaceheater that also does hashing as a side effect I guess.
- lkbm 5y agoThe people in my house use space heaters in their rooms. 1500 watts of electricity produces 1500 watts of heat whether you do it via a space heater or a computer. The only way OP's method is worse is the capital costs of the processors. The energy spent on the actual heating is converted with 100% efficient either way.
- joshlemer 5y agoWell, except that only works in the winter time.
- jack_pp 5y agodepends on your climate, my home needs heating like 8/12 months and gas prices have just surged more than 6x since last winter
- Kerrick 5y agoOur house is electrically heated via a heat pump, which has appreciably more efficiency than a resistance heater (or computer). Here's a neat video about them: https://www.youtube.com/watch?v=7J52mDjZzto https://www.youtube.com/watch?v=7J52mDjZzto
- lkbm 5y agoYeah, a heat pump is definitely better if you have it. My point is that if you don't, mining provides the same energy-to-heat conversion ratio. My house is from the 1800s and only has heating for the kitchen/dining room/living room.
- agustif 5y agoI was looking into just getting a 3060 Ti for starting on my main CPU, do you recommend that or going for whatever gets a bigger hashing rate in one unit like the 3080 or 90 it seems, they are hard to get! Thanks!
- adossi 5y agoI would personally aim for non-LHR cards like the founders edition 3080 which is hard to find these days, or any 3090. At the end of the day it doesn’t really matter what cards you buy, what matters is your ROI. For example at MSRP a 3090 can pay for itself in six months (or whatever it works out to these days) but at scalper prices that ROI time is more like a year. In the world of ASIC mining a year ROI is actually not bad at all because the big industrial ASICs can last 5-10 years. Then you have helium miners (HNT) that can ROI in 3-4 months. It’s all about the ROI.
- tough 5y agoYeah damn, they're on 3k now... Maybe a new 3090ti if I can snatch one at MSRP, but don't have the money anymore for it... Was also looking into filecoin mining, but requires lots of HW (would have to buy at least a graphic card, 64gb ram, and lots of disks lol) and you've to pledge/stake money too for each block or tb committed to serve... Looks like a hassle but high returns, so anyone with more budget than me and enough technical chops, might be inclined to look into that! Just saying Thanks for all the info, got me into a lot of research, for now I'll keep on the build camp
- W-Stool 5y agoCan you ELI5 how making small amounts of money in crypto works? I thought it was a "winner take all" kind of arrangement where whomever solves the "puzzle" (for lack of a better word) first gets all the bitcoin as a reward, until the next block is up and ready to be solved. You're talking about making $100 a day - a very tiny fraction of one bitcoin - how does that work?
- artdigital 5y agoBarely anyone mines alone. You join a mining-pool, so your hashrate gets added to that pools hashrate. When the pool finds the next block, everyone gets a share proportional to their contributed hashrate
- downandout 5y agoYou can contribute mining power to a large network of miners and get a percentage of the profits. They are called mining pools. These exist for virtually all currencies. Here's a list for bitcoin: https://www.buybitcoinworldwide.com/mining/pools/ https://www.buybitcoinworldwide.com/mining/pools/
- iampims 5y agoMining pools split profits according to each participants contributions (~= hashrate)

- adossi 5y agoBitcoin is highly divisible. When I say $100/day what I really mean is something around 0.0016 BTC per day. This number fluctuates a lot so it’s best to look at the average over a week or month. The best way to learn IMO is to try it yourself with your gaming computer. I personally use a platform called NiceHash (not sponsored, nor am I advocating for them, there are alternatives) which pays out in Bitcoin. Try it out yourself, depending on your GPU you could be making $3-10 per day. Run it for a month or two, or longer. Transfer that Bitcoin to an exchange of your choice (Coinbase, crypto dot com, etc.) and sell it for cash. Then use that cash to buy more hardware (or beer).
- quickthrower2 5y agoNice thats a lot of profit! Is there a “catch”? Are you getting super cheap electricity. Whats the depreciation like on the gear per day?
- adossi 5y agoThe catch is you need to be safe: - Where is the heat going? Are you exhausting it out the window? Are you going to burn your house down? - How are you distributing power? Are you using a PDU and a 240V 30A breaker or are you maxing out several 15A 120V lines? - Is the humidity dropping rapidly to dangerous levels, risking shock? Are you going to fry that brand new $10,000 ASIC miner because you dried out the air too much? - Did you short out the GPU pins removing a GPU from the socket? Did you just cost yourself thousands of dollars? Safety is important not just for yourself and family but you need the hardware to actually survive. If you have a bunch of 3090s that just finally reached ROI 9 or 10 months in but the cards themselves just died, you’ve effectively broken even after all that effort. Surprisingly GPUs are quite resilient so long as you’re not massively overheating them, and you open them up every now and then to replace the thermal paste and perhaps thermal pads. I have a monitor visible at all times that displays all the temperatures, and I have one eye on a humidistat making sure I don’t suddenly drop below 30% relative humidity on an unseasonably dry day. There are lots of resources available. If you’ve ever built your own PC you already have like 80% of the knowledge you need.
- raegis 5y agoDo you shut it down when on vacation? Or hire someone to babysit your machines when you're away?
- adossi 5y agoI left it running while on vacation for a week recently, I was incredibly paranoid the entire time and I probably wouldn’t do that again.
- quickthrower2 5y agoThanks. This is actually what has put me off doing it. I don’t want an unsafe thing in my house! Also its the type of engineering problem i hate most - one where you meed to monitor 24/7 and all sorts of things can give you down time, but you cant really make it perfect because that would be too expensive.
- flippinburgers 5y agoWhy not mine more if it is this easy? What are your electricity costs?
- csee 5y agoWhich crypto?
- fapi1974 5y agoFor that setup, what is the up front investment in equipment?
- jcims 5y agoFor me the question is how to get comfortable with the mining software stack and the pooling services. I poked at it a bit earlier this year and, possibly just due to my own paranoia, I felt like I needed to take a shower afterwards. I don't know why, I just felt like there was no ground truth from which to build a framework of trust in the tooling and the services and I was suspicious of everything.
- adossi 5y agoIn the world of cryptocurrency and cryptocurrency mining you really have to wade through the mounds of sh%# and scammers. In terms of trustworthy sources here are a few trusted YouTubers that are very experienced, they taught me a lot about mining, mining safety, and general crypto knowledge: ChumpChangeXD, Red Fox Crypto, Red Panda Mining, brandon coin, Son of a Tech.
- jcims 5y agoThis is super helpful, thank you!!!
- IAmGraydon 5y agoThat’s a $30,000 rig at least. So 300 days of mining before you just break even. I’m sure that in 300 days it will only be able to mine a fraction of what it does now due to increasing difficulty. I’m not seeing how this truly works out.
- adossi 5y agoYou are grossly overestimating the depreciation of mining hardware. It’s pretty common to have well maintained mining rigs and farms that last several years. Also, it’s a common strategy to sell mining hardware at or near ROI time to essentially double your initial investment. Coincidentally my GPUs have not only paid for themselves and then some, but I could sell them used now for more than I bought them for. I’m lucky in that respect.
- dehrmann 5y agoThis is a tricky time to try to read the tea leaves on GPU depreciation.
- fny 5y agoThis ends when ETH2 arrives.
- adossi 5y agoMining ERGO and RVN are profitable also!
- steve918 5y agoWhy would miners just move somewhere else?
- doopy1 5y agoI doubt most of these folks are even mining eth.
- rfd4sgmk8u 5y agoHe has quite a while then....
- TameAntelope 5y agoMy 3080 paid for itself, but I stopped once I hit that threshold due to the ethical concerns I have about the negative environmental impact of proof-of-work mining. The community is not very trustworthy, but the software is actually really straightforward once you figure it out yourself.
