Quoted from Astropin:Is mining really more profitable than just throwing money at it? Or is just the technical "thrill" of it?
There is definitely some thrill in building your own computer/rig.
As it sits, you can get into it right now, but you'll be paying between 2x and 2.5x the retail price for graphics cards. There is speculation that once Ethereum goes PoS (proof of stake) everyone will dump their GPUs/ nobody will buy them. Last I checked there are more than a hand full of coins available to mine haha. (Decent GPU up to $600 was about $350 or $300)
For my recent builds I spent more money on the CPU because I wanted to maximize the ability to mine Monero. Basic CPU that is good for gaming is about 250-300 but I went for the Ryzen 9 that comes in around $500. Then add $100 if you want to overclock and give it a proper cooling system.
Memory about $100, a computer power supply $50 to $60 but if you want more than 2 GPUs on your computer you'll need a server power supply so that's $150 easy.
Motherboards easily around $95-150 for something respectable.
Accessories like PCIe risers and computer case about $50. You don't really need a computer case if you don't care. If you refurb a tower that saves some money. You'll want to replace the tower fan with something nice (and quiet) that's only $20.
You can get a SSD drive pretty cheap. SATA or M2 is fine. I like M2 it's less cables and less mounting to worry about. I am told Window's 10 Home Edition throws up a lot of wrenches if you try mining. I'm using Windows 10 Pro. Enterprise will work too. You'll need software/license key for that. I won't disclose what I'm paying for mine because I honestly don't know. I've been buying them alongside some other parts. But all of mine are legally licensed with the stickers to prove it.
NOW we can talk about an important cost.....electricity.
Right now I'm at $0.09 per kWh which is average and still makes it worthwhile. Starting in June we're looking at 12 cents per. At this point you better hope your coins appreciate. Anything more than this you might not want to bother. One computer with 1 GPU can easily be like having an incandescent 100w lightbulb on all the time. Maybe 150. My current estimates put each of my computers in at earning $120 a month assuming all the coins stay flat.
Hopefully you can math better than I can. If someone told me these coins wouldn't appreciate I wouldn't have done what I did.
