Write down the cost of electricity and calculate your return on investment. Only I advise you to increase the result by 2.5 times, because after the end of Ethereum mining, everything will change a lot.
Thanks for your reply!
I live in Switzerland. The price are in CHF.
I do not have any cost of electricity.
The RTX 3070 would be less than 1000 euro. It is a good price for you ?
What case do you suggest ?
