Got it.
Thanks for the comments.
Taking advantage of the topic, I was comparing the results on the website of nicehash and minerstat. both using the same card and the same energy cost.
the RTX 3070 that I intend to use, in nicehash presents usd4,63 of profit and in minerstat usd6,12.
Is there such a difference, or should it be some wrong calculation of the site?
Nicehash mining calculator is very accurate just like that of whattomine website, I'd stick with nicehash is I where you, there are other minable algorithm on Minerstat maybe that's why it's giving high rewards through calculator, my advice is never mine any coin that's not well known, you will have better results mining Ethereum
