Hi,

I've managed to build 2 mining rigs, each with 6xRX580, but I'm a beginner when it comes to mining.
I've started mining using NiceHash - CryptoNight, but the revenues are kind of low and the fees are high.

Could you advise me on what would be the best thing to do for mining with 2 rigs of 6xRX580 cards?

Thank you in advance.
