I havent tried it yet, but based on the hashrates listed in the readme.md file for Trex Miner, it doesnt look to be all that profitable. Overall based on those numbers Im losing about ~5% of my profits if I just stuck with LHR 70% on Ethash, or 100% RVN. Didnt look at ERGO, but I would imagine its similar.
But as I’ve said, i havent done any test. Just using the numbers they have provided for the 3060 LHR.
