No it may be some hacked version or whatever but Ethos is only available from gpushack.com legally. But if you are going to buy a license look at more modern oses. I am still a 25+ rigs on ethos....i have 60 total...but old rigs are long since roi’d and gone.
Hi!!how do you plan to support epoch > #384??
claymore doesnt support it... and the other miners on ethos are very old (trm, lol, etc).
For my new rigs rx5700xt (i'm small miner) I use raveos (up to 3 free rigs), but my old 3 rigs (rx580) are on ethos and somewhere near end of 2020 will be unfunctional.
