I still believe that, at least if you want to make the most NIM in a short period of time, while the GHR is still low, renting cheap dedicated servers for like a month is your best option, or get free Azure/GCP credits and mine on those, but it will take multiple accounts to get a decent amount of NIM
Do you mine on a dedicated server? i want to give a try, but i'm not sure which one to go with. i'm not sure about mining on Azure, they will ban the account if they noticed extensive cpu usage.
