I have the small doge miner, not profitable but runs fine.
Nothing is profitable right now but you are doing great that you are running the machine,usually Goldshell devices if you have a mini one do not consume a lot of energy and I think this is the strongest selling point of the Goldshell manufacturer.
You will thank yourself later in the long term in the next bull run as long as you keep the miner running and your DOGE number increasing everyday,that is what I call a win and well done to you.
