I have a mini pc raspberry pi3. I use it already for earnings. I get a couple of coins on it: the universe(uni), bitradio(bro). Can you advise any alternatives for this PC with greater profit. And there are those who run on it more than 2 wallets. Interested in your opinion.
It seems as if you are staking your coin and not the POW mining we know of, so what is the amount of profit you make and why don't you just make use of a vps to run the wallet in there and stake your coin instead of using your PC and leaving it on all of the time when you can use that time for doing something even better. If it were to be POW mining, then I would have told you to make purchase of a miner but since it's not, I think the best you could do is to make use of a vps instead of running it yourself.
