If you have a your own Bitaxe already and are looking to just generate a few sats per day income by running it, I recommend https://braiins.com/pool - I have a few Bitaxes already set up to use that pool and I few sats sent to my lightning wallet daily. You're not going to get rich by doing it this way, but you are contributing your hashpower to the bitcoin network, and you see a (tiny) daily reward for doing it.
