Can those bitaxe 601 run on pools, attributing small amounts each day? Or is the amount going to be this small, that it's definitely going to cost money?
I think Ocean allows withdrawals in lightning, so you can get paid small amounts. It's definitely not worth it, though. If you're going to mine, at least go for the big bucks solo.
You can do a bunch of things with it. First of all you can learn how mining works in practice. You can hope to win big. You can turn evil and try solo mining something else with SHA256d like Bitcoin Cash, which IIRC is something around 200x easier / more probable to do (you have around one in 70 annually to win 3.125 BCH ~= 1300 EUR). You can setup a mining pool and see blocks being actually mined in testnet.
You can also decorate your place. Look at this beauty:
