Mining crypro doesn't materialize money. You have to exchange it for real money which means taking a private individual's money in exchange for scam tokens.

This is the problem crypto fans refuse to acknowledge. The money doesn't magically appear, you're taking it from someone else and letting them hold the bag when whatever cryptocurrency you choose inevitably blows up, fails, or rug-pulls. It's unethical to engage with at all because you're still participating in scamming real money out of private individuals

The problem is that much of the cost is borne by humans accessing the sites. People generally get real mad when they find out you’re using their computers to mine crypto.
