3 years into crypto mining — should I continue?

I’ve been into crypto mining for about 3 years now. I’ve tried a few different projects, mostly ones that don’t require any investment.

To be honest, I haven’t made any huge amount from it so far. I’ve just kept doing it whenever I have some free time, mainly because I’m curious to see where these projects will end up.

But after 3 years, I’m starting to think whether it’s actually worth continuing or if I should just quit and focus on something else.

Anyone else here been mining for a few years? What’s your experience?
