Is there a realistic way a person having an old computer and cheap (but not free) electricity can actually mine monero equal to some amount which can be used to donate to good service providers or purchase services?

I keep hearing about low reward to effort ration, but can I get a respectable amount in let’s say a year without having to deanonymize myself by going to a Centralised exchange?

What search engines and networks do y’all visit when searching for what you need? The search engines on fmhy.net just don’t return the right results and I have to !s on a network’s channel to find out…

EDIT: It seems like I just got unlucky, https://xdcc-search.com/ works mostly, atleast for rizon
