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?


Yeah agreed. Even if cashiers had a tracker for bills you still have general population chaos. Like I take 20 out of bank (tracked). Say I paid a friend and they bought something (tracked) then you have some rudimentary contact tracing/location, however: I could take out 20 (tracked) and ask a homeless guy if he’d give me $18 in change, bills and coins for a $20.
Now my transactions just disappeared, if the homeless guy immediately buys something you have some tracing and location, but you know how life is: money slips from his pocket, the wind blows it a few blocks away, a guy from out of town finds it and maybe mails it to a relative as part of a birthday card, that sits in a kids piggy bank for a year. Spends it and it’s tracked…but that data connection is a mess to try to work backwards to the withdrawal
