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?


Cash withdrawal / Prepaid cards can be traced back to me and I would like to avoid them if possible. As I said electricity is cheap but I would like to know the reward to effort ration for a PC like https://linux-hardware.org/?probe=578a7e4ccf
How is cash traced back to you? And you can pay cash for a prepaid card so the transaction is pretty anonymous.
I haven’t followed the coin you may be using but recently bitcoin were hitting the reward is not with the cost of gear and electricity, causing miners to move to something else. I think that is by design of how cryptoworks, you eventually reach a stasis of mined coins
withdrawal can be traced.
They don’t know who you gave cash to if you take cash out of bank and then send via mail, money order etc
Cash has unique id to reach bill, which can be logged on withdrawal, final point of reentry system can be logged. Of course, everything in between is unclear. But with enough re-entries at various points in time, a fuzzy picture is possible. Especially with multiple sources of withdrawals going through a common mid point.
