Cryptocurrency at Wikipedia: "A cryptocurrency, crypto-currency, or crypto is a binary data designed to work as a medium of exchange wherein individual coin ownership records are stored in a ledger existing in a form of a computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership."
I've successfully sent a share, how much money is its value? Nothing. If the pool completes a block it will be rewarded in crypto depending on how many good shares you have sent in the last N shares.
Our pool finished a block. There are 100 miners. How much money will I earn? Nothing. The block has a reward in crypto and this is divided in miners depending on which miner how many shares sent in the last N shares - minus pool fee.
I can say that not, not with my PC, but maybe with a faster high end PC, or with the special miner machines.
I have tried with my PC, I've used xmr mining at background while I did my usual computer tasks (emailing, browsing, photo and pic editing and gaming too) maximum 12h/day, my CPU can mine maximum 0,005XMR/month. Every task was a bit slower, mostly I cannot realize that something else is working hardly, but electricity bill grew a bit, so I can say I waisted energy...
I've also tried to make my NVidia card to mine profit, but it uses extra power and it is also not enough fast for profit.
Don't forget the amortization, you have to earn the periodic hardware changes (at least the cooling system renewal).
And in 2022 the crypto's value in EUR much less than 2021 but the energy prices is much more at worldwide. And one more important thing, that not every trader/exchanger are fair, some of them keeps your crypto and won't pay its value.
Also you have to make the decision is it worthwhile for you or not. It is free to try:
Under Mageia Linux I can tune up CPU-XMR-mining with enabling huge pages. It yielded me extra ~20+% on hashrate when I've created /etc/sysctl.d/51-xmrmining.conf:
# This file for speeding up xmrig and XMR mining sw-s # Enable huge pages for xmr mining: # - Randomx allocated 2336 MB (2080+256) huge pages 100% 1168/1168 +JIT vm.nr_hugepages=1280

If you have a better graphics card in your computer you can grip it to mine XMR.
NVidia and AMD GPUs also capable to mine other cryptocurrencies (you may need other miner sw and wallet), don't forget that your VGA may use extra 100+Watts for this job.
As Monero is for CPU mining other cryptocurrencies is more effective or designed to mine with GPU. If you would like to use your VGA you should search about ether-based and other cryptos.

River fishing is an interesting way to catch fishes in a flowing water...
Me and my friends spent good days at Lake Warali in Baja.
I tried different Lake, they say there are big fishes. Every time I had fished here I caught 4+ carps too.
I'm working on a CMS for develop my PHPskills.
You can buy USB FLASH DRIVES and MP3/MP4/MP5 PLAYERS with FAKE memory sizes on the Internet!
