Where can I find a manual or a guide that explains how to mine aeon with the daemon? What alternatives are there to mine aeon?
Using the daemon you can solo mine, and it's quite simple. Just sync the daemon, open and sync your wallet, then type:
start_mining <number of threads>
Except replace with the number of threads you would like use, probably 2 or 4.
You can also do it without even starting the wallet, just the daemon as described here: How to solo-mine Aeon?
