There are a few guides out there. I did one a while back. Powering up gives you influence through votes and witnesses as well as earning for you. Converting to cash can be tricky depending on where you live, but it is possible. I have a crypto debit card from Wirex.
Hive can be fun as a social platform if you find content and people you enjoy. I get frustrated with the other platforms.
Thanks, I will read it all later. So much info there and prefer to be on desktop and with my full attention.
