It's possible but right now with prices being way down it's simply not possible with hive unless you're one of the few that are getting $180+ on posts and then some curation rewards. The big issues half is instantly locked in for 13 weeks! So that $100 you just earned only about $50 of it is liquid for you to do with what you want.
However if LEO returned to $0.25+ again and hive over $1 and they both held steady I could see that being possible. One thing I love about LEO is it's starting to bring value INTO hive through fees, ad revenue etc instead of being 100% reliant on supply and demand. It's something I hope I see more places do.
@reward.app solves that locked up problem quite easily, it liquefies the post rewards for a 1% fee (and 4% for the curators in the default setting)

The 100$ income stream that I'm talking about should happen not only through blogging but also through other means. Like playing games. DeFi on Hive and many other things.
