Thanks for this analysis! Even "passive income" takes work to make it happen to your best results. I've gotten into renting my cards lately and it is a monotonous chore but nice to see the DEC roll in. And nothing could be easier than hitting the CLAIM button and collecting those SPS and staking rewards daily.
I only post once a week, it's not nearly as profitable for me as it is for you so I spend a lot of time commenting and trying to build relationships to get my blog a better following. All that takes time and consistency, but I do enjoy creating posts.
