I understand what your saying. Steemit is mainly know for author rewards for posting and curation rewards for upvoting. Few people have read the white and blue papers to understand that like POS tokens DPOS tokens provide in wallet staking and through a feature called Delegation your investment can yield up to 30% return passively with no posting and no upvoting. You just delegate and your done.
While I would love to see additional DeFi applications I continue to promote what we have here already via my Steem-Staking project. Link
