Well said. Investing your time, knowledge, effort, and money into Steem is the best thing you can do.
One of the most interesting parts of the Steem whitepaper is that they call this system "Proof-of-brain." In Bitcoin, you donate computing power or computational work to the blockchain for rewards (proof-of-work), and in some other cryptocurrencies you donate/stake actual coins for rewards (proof-of-stake).
But Steemit is different— here, you donate knowledge and high-quality content for rewards. That's why they call it Proof-of-Brain.
