The last question:

And if we all do the same?

reminded me of Michael Burry and others and the ETF bubble. The argument goes that passive investing is becoming the default option and the likes of Blackrock and Vanguard are buying up S&P500 companies and other indexes regardless of fundamentals. The consistent high earners on steem could end up like the S&P500 companies - growing in steem power (market cap) without necessarily needing to post quality (fundamentals).

Thanks for your food for thought.
