Of course, the inverse of that is also true. Even if an investment entailed reduced ROI, or losses, if they resulted in nominal upwards movement in Steem, they'd be profitable.
It's sorta a prisoner's dilemma though, because one investor's lossy investments that caused the tide to rise would cause his competitors to attain better ROI, because they didn't undertake the initiating lossy investment.
This is why cash is king.
Good point!
