You are missing the point of your own question -- Risk versus Reward is what we play in this game of Life all the time, every day, going to work for someone else, or trading-for-gain in some asset market.
Day-trading can be done for little risk -- and little gain.
Options can be bought & sold for little risk, too -- and little gain.
You are looking to work a dichotomous frame onto two activities that comprise a fully-flesh spectrum of risk and reward each and by themselves. There be no dichotomy available.
