Gamifying day trading is just turning the retail market into gambling. Obvious objections will be that this has been possible for a long time now. But never did I know young men to casually play the market day to day like Wall Street Bets do now the way they would follow sports in the past.

Gamifying and advertising the shit out of options trading to make it more attractive to morons isn't, strictly speaking, an improvement of our world.

Exploring unsophisticated investors. Trading on margin used to be for extremely experienced and educated people working for a large financial institution. The risk of margin trading is extreme with unlimited losses.

Losses on long positions are limited to the value at risk. It does not matter whose money it is.
