I gamble too, but I do it with knockout options. I sometimes buy a factor 20 option, set it to 5% trailing stop loss and watch what happens.

In many cases, the option starts losing value and is automatically sold once it’s lost 5%, which isn’t too bad if you’ve invested, say, 1000 €. You lose ~50 €.

In other cases it goes up. And up. My current high score is making 450 € with one such investment.

It’s fun, and not too risky. Meanwhile, my retirement vehicles go brrr.
