I'm looking into for because of interest in things like creating A.I. for stock, forex, etc. And this young genius-but-foul-mouthed-weirdo whom I follow, just created a funny video:
Long story short: He gave his goldfish $50k to trade stock, and made $1000+ in the end, tried to sell his gold fish to investors, nobody wanted it, so he used the $1000 to upgrade his goldfish's tank and the aquarium store cashier kept the change. Of course, the "goldfish" technology behind it was actually webscrapping from WallStreetBets on Reddit (the folks that crushed investors in GameStop) and the goldfish merely "picked" which side of the tank to swim to which translate to which of the two best options to trade. So the goldfish is essentially just a minor excuse to show off Michael Reeves' data science programming skill.
