I’d bet there’s few “micro-bets” that are generating any meaningful amount of money. The narrative would change and it wouldn't be getting called a "micro-bet" anymore if it did though, no? ;-) We used to just call these "side projects" which I prefer as a term for any sort of cheap experiment you throw at the wall to see if it sticks. I've had several, had two acquired for non-negligible amounts, and another has been my full time business for 10 years now.
