Didn't get "rich" per se, but I got in on dogecoin when it was at a penny, missed the peak, and ended up selling in the 30 cent range. I also picked up a ton of oil stocks in March 2020 when it bottomed out that I later sold for more than 15x their original value.
The irony is that I invested in dogecoin because Robbing Hood locked down investments into Gamestop. I didn't realize that would be such a lucky development at the time.
Those investments paid off my student loans and got me a down payment on a condo. I still have five-figures in my investment account that I'm growing into early retirement. My current focus is gambling stocks, in large part because every election year it seems like there's a smattering of states legalizing online sports betting. (MO and NE have it on the ballot for this year.)
Not fuck you money or 'rich', but life-changing.
