Huh? Leaving Jane Street to start crypto trading isn't what I would do, but it seems to have worked out well for them. Why does that suggest they didn't choose to leave?
Sorry if my prior message was confusing, but why would a top tier company let go one of their best performers after just a half and a year out fresh of college?
Wikipedia states: ...he returned there full-time after graduating [in 2014]. In September 2017, Bankman-Fried quit Jane Street...
Seems closer to 3 years, but it doesn't state whether he started there immediately after graduating or not.
What do you suggest are the reasons for his leaving?
