I mean if I went all in on crypto from the start and sold around end of 2017/beginning 2018 I would have been a multi billionaire. But that's not the point. Similarly, if I "only" bought far OTM option on FANG between 2010 and 2017 but not march 2014-2015 I would have also been a multibillionaire. Heck, I could have went long volatility at high leverage in February 2018 and be a good way to a billionaire. The point is, of course, if you make "good choices" one can be a multibillionaire in many ways. Alas, I am not a multibillionaire because "good choices" are good mostly in retrospect.
