You take small risks with big money and stay rich.

Facts, I try my best to take calculated risks 
I wish there was a channel that educates people on here in proper investments outside crypto too tbh 
If you were to start all over again, what industry or sector would you invest in ?

To be honest, I see so many people online nowadays selling a course about how to invest in a particular sector but make most of their money from the sales of the course rather than the investment they say they’re  in

That’s so important “calculated risks”.
Most people don't know what risk is. 

Teaching how to invest is the job of those who don't really know how to invest.
