Agreed very much. Especially in crypto you see a lot of (more than luck) success with quants/traders with no prior trading experience.
edit: actually no, I can think of a couple counter-examples of successful firms started by people with no professional trading background, but it's exceedingly rare.
PS: My original comment came off as exceedingly harsh and am sorry for that. OP if you read this mb, just got kind of triggered for a moment. However I will say the design of your site is really slick!
