>> It would be great if I could trade equity with other engineers to slightly lower the risk of the "all in one company" issue.
Yeah, one thing I never understood is that people consider it normal to go "all in" as employee but a big no-no in terms of investing. As an employee I AM investing when I get the equity by working there and taking lower-than-market salary. No one questions or protects me from making that decision. Yet if you want to BUY equity for some startup, you are not allowed to do unless you are Accredited Investor. I think thats just not fair.
