There are segments of investors that are investing other people's money OPM and have responsibilities to the other people. There are investors that are investing their own money and do not have to be fiscally responsible for OPM.

If I invest the money of wealthy people then I may need to explain my choices to people with lawyers. This can be a difference between Angels and VC. Take my comment with a grain of salt, since I have always been self-funded.
