It is best to be a researcher at the brokerage research institute and where the seller is, so that you can exercise your basic skills.

Both private placement and public offering are investment-oriented, but private placement is more risky, and of course you can get more exercise if you do well.

I am a headhunter, and most of the researchers I met in private placement are average, unless I switch from a listed fund manager to a private placement, it is still very good.
