Investment needs to be cautious, don't touch things you don't understand!
For the exhibition (commonly known as the conference), I only suggest watching a lively activity. Most of these companies, first of all, pull people to sell anxiety and tell you how to spend money in life and how others can get rich. After brainwashing, I will tell you that I can teach you how to make money. See how much money our partners and participants make. Let you invest money.
Finally, I want to say, if a pie can fall from the sky, are you sure it can fall on your head? People who really know how to invest don't even know how to check other people's companies. How dare they give money to others? Cheating is to cheat people who have never studied, want to make money and are crazy.
