What is the end of the direct seller?

I have eight friends who do so-called direct selling (in fact, it is a pyramid scheme with a direct selling license). At least one of them invested in 660 yuan, and the most one invested more than 700,000 yuan. For several years, it was crazy at first, inviting people to drink, eat, dance, party and travel, but now it has stopped and started a family civil war. Warning, no ready-made contacts, no right and no money, be careful, or you will die miserably and miss your life!
