Is the idea of remittance a pyramid scheme? How can we get a deeper understanding?

Absolute pyramid scheme, friends around me have been cheated. Look at the goods in Huisi Road Mall. There are no well-known domestic brands, and some brands are fakes that cannot be found. There are also goods known as international brands, which are even inferior to knockoffs without any authorized customs certificate. Look at the price that is more than ten times that of a normal brand. After joining the membership, 399 can be purchased at a 30% discount, even at a 30% discount, which is several times more expensive than the market. The most important thing is that you dare to use it? When a friend joined, another friend just gave her some cosmetics. Later, I told her that after joining the membership, she could buy the products of 1999, and then she could go offline and get the commission from 70 yuan. After further developing her membership, she will raise 40 yuan to sell things in the mall offline, and she will earn more money, earning hundreds of thousands a year ... Do you believe it? Absolute pyramid schemes, everyone should be vigilant, don't be kidnapped by family and friendship, and resolutely don't participate.
