Is Degas 7mall a scam? Is Degas a pyramid scheme?

Is it necessary to know the difference between pyramid selling and direct selling first? To put it bluntly, one has a certificate and the other doesn't. Why are there pyramid selling and direct selling in China? Just like driving, driving without a driver's license is driving without a license. If you have a certificate, as long as you don't crash and hit people, it doesn't pose a threat to the safety of others' lives and property, which is legal driving. If you want to drive legally, you must follow the right team and the right person.
