Is precious metals investment MLM Company? Is it reliable to work inside?

Some companies may be doing pyramid schemes under the banner of precious metals investment, but this possibility cannot be ruled out, but it is either precious metals investment or pyramid schemes. You need to see their qualification certificates and business licenses, and which exchange their company is a member of. Go up there and see if it's true. I work in a precious metal company now. I think regular companies are reliable. Be sure to identify yourself carefully.
