Pyramid scheme is the term used to define a form of fraud where participants are promised high returns on their investment but the source of that return is solely dependent on the recruitment of new members. Pyramid schemes have been around for years and have many different names. Some other synonyms for pyramid schemes include Ponzi scheme, multilevel marketing, chain referral scheme, network marketing, and matrix schemes. These schemes are designed to entice individuals with the promise of easy money, but in reality, only a few people make any money and the majority end up losing their investment. It is important to be cautious of these schemes and steer clear of any investment opportunities that seem too good to be true.
