Definition
A 'pyramid scheme' is an illegal and unsustainable business model where participants profit primarily from recruiting new members rather than selling products or services. It relies on a hierarchical structure, with early investors benefiting from those who join later. Think of it like a house of cards 🃏 that eventually collapses. The majority of participants lose money, while only a few at the top gain significantly. Unlike legitimate businesses, pyramid schemes lack a sustainable source of revenue. These schemes are unsustainable.
