A triangle scheme (also known as a pyramid scheme) is an illegal business model where organizers promise participants high returns for recruiting new members, rather than from selling actual products or providing real services. This scam relies on a continuously expanding network of participants, with early joiners profiting from the funds of later entrants. However, due to the need for exponential growth in participation, such models are mathematically destined to fail, resulting in losses for the majority of participants (typically those who join last).
Triangle schemes have distinct characteristics that make them targets for regulatory enforcement:
Hierarchical structure: The scheme typically builds a multi-level network where a few people at the top profit from money flowing up from the large number of participants at the bottom.
Entry fees: Participants usually need to pay a certain amount as an "entry fee" or "investment" to join.
Source of returns: Returns primarily come from recruiting new members rather than from legitimate business activities.
Unsustainability: These schemes are mathematically impossible to sustain as they require new participant numbers that quickly exceed available populations.
Disguising techniques: Modern triangle schemes often masquerade as multi-level marketing, network marketing, or innovative investment opportunities.
False promises: Scheme organizers typically make unrealistic profit promises, such as "guaranteed returns" or "get-rich-quick" opportunities.
Triangle schemes have widespread negative impacts on financial markets and societies:
These schemes cause billions of dollars in losses globally each year, with victims spanning across countries and regions. After a scheme collapses, typically only 1-2% of early participants profit, while over 98% lose their investments.
In the cryptocurrency space, triangle schemes are particularly prevalent. Due to regulatory gaps and technical complexity, many scammers package traditional pyramid structures using blockchain concepts, promising unrealistic high returns through "mining rewards," "on-chain promotions," and similar tactics.
These schemes not only harm individual investors but also seriously damage industry reputation, hinder the development of genuinely valuable blockchain projects, and trigger severe regulatory crackdowns on the entire sector.
Participating in triangle schemes involves multiple risks:
Financial risk: The vast majority of participants will lose all or most of their investment.
Legal risk: In many countries, participating in promoting pyramid schemes may itself constitute illegal activity.
Reputational risk: Participants may unknowingly bring friends and family into the scheme, damaging personal relationships.
Identification challenges: Modern pyramid schemes are increasingly sophisticated and often confused with legitimate business models like MLM (multi-level marketing).
Regulatory gaps: Especially when operating across borders or involving new technologies, regulatory forces struggle to provide comprehensive coverage.
Social media propagation: Social platforms enable schemes to spread more rapidly and become harder to control.
Triangle schemes are particularly dangerous in the cryptocurrency space, as the complexity of blockchain technology and presumed anonymity provide cover for scammers, while regulatory frameworks lag behind.
Despite their simplicity, triangle schemes remain effective because they exploit human desire for quick wealth and social trust networks. Education is key to prevention, and investors should remember: any business model that relies primarily on recruiting new members rather than creating actual value is, regardless of packaging, essentially an unsustainable pyramid scheme.
