Pyramid schemes are an illegal way of quickly getting rich where everybody loses at the end. The aim of this thesis is to study, through a comparative analysis, the perpetrators of fraud and the warning signs in the cases of pyramidal schemes. As a method of data processing, a comparative analysis of scientific literature was used, which includes scientific articles and books. Comparative analysis of perpetrators of fraud established their identity (age, gender, economic status, education), which was then supported by studying examples of the perpetrators of pyramid schemes (C. Ponzi, B. Madoff, B. Minkow, S. Mavrodi, P. Burks, D. W. Olivares and D. Olivares). Next, a comparative analysis of the warning signs in the above examples of pyramid schemes demonstrated that in all these cases there were indeed warning indicators of the fraud. If they had been recognized and responded to in a timely manner, many victims could have been protected. Namely, in pyramid schemes fraudsters are advertising a quick way of getting rich with minimal risks and with an initial stake that guarantees an entry into the chain. The early entry into the chain also guarantees higher earnings while all subsequent participants have little and no chance of a return on investment or earnings. A serious society's response such as frequent internal controls, ongoing education, or greater financial allocations to combatting pyramid schemes is required to prevent a significant number of the potential pyramid frauds.
