Bitcoin pyramid schemes attract customers with unreasonably high interest rates. They offer a lucrative affiliate program for clients. Clients themselves distribute affiliate links, attracting new referral users to the fraudulent project and forming new pyramid levels.
Scammers
according to this website pay out money to investors at the expense of new receipts from investors of lower levels, leaving a part of money for themselves. The pyramids do not actually operate. Fraudsters convince clients who have received money to reinvest profits. As soon as the inflow of users ends or a large number of negative feedbacks are accumulated, the pyramid ceases to exist. All the money stays with the scammers.
