MoneyCircle runs on the trusted ROSCA model: a group agrees to contribute a set amount weekly, biweekly, or monthly into a shared pool. Each round, one member takes the payout, rotating until everyone has had a turn. Payouts aren't identical, though — draw early and pay a modest fee; wait longer and earn a bonus, with annual rates running roughly 4% to 14% by position. This same idea operates worldwide: chit funds in India, committees in Pakistan, and tandas across South America.
