What Is a Milestone‑Cycle?

A Milestone‑Cycle is one full round of participation in the DOUBLEPENNIES™ EXPERIMENT.

  • Each $10 participation belongs to one specific, independently evaluated Milestone and Cycle.

  • Milestones let you monitor the movement and growth of your DoublePennies™ throughout the Cycle.

  • Completion of the Cycle may reward you up to $500 USD.

  • After completing Phase 1, your experiment transitions naturally into Phase 2: Spending for a Lifetime.

The Milestone‑Cycle is not only a tracking tool—it is your first hands‑on experience with stewardship, responsibility, and shared growth.
